ORDER

v.                                                                       
COOK INC. and COOK MEDICAL LLC,                                          
               Defendants.                                               
    Edward F. Fox, Lewis A. Remele, Jr., Jeffrey R. Mulder, and Gillian L. Gilbert,
    BASSFORD REMELE; Christopher H. Yetka and Sarah DeWitt Greening,     
    LARKIN HOFFMAN DALY & LINDGREN LTD., for plaintiff.                  
    James R. Ferguson and Luiz Miranda, MAYER BROWN LLP; Nathaniel J.    
    Zylstra, FAEGRE DRINKER BIDDLE & REATH LLP, for defendants.          
    Plaintiff Security Bank & Trust Company (“Security”) is the personal 
representative of the estate of Dr. Kurt Amplatz (“the Estate”).1  Amplatz was a world-
renowned physician and inventor who developed numerous medical devices and
technologies.  For nearly 40 years, Amplatz had a working relationship with defendant
Cook Inc., which later expanded to include defendant Cook Medical LLC (“Cook
Medical”) (collectively “Cook”).  Cook paid royalties to Amplatz and used his name in

    1This action was originally brought by James H. Gilbert in his capacity as special
administrator of the Amplatz estate.  ECF No. 1-1.  After Security was appointed as the
personal representative of the estate, the parties agreed to substitute Security as the
plaintiff.  ECF Nos. 22, 24.                                              
connection with some of the products that it manufactured and distributed.  Following
Amplatz’s death in 2019, however, the relationship between Amplatz’s estate and Cook

quickly soured, and this litigation followed.  On behalf of the Estate, Security brings
breach-of-contract, right-of-publicity, and related claims against Cook Inc. and Cook
Medical.2   Cook counterclaims against the Estate for breach of contract and unjust

enrichment.                                                               
    Cook Inc. manufactures medical products, while Cook Medical acts as the
exclusive distributor of those products in North America.  The Estate’s claims arise out
of two royalty contracts between Amplatz and Cook Inc., one executed in 1983 and the

other in 1995.  The Estate alleges that Cook owes royalties to Amplatz’s estate under the
two contracts and that Cook has refused to pay those royalties despite continuing to use
Amplatz’s name.  The Estate also claims that Cook’s continued use of the Amplatz

name is a violation of Amplatz’s right of publicity.                      
    In response, Cook admits that it has stopped paying royalties to the Estate and
that it nevertheless continues to make commercial use of the Amplatz name.  Cook
contends, however, that the royalty contracts expired years before Amplatz’s death and,


    2As explained in the Court’s order on defendants’ motion to dismiss, there were
originally five Cook defendants in this action: (1) Cook Inc.; (2) Cook Medical; (3) Cook
Group, Inc.; (4) Cook Medical Holdings LLC; and (5) Cook Medical Technologies LLC. 
The Court granted defendants’ motion to dismiss the latter three defendants for lack of
personal jurisdiction.  ECF No. 290.                                      
                              -2-                                        
in any event, the Estate’s contract claims fail for lack of consideration and other reasons. 
Cook further argues that the Amplatz name has become generic or descriptive and

therefore is freely available for the public to use.  Cook counterclaims against the Estate
for unjust enrichment and breach of contract, seeking a return of royalty payments that
it made to Amplatz after the contracts allegedly expired.                 

    This matter is before the Court on Cook’s motion for summary judgment and the
Estate’s motion for partial summary judgment.  Cook seeks judgment in its favor both
on the Estate’s claims against it and on its counterclaim against the Estate for unjust
enrichment.  The Estate, for its part, moves for summary judgment on a portion of its

breach-of-contract claim against Cook and for summary judgment on all of Cook’s
counterclaims against it.                                                 
    For the reasons that follow, both motions are granted in part and denied in part. 

Specifically, the Court (1) grants Cook’s motion for summary judgment as to the
Estate’s claims for promissory estoppel and unfair competition; (2) grants the Estate’s
motion for summary judgment on all of Cook’s counterclaims; and (3) grants summary
judgment to the Estate and against Cook on the issue of whether Amplatz waived or

abandoned his right to control the commercial use of his name.  The parties’ motions are
denied in all other respects.

    The original parties to the 1983 contract were Amplatz and Cook Inc.  Whetham

Dep. 232 [ECF No. 201-1].  Under the 1983 contract, Cook Inc. agreed to pay annual
royalties to Amplatz for a limited term based on sales of four products that Amplatz
had helped to develop and that were identified in the contract.  ECF No. 277-2 at 5–6.3 

The contract contemplated that, “[s]hould new products be developed, they could be
added to the agreement, but they would have different ending dates for the term of
their agreement.”  Id. at 5.                                              
    The original parties to the 1995 contract were Amplatz and an entity called Cook

Urological Inc.  Whetham Dep. 232–33 [ECF No. 206-1].  Under the 1995 contract, Cook
Urological Inc. agreed to pay Amplatz semiannual royalties based on the sales of a
single product identified as the “Madduri/Amplatz Urethral Access Set.”  ECF No. 277-

2 at 4.  The contract was to continue until December 31, 2000, “at which time it shall be
reviewed and, if no changes are proposed, will be automatically renewed.”  Id.  
    Cook Urological Inc. was later folded into Cook Inc., which at that point became

a party to both the 1983 and 1995 contracts.  Whetham Dep. 233 [ECF No. 206-1]. 
Following the formation of Cook Medical Technologies LLC (“CMT”) as an intellectual-
property holding company in 2010, the Amplatz contracts were assigned to CMT, along

    Cook Inc. funded the Amplatz royalty payments up until 2017, after which those

payments were funded by CMT.  Whetham Dep. 257, 264–65 [ECF No. 206-1];   
Richardson Dep. 34 [ECF No. 277].  In some of Cook’s cover letters accompanying the
royalty payments—letters that were written long after 2000, when Cook now claims the
last of the two contracts expired—Cook referred to the parties’ “contract” and otherwise

implied that Cook regarded the 1983 and 1995 contracts as remaining in effect.  Irie
Dep. 57 [ECF 206-2]; ECF No. 277-5 (2012 and 2014 letters from “Cook Medical” to
Amplatz stating that “[t]he royalty agreement is now entering” the 31st, 32nd, and 33rd

“year of the contract,” respectively).                                    
    In late 2019, Amplatz’s estate-planning counsel contacted Cook to ask that the
royalty payments be made to a trust instead of to Amplatz personally.  Whetham
Dep. 78–79, 81–82, 106–07 [ECF No. 206].  Cook was prepared to approve the change,

    4As noted, Cook contends that the Amplatz contracts were no longer in force by
the time CMT was formed.  Viewing the record in the light most favorable to the Estate,
however, the Court finds that there is sufficient evidence for a jury to find that the 1983
and 1995 contracts were still in force and therefore were assigned to CMT.

died.  After learning of Amplatz’s death and consulting with outside counsel, Cook
decided to terminate the royalty payments.  Whetham Dep. 91, 253–54 [ECF Nos. 206,

206-1].  Even though Cook’s original position seemed to be that Amplatz was entitled to
royalty payments until the end of his life, Cook refused to pay Amplatz royalties for the
months preceding his death in late 2019.  Irie Dep. 86–87, 108 [ECF No. 206-2]; Whetham

Dep. 82, 111, 191–92 [ECF Nos. 206, 206-1].

                       A.  Standard of Review                            
    Summary judgment is warranted “if the movant shows that there is no genuine

dispute as to any material fact and the movant is entitled to judgment as a matter of
law.”  Fed. R. Civ. P. 56(a).  A dispute over a fact is “material” only if its resolution
might affect the outcome of the suit under the governing substantive law.  Anderson v.

Liberty Lobby, Inc., 
477 U.S. 242, 248
 (1986).  And a dispute over a fact is “genuine” only
if “the evidence is such that a reasonable jury could return a verdict for the nonmoving
party.”

inferences are to be drawn in his favor.”

                       B.  The Estate’s Claims                           
               1.  Contract and Related Claims (Counts 1–5)              

    Cook moves for summary judgment on the Estate’s contract claims (Counts 1
and 2) and on the Estate’s alternative claims for unjust enrichment and breach of the
covenant of good faith and fair dealing.5  The Estate moves for partial summary

judgment in its favor, seeking a ruling that the royalty contracts were in force through
2019—or, in the alternative, at least through the date of Amplatz’s death—and
awarding the Amplatz estate the corresponding amount of royalties.  The Court denies
both parties’ motions on these claims.                                    

    As the Court explained in its order on Cook’s motion to dismiss, there is ample
evidence that the parties had one or more implied-in-fact contracts at least through the
date of Amplatz’s death.  But the terms and exact duration of that contract or contracts

are disputed factual issues that must be resolved by a jury.  For that reason, all
arguments that depend on the duration or terms of the contracts—such as arguments
that Cook terminated the contracts, or that the contracts terminated upon Amplatz’s



    5The Estate has withdrawn its claims for promissory estoppel and unfair
competition.  See ECF No. 310 at 28.  Accordingly, the Court treats Cook’s motion for
summary judgment on those claims as unopposed and grants it.  See Fed. R. Civ.
P. 41(a)(2) (“Except as provided in Rule 41(a)(1), an action may be dismissed at the
plaintiff’s request only by court order, on terms that the court considers proper.”).

death, or that the contracts survived Amplatz’s death—will have to be resolved by a
jury.                                                                     

    Cook argues that, even if the contracts still exist, Cook Inc. and Cook Medical are
not parties to the contracts, as Cook Inc. assigned the contracts to non-party CMT in
2010.  Cook points to no evidence that Amplatz ever consented to this assignment,

however.  As a result, Cook Inc. remains responsible for performing its duties under the
contracts, whether or not it assigned the contracts to CMT.  See Epland v. Meade Ins.
Agency Assocs., Inc., 
564 N.W.2d 203, 207
 (Minn. 1997) (“A party may not divest itself of

liability on a contract without the consent of the other party to the contract.”); Vetter v.
Sec. Cont’l Ins. Co., 
567 N.W.2d 516, 521
 (Minn. 1997) (“the original obligor may not
divest itself of liability without the consent of the obligee”); Tony & Leo, Inc. v. U.S. Fid.
& Guar. Co., 
281 N.W.2d 862, 865
 (Minn. 1979) (“A mere assignment does not absolve

the assignor of its obligations under a contract.”).                      
    In addition, CMT licenses the contracts back to Cook Inc. to practice.  Whetham
Dep. 230, 242, 249 [ECF No. 206-1].  As a result, even if Cook Inc. was somehow

divested of its contractual duties by virtue of the 2010 assignments, Cook Inc. would
nevertheless be liable on the contracts as a result of this license.  S O Designs USA, Inc. v.
Rollerblade, Inc., 
620 N.W.2d 48, 54
 (Minn. Ct. App. 2000) (explaining that a license is


                              -8-                                        
simply a form of assignment and that, as a result, either the assignee or, upon the
assignee’s failure, the assignor, were liable to pay royalties).          

    Similarly, a jury could find that either Cook Inc. or CMT impliedly granted Cook
Medical a license.  Indeed, if the jury finds that the royalty contracts still exist, the jury
will almost certainly also find that Cook Medical has a license to practice rights under

those contracts, and almost certainly find that Cook Medical is obligated to pay
royalties.  
Id.
  Alternatively, the jury could find that, through its conduct marketing
Amplatz-branded products and paying royalties to Amplatz, Cook Medical entered into
(or took over) a contract or contracts with Amplatz, the terms and duration of which

would be fact questions for the jury.                                     
    Cook next argues that the contracts fail for lack of consideration.  Specifically,
Cook argues that it received nothing of value in return for its royalty payments because

the Amplatz name had become a generic or descriptive term, and therefore lacked
economic value.  But whether the Amplatz name had become generic or       
descriptive—and, if so, whether Cook nevertheless received something of value in
return for its royalty payments—are jury issues, and Cook is therefore not entitled to

summary judgment on this ground.  Cf. Ford Motor Co. v. Summit Motor Prods., Inc., 
930 F.2d 277
, 292 n.18 (3d Cir. 1991) (“The characterization of a mark is a factual issue for
the jury.”).                                                              

                              -9-                                        
    Cook next contends that the alleged contract or contracts are unenforceable
under the statute of frauds.  See 
Minn. Stat. § 513.01
(1) (to be enforceable, a contract that

“by its terms is not to be performed within one year from the making thereof” must be
in writing).  Obviously, whether either alleged contract must be in writing depends on
its terms, and those terms are disputed.                                  

    Cook argues that, if the Estate is correct that royalties are contractually payable
to Amplatz’s heirs, the contracts are necessarily incapable of being performed within a
year and therefore must be in writing.  This argument is misplaced, however, as the
statute of frauds does not apply to a contract unless the contract by its terms cannot

possibly be performed within one year.  
Id.
  It does not matter whether performance
within a year is likely.  See Eklund v. Vincent Brass & Aluminum Co., 
351 N.W.2d 371, 375
(Minn. Ct. App. 1984) (“The test is simply whether the contract by its terms is capable of

full performance within a year, not whether such occurrence is likely.” (citation
omitted)).  Accordingly, when the length of a contract is measured by a lifetime (or
lifetimes), the contract is capable of performance within a year (because the relevant life

could end at any moment), and the statute of frauds therefore does not apply.  See 
id.
at 375–76 (holding that a contract for permanent employment until retirement was
capable of performance within a year because, among other things, the employee could


                              -10-                                       
have died within the year).  Cook is not entitled to summary judgment on the basis of
the statute of frauds.                                                    

    Finally, the Court denies Cook’s motion for summary judgment as to the Estate’s
alternative claims for unjust enrichment and breach of the duty of good faith and fair
dealing.  Cook argues that the Estate’s unjust-enrichment claim fails because the

Amplatz name had become generic or descriptive and therefore had no economic value. 
Again, though, this is a disputed issue of fact.  Cook also argues that the unjust-
enrichment claim fails because an “adequate legal remedy” exists and contends that this
is true “even when a plaintiff’s legal claims lack merit,” citing Loftness Specialized Farm

Equipment, Inc. v. Twiestmeyer, 
742 F.3d 845, 854
 (8th Cir. 2014).  See ECF No. 296 at 27. 
In Loftness, however, the unjust-enrichment claim failed because the parties’ relationship
was governed by contracts.  
Id.
 at 854–55 (“Having struck this deal, Twiestmeyer, Hood,

and T & A cannot rewrite it via unjust enrichment.”).  Here, however, the existence of a
contract is in dispute, and the Estate can therefore pursue its claim of unjust enrichment
in the alternative.                                                       

    As for the duty of good faith and fair dealing, Cook’s only argument is that,
because the parties have no enforceable contract, there can be no implied contractual
duty of good faith.  Again, however, the existence of a contract between the parties is a
disputed factual issue.                                                   

                              -11-                                       
                         2.  Right of Publicity                           
     Cook also moves for summary judgment on the Estate’s claim for violation of

Amplatz’s right of publicity.  See Ventura v. Titan Sports, Inc., 
65 F.3d 725, 730
 (8th Cir.
1995) (“We believe that the Minnesota Supreme Court would recognize the tort of
violation of publicity rights.”); Paisley Park Enters., Inc. v. Boxill, 
299 F. Supp. 3d 1074, 1084
 (D. Minn. 2017) (“The right of publicity under Minnesota common law is
descendible and enforceable by the decedent’s estate.”).                  
                          a.  Abandonment                                 

     Cook first argues that Amplatz had no protectable right of publicity because he
waived or abandoned his right to control the use of his name for commercial purposes. 
Cook points to evidence that, in 1999, Boston Scientific notified Amplatz that it would
no longer pay him royalties, but would nevertheless continue to use his name to sell

products.  Defts.’ Ex. 4.  Cook also cites other examples of companies who apparently
use the Amplatz name for commercial purposes without paying royalties.  Cook
compares the right of publicity to a trademark, which an owner can abandon through

acts of omission (as well as commission) that cause the mark to lose its significance as a
mark.  See 
Minn. Stat. § 333.18
, subd. 6(2).                              
    The right of publicity certainly bears some similarity to trademark law, but the
Court does not agree that the concept of abandonment should apply in this context. 

                               -12-                                       
“One’s birth name is an integral part of one’s identity; it is not bestowed for commercial
purposes, nor is it ‘kept alive’ through commercial use.”  Abdul-Jabbar v. Gen. Motors

Corp., 
85 F.3d 407, 411
 (9th Cir. 1996); cf. Price v. Hal Roach Studios, Inc., 
400 F. Supp. 836, 846
 (S.D.N.Y. 1975) (characterizing as “nonsensical” the argument that, through non-use,
a person could lose rights in his own name and likeness), abrogated on other grounds by

Pirone v. MacMillan, Inc., 
894 F.2d 579
, 585–86 (2d Cir. 1990) (recognizing that New York
courts have held that the only right of publicity under New York law is statutory). 
Consequently, “[a] proper name . . . cannot be deemed ‘abandoned’ throughout its

possessor’s life, despite his failure to use it, or continue to use it, commercially.”  Abdul-
Jabbar, 
85 F.3d at 411
.                                                    
    The Court agrees with this analysis and finds it equally applicable to Cook’s
argument that Amplatz waived or abandoned his right to control the commercial use of

his name by failing to enforce that right against Boston Scientific and other companies. 
The Court holds that, under Minnesota law, an individual’s right to control the
commercial use of his or her name cannot be abandoned or waived by omission—that is,

by a failure to enforce—at least during that individual’s lifetime.        
                     b.  Generic or Descriptive Term                      
    Cook next argues that, by 2019, the name “Amplatz” had become a generic or
descriptive term to which Amplatz no longer had an exclusive right.  Cf. 2 McCarthy on

                               -13-                                       
Trademarks and Unfair Competition § 13:24 (5th ed.) (“A personal name, even though
originally used as a valid mark, may, through public usage, become a generic

designation for a genus of goods.  As such, a generic personal name designation is in the
public domain and free for all to use.”).                                  
    Whether this defense should apply to a right-of-publicity claim is a difficult legal

question.  Rather than resolving that question now, the Court will wait until a jury
decides the factual issue of whether “Amplatz” has, in fact, become generic or
descriptive.  Cf. Ford Motor Co., 930 F.2d at 292 n.18 (“The characterization of a mark is a
factual issue for the jury.”).  If Cook succeeds in persuading the jury that “Amplatz” has

become generic or descriptive, cf. Murphy Door Bed Co. v. Interior Sleep Sys., Inc., 
874 F.2d 95
, 101 (2d Cir. 1989) (placing the burden of proof on the defendant to show that the
public expropriated a name and rendered it generic), then the Court will decide whether

“genericization” is a valid defense to a right-of-publicity claim.  Cook’s motion for
summary judgment is therefore denied as to the Estate’s right-of-publicity claim.
                        3.  Punitive Damages                              

    Finally, Cook moves for summary judgment on the Estate’s claim for punitive
damages.  Factual issues preclude summary judgment on this claim, however, and
Cook’s motion is therefore denied.                                         


                               -14-                                       
                          C.  Cook’s Claims                               
    As noted, Cook brings counterclaims for unjust enrichment and breach of

contract.  The Estate moves for summary judgment on both claims, and Cook seeks
summary judgment in its favor on its unjust-enrichment claim.              
                       1.  Statute of Limitations                         

    The Court agrees with the Estate that both of Cook’s counterclaims are barred by
Minn. Stat. § 524.3-803
(a), which imposes a limitations period for claims against an
estate.  Specifically, § 524.3-803(a) provides that a claim against a decedent’s estate that
arose before the decedent’s death is time-barred unless presented as follows:

         (1) in the case of a creditor who is only entitled, under the    
         United States Constitution and under the Minnesota               
         Constitution, to notice by publication under section 524.3-801,  
         within four months after the date of the court administrator’s   
         notice to creditors which is subsequently published pursuant     
         to section 524.3-801;                                            
         (2) in the case of a creditor who was served with notice under   
         section 524.3-801(c), within the later to expire of four months  
         after the date of the first publication of notice to creditors or
         one month after the service;                                     
         (3) within one year after the decedent’s death, whether or not   
         notice to creditors has been published or served under section   
         524.3-801.  Claims authorized by section 246.53, 256B.15, or     
         256D.16 must not be barred after one year as provided in this    
         clause.                                                          
Id.                                                                        
                               -15-                                       
     The parties appear to agree that subsection (a)(3) is the relevant provision in this
case.  As Cook first brought a counterclaim on December 6, 2021, and as that was more

than two years after Amplatz’s death, Cook’s counterclaims are barred under the
statute.6  See ECF No. 6.                                                  
    Cook makes a number of arguments to the contrary, all of them unavailing:  

                           a.  Jurisdiction                               
    Citing Marshall v. Marshall, 
547 U.S. 293
 (2006), Cook first argues that the “probate
exception” to federal-court jurisdiction bars this Court from applying 
Minn. Stat. § 524.3
-

803.  According to Cook, the Court is required to adjudicate the merits of its unjust-
enrichment claim without regard to the applicability of § 524.3-803.  If Cook prevails,
says Cook, it can then present its claim to the probate court, at which point the Estate can
raise its statute-of-limitations defense to that claim.                    

    This procedure would make no sense, and, not surprisingly, nothing in Marshall
requires it.  To the contrary, Marshall emphasized that the probate exception is quite
narrow and only precludes federal courts from (1) probating or annulling a will,

(2) administering a decedent’s estate, and (3) interfering with a probate court’s exercise
of in rem jurisdiction over a res.  Marshall, 547 U.S. at 311–12 (“Thus, the probate

     6Notably, Cook initially counterclaimed only for unjust enrichment.  See ECF
No. 6.  Cook did not bring its breach-of-contract claim until April 2023, about three-and-
a-half years after Amplatz’s death.                                       
                               -16-                                       
exception reserves to state probate courts the probate or annulment of a will and the
administration of a decedent’s estate; it also precludes federal courts from endeavoring

to dispose of property that is in the custody of a state probate court.”); Kiddie v. Copeland,
741 F. App’x 355
, 356 (8th Cir. 2018) (per curiam) (“The probate exception only applies to
three types of cases: the probate or annulment of a will, the administration of a

decedent’s estate, and the exercise of in rem jurisdiction over property already asserted
within the in res jurisdiction of a state court.”).                        
    Consequently, “if the plaintiff seeks an in personam judgment against the

defendant and not a res in the custody of a state court, the federal district court may
properly adjudicate the claim.”  McAninch v. Wintermute, 
491 F.3d 759, 766
 (8th Cir. 2007)
(cleaned up); see also Kiddie, 741 F. App’x at 356 (“Seeking an in personam judgment
against a person for their conduct with property that ultimately became estate property

is not within the probate exception to federal jurisdiction.”).  That is exactly the situation
here with respect to Cook’s claims against the Estate.                     
    This Court has subject-matter jurisdiction over Cook’s claims.  It would be

exceedingly strange if this Court could exercise that subject-matter jurisdiction to resolve
everything about Cook’s claims—substantively and procedurally—except the question
of whether the claims are timely under state law.  The application of § 524.3-803 does not
implicate any of the exceptions to federal jurisdiction, and Cook cites to no case holding

                               -17-                                       
that a federal court can adjudicate everything about a claim against an estate except the
application of the statute of limitations.  The Court therefore rejects Cook’s argument

that the Court lacks jurisdiction to apply § 524.3-803.                    
                            b.  Peterson                                  
    Cook next argues that, under Peterson v. Marston, 
362 N.W.2d 309
 (Minn. 1985), its

communications with the Estate’s attorneys in February and March 2020 qualify as 
presentation of a timely claim against the Estate.  The Court disagrees.   
    Peterson addressed what is necessary to “present” a claim against an estate within

the meaning of 
Minn. Stat. § 524.3-804
 (“Manner of presentation of claims”).  Section
524.3-804 authorizes two types of presentment: (1) delivering to the personal
representative or filing with the court administrator “a written statement of the claim
indicating its basis, the name and address of the claimant, and the amount claimed,” or

(2) commencing “a proceeding against the personal representative in any court where
the personal representative may be subjected to jurisdiction . . . within the time limited
for presenting the claim.”                                                 

    In Peterson, the Minnesota Supreme Court held that a letter inquiring about the
status of a contract for deed sent to an attorney for an estate qualified as a written
statement of a claim under § 524.3-804.  Peterson, 
362 N.W.2d at 313
.  The court focused
on whether the letter communicated a present intent to make a claim.  
Id.
 at 312

                               -18-                                       
(discussing whether the language of the letter showed a “present intent to make a
claim”).  The court held that the letter communicated such an intent, as (1) the letter was

sent in response to a published notice about how to make claims against the estate;
(2) the letter was sent to the estate attorney identified in the published notice; (3) the
claimants mentioned the contract for deed and stated that they understood that they

needed to present their claim against the estate within four months; and (4) the claimants
asked if their contract would be affected and whether “any action is necessary.”  
Id.
 at
312–13.                                                                    
    In contrast to Peterson, Cook’s February and March 2020 correspondence with the

estate attorneys does not demonstrate a present intent to make a claim.  To the contrary,
the final email from Cook to the Estate’s attorneys states that “Cook is currently
weighing its options with respect to these [royalty] payments, none of which should

have ever been made.”  Defs.’ Ex. 30 (March 16, 2020 email).  A statement that a party is
“weighing its options” is not a demand or assertion of a right to payment.  Peterson, 
362 N.W.2d at 312
 (“A claim is a demand, an assertion of the right to payment.”).  

    The very different context of the correspondence in Peterson underscores the
Court’s conclusion.  Peterson involved an undisputed contract under which the claimants
obviously expected—and were contractually entitled to—ongoing payments.  Here, by
contrast, in the months after Amplatz’s death, what eventually became the parties’

                               -19-                                       
dispute over the nature of the Amplatz/Cook relationship and the basis for the many
years of royalty payments that Cook had made to Amplatz was just beginning to take

shape.  In light of that context, Cook’s correspondence is plainly not “evidence of present
intent to make a claim.”  
Id.
                                              
    There are a couple of additional reasons why Cook’s correspondence fails to

satisfy 
Minn. Stat. § 524.3
-804—which, again, requires “a written statement of the claim
indicating its basis, the name and address of the claimant, and the amount claimed.” 
Cook has been careful, throughout these proceedings, to insist that the separate
corporate identities of the various Cook entities be scrupulously respected.7  In the

correspondence on which it relies, however, Cook’s attorneys repeatedly refer to the
Cook entities as a group.  See Defts.’ Exs. 28–30.  Consequently, the “name . . . of the
claimant” is not clear from this correspondence.                           

    The “amount claimed” is even less clear.  Peterson involved a contract for deed
requiring the decedent to make payments in specific amounts on specific dates.  Peterson,
362 N.W.2d at 313
.  The estate attorney was familiar with the contract, as his firm had

drafted it, he had notarized it, and he was generally aware of its contents.  
Id.
 (“Because
of his familiarity with the contract, specific mention of the amount due was not
necessary; [the estate attorney’s] familiarity with and access to the contract constituted

     7“Cook” is merely the shorthand that the Court has used to refer to the two
remaining defendants in order to improve the readability of this order.   
                               -20-                                       
notice of the amount claimed.”).  Here, by contrast, the parties’ correspondence
demonstrates that the estate attorneys were unfamiliar with the nature of the

Amplatz/Cook contractual relationship.  Indeed, most of the exchange between the
estate attorneys and Cook’s attorneys involved the estate attorneys trying to get the
information they needed to figure out the nature of the Amplatz/Cook relationship. 

Obviously, then, those attorneys would have no idea how to calculate the amount of any
claim that Cook might assert.                                              
    True, Cook’s emails mention certain dollar amounts.  See Defts.’ Ex. 30 (March 16,
2020, email mentioning that “in the period 2006–2018 alone Cook paid more than $5.5

million to Dr. Amplatz . . . even though Cook had no legal or contractual obligation to do
so”).  But nowhere does Cook identify the amount of any claim against the estate.  To the
contrary, the emails make clear that the dollar amounts they mention are not the total

value of any claim that one or more of the Cook companies might assert against the
Estate.  See ECF No. 291 at 30 ¶ 18 (unjust-enrichment claim for payments Cook made to
Amplatz “[f]rom 2000 to at least August 2019”); 
id.
 at 31–32 ¶ 29 (breach-of-contract

claim for payments made “for at least the years 2015–2018”).               
    For all of these reasons, Cook’s February and March 2020 correspondence does
not constitute a “claim” for purposes of § 524.3-804 and Peterson.         


                               -21-                                       
                    c.  
Minn. Stat. § 524.3-803
(c)(4)(ii)                 
    Cook next contends that the Court should allow its claim under 
Minn. Stat. § 524.3-803
(c)(4)(ii).  That provision authorizes a court to permit a late claim “for cause
shown.”  To establish cause, a claimant must establish a “significant reason” for the
delay.  In re Est. of Kotowski, 
704 N.W.2d 522, 531
 (Minn. Ct. App. 2005).  “A petition for a

late claim may be granted in cases of ‘hardship, misunderstanding, and diligent but
mistaken procedures’ but not in cases of ‘unexplained and inexcusable lack of
diligence.’”  
Id.
 (quoting In re Est. of Thompson, 
484 N.W.2d 258
, 261–62 (Minn. Ct. App.

1992)).                                                                    
    Cook argues that it has established cause because it did not receive notice under
Minn. Stat. § 524.3-801
.  As Cook acknowledges, however, the one-year statute of
limitations applies regardless of whether the creditor received notice.  See 
Minn. Stat. § 524.3-803
(a)(3) (claims must be brought “within one year after the decedent’s death,
whether or not notice to creditors has been published or served under section
524.3-801”).  More importantly, Cook learned of Amplatz’s death within just a few

weeks after it occurred.  Whetham Dep. 111–12 [ECF No. 206].  Yet Cook did not assert a
claim against Amplatz’s estate until December 6, 2021, more than two years later.  ECF
No. 6.  As Cook failed to act diligently, the Court will not excuse its late presentation.


                               -22-                                       
    In sum, the Court grants the Estate’s motion for summary judgment on Cook’s
counterclaims for unjust enrichment and breach of contract because those claims are

barred by the statute of limitations.                                      
                          2.  Recoupment                                  
    Finally, Cook argues that, even if its unjust-enrichment claim is time-barred, that

claim may nevertheless serve as a recoupment defense.  See Household Fin. Corp. v. Pugh,
288 N.W.2d 701, 703
 (Minn. 1980) (“a defense in the nature of recoupment is generally
permitted even though the applicable statute of limitations would have barred an
independent action on the same claim”).  A claim for recoupment “must arise out of the

same transaction that is the subject matter of the plaintiff’s action and it can only be
utilized to reduce or avoid the plaintiff’s recovery.”  
Id. at 704
.        
    The Court does not understand how the Estate could recover on any of its claims

against Cook and yet also be found liable to Cook for unjust enrichment.  If the Estate
recovers on it contract claims, Cook would be precluded from recouping anything on an
unjust-enrichment theory.  See Graff v. Brighthouse Life Ins. Co., 
109 F.4th 1118, 1124
 (8th

Cir. 2024) (“Under Minnesota law, equitable remedies, including recovery under a
theory of unjust enrichment, ‘cannot be granted where the rights of the parties are
governed by a valid contract.’” (quoting Loftness, 
742 F.3d at 854
)).  If the Estate recovers
on its own unjust-enrichment claim, it is hard to imagine how Amplatz could also have

                               -23-                                       
been unjustly enriched by Cook so as to reduce the Estate’s recovery.  And finally, if the
Estate recovers on its right-of-publicity claim, then Cook never had the right to use the

Amplatz name for free, and the requirement that it pay Amplatz for using his name
would not be “unjust.”                                                     
    Setting this aside, Cook’s unjust-enrichment claim fails on the merits.  “Unjust

enrichment is an equitable doctrine that allows a plaintiff to recover a benefit conferred
upon a defendant when retention of the benefit is not legally justifiable.”  Caldas v.
Affordable Granite & Stone, Inc., 
820 N.W.2d 826, 838
 (Minn. 2012), superseded by statute on

other grounds as stated in Hall v. City of Plainview, 
954 N.W.2d 254
, 270 (Minn. 2021). 
“[U]njust enrichment claims do not lie simply because one party benefits from the efforts
or obligations of others . . . .”  First Nat’l Bank of St. Paul v. Ramier, 
311 N.W.2d 502, 504
(Minn. 1981).  “[T]he plaintiff must show that the defendant was enriched illegally or

unlawfully, or in a manner that is morally wrong.”  Herlache v. Rucks, 
990 N.W.2d 443
,
450 (Minn. 2023) (cleaned up).  “[U]njust enrichment should not be invoked merely
because a party has made a bad bargain.”  Cady v. Bush, 
166 N.W.2d 358, 362
 (Minn.

1969).                                                                     
    Applying these principles, no reasonable factfinder could conclude that Amplatz
was unjustly enriched by the royalty payments he received from Cook.  The undisputed
evidence establishes that, despite the expiration terms in the written contracts to which it

                               -24-                                       
now points, Cook knowingly and deliberately chose to continue making royalty
payments to Amplatz, including for new products that Cook knew were not covered by

the written contracts.  Cook (1) paid royalties on a regular basis for nearly 20 years after it
now claims that it no longer was contractually obligated to do so; (2) characterized the
royalty payments as being pursuant to a contract in its communications with Amplatz;

and (3) put each royalty payment through layers of review, including by a manager and
a corporate officer.  Richardson Dep. 32, 36–42, 89–90 [ECF No. 277].      
    Even when a Cook employee raised questions about the royalty payments, Cook
insisted on continuing to make them.  Ryan Dep. 29–30, 45–48, 78, 155 [ECF No. 206-3]

(employee was told to “leave it alone” and later remarked to an employee in the
accounting department that the payments were “untouchable until death”).  And when
an issue arose regarding payments to Frank Kotula, a colleague of Amplatz with whom

Amplatz split his Cook royalties, Cook (through its general counsel) took the position
that Kotula was entitled to payments through the end of his life.  ECF No. 315-9; ECF
No. 277-2 at 5.  Cook has no coherent explanation for why Kotula, but not Amplatz,

would be entitled to payments until the end of his life.                   
    All of this evidence establishes beyond any doubt that Cook make a deliberate
decision to continue to make the royalty payments until 2019.  There is, however, no
competent evidence as to why Cook decided to do so.  Cook contends that it was paying

                               -25-                                       
royalties, not because it was contractually bound, but because it made a “business
decision” to do so in the belief that there was economic value in Amplatz’s name.  But

when the Court pressed Cook on this assertion, Cook was unable to cite any evidence
concerning who made the “business decision” to continue paying royalties, much less
why that “business decision” was made.8  ECF No. 340 at 44–54; Ryan Dep. 15–16, 31

[ECF No. 315] (Cook cannot identify who made the alleged business decision); Whetham
Dep. 85 [ECF No. 298-4] (Cook does not know who made the decision).  Instead, Cook
just kept repeating the mantra that at some (unidentified) point some (unidentified)
person made a “business decision” for some (unidentified) reason to continue to pay

royalties to Amplatz.                                                      


     8Cook contends that a written Cook policy dating from the 1980s demonstrates
that Cook would pay royalties for the use of a physician’s name even in the absence of a
contract.  See ECF No. 321 at 7; Defts.’ Ex. 21 ¶ 7.                      
     There are two problems with Cook’s argument.  First, the policy says no such
thing.  The policy is entitled “Policy on Royalty Agreements” and is clearly discussing
contractual relationships; the final paragraph, to which Cook points, begins by stating
that “[i]f COOK INCORPORATED and the inventor-developer arrive at an      
agreement . . . .”  Defts.’ Ex. 21 ¶ 7.  Nowhere does the policy mention making
payments in the absence of a contract.  Second, because there is no evidence concerning
who made the alleged business decision, there is also no evidence that he or she knew
of or was following this policy, or even that the policy was in effect at the unknown
time that the decision was made.  (Notably, the cover letter accompanying the policy
stated that “[t]his policy [is] certainly not to be considered the only way that we could
come to an agreement with a developer . . . .”  Defts.’ Ex. 21.)          
                               -26-                                       
    This will not do.  Corporate employees typically do not make a “business
decision” to pay for nothing.  Without any evidence as to why Cook made the “business

decision” to continue to pay royalties, Cook cannot show that anything unjust occurred. 
Indeed, the sparse evidence in the record suggests that Cook decided to continue the
royalty payments on account of its long and close relationship with Amplatz and

because it was continuing to benefit from that relationship.  Ryan Dep. 15 [ECF No. 315]
(testifying that Cook continued paying royalties both because of the belief that the
Amplatz name was valuable and because of the parties’ relationship); Whetham Dep.
108 [ECF No. 206] (discussing email referring to Amplatz’s lengthy relationship with the

“Cook family”).                                                            
    Cook complains that Amplatz never informed it that other medical-device
companies were using Amplatz’s name without compensating him.  Again, because

there is no evidence as to why Cook continued paying royalties, there is also no evidence
that such information would have made any difference to Cook.9  Setting that aside,

     9Cook points out that the 1995 contract granted Cook “the exclusive right to use
[Amplatz’s] name in the descriptive title of the stated product,” as well as the exclusive
right to manufacture that product.  ECF No. 313 at 4.  The “stated product” in the 1995
contract was discontinued in 2002, however, and Cook does not point to anything that
would give rise to an implied exclusivity provision as to other products.  Id.; Ryan Dep.
67–69 [ECF No. 315].  Indeed, any such implication is severely undermined by the fact
that the parties clearly knew how to agree on exclusivity, yet chose not to do so in the
1983 contract, which covered more products than the 1995 contract.        
                                                       (continued...)     
                               -27-                                       
nothing in the parties’ written contracts required Amplatz to prevent other medical-
device companies from using his name or to inform Cook how much (if anything) he

was being paid by other companies who used his name.  Nor has Cook pointed to
anything in the parties’ subsequent course of dealing that would have given Amplatz
any idea that Cook expected him to provide such information.               

    Indeed, under Cook’s version of events, Cook had no contractual or other legal
obligation to pay royalties, but nevertheless made a “business decision” to continue to
pay money that it was not obligated to pay.  Again, its argument that it would have
made a different “business decision” if it had learned that other companies were (legally

or illegally) using the Amplatz name without paying for a license falters on the fact that
there is no evidence explaining why Cook continued to make payments.  Setting that
aside, if Cook’s account is accurate, then Cook believed that it had no legal obligation to

pay Amplatz but decided to do so anyway.  Ryan Dep. 22 [ECF No. 315].  If Cook

    9(...continued)                                                       
     Moreover, the 1995 contract did not impose a duty on Amplatz to police others’
use of his name, which is something that Cook could have done as easily as Amplatz. 
See Restatement (Third) of Unfair Competition § 46 (1995) (“[W]hen the license is
exclusive, courts have held that the licensee has standing to object to commercial uses
that infringe on the scope of the licensee’s exclusive right”); Hillerich & Bradsby Co. v.
Christian Bros., 
943 F. Supp. 1136, 1138
 (D. Minn. 1996) (granting exclusive licensee’s
motion for a preliminary injunction against competitor’s use of player’s name on sports
equipment).  The Court thus sees little basis for implying an exclusivity provision in the
parties’ relationship, and particularly not such a provision that imposes duties on
Amplatz that were not imposed under the written terms of the 1983 and 1995 contracts.
                               -28-                                       
believed that it had no legal obligation to pay Amplatz, Cook can hardly complain that
other companies reached the same conclusion, or that Amplatz did not attempt to

prevent other companies from using his name.  In short, even under Cook’s version of
events, there is nothing unjust about Amplatz retaining the royalty payments.  
    For these reasons, the Court grants the Estate’s motion for summary judgment on

Cook’s recoupment defense.10                                               

ORDER

    Based on the foregoing, and on all of the files, records, and proceedings herein, IT
IS HEREBY ORDERED THAT:                                                    

    1.   Defendants’ motion for summary judgment [ECF No. 294] is GRANTED 
         IN PART and DENIED IN PART.                                      
         a.   The motion is GRANTED as to plaintiff’s claims of promissory

              estoppel and unfair competition.                            
         b.   The motion is DENIED in all other respects.                 
    2.   Plaintiff’s motion for partial summary judgment [ECF No. 308] is 
         GRANTED IN PART and DENIED IN PART.                              

         a.   The motion is GRANTED as to:                                

     10Cook does not contend that its counterclaim for breach of contract would entitle
it to recoupment.  See ECF No. 321 at 19.  The Court therefore grants summary
judgment as to the entirety of Cook’s recoupment defense.

                      of contract.

    Zylstra, FAEGRE DRINKER BIDDLE & REATH LLP, for defendants.          
    Plaintiff Security Bank & Trust Company (“Security”) is the personal 
representative of the estate of Dr. Kurt Amplatz (“the Estate”).1  Amplatz was a world-
renowned physician and inventor who developed numerous medical devices and
technologies.  For nearly 40 years, Amplatz had a working relationship with defendant
Cook Inc., which later expanded to include defendant Cook Medical LLC (“Cook
Medical”) (collectively “Cook”).  Cook paid royalties to Amplatz and used his name in

    1This action was originally brought by James H. Gilbert in his capacity as special
administrator of the Amplatz estate.  ECF No. 1-1.  After Security was appointed as the
personal representative of the estate, the parties agreed to substitute Security as the
plaintiff.  ECF Nos. 22, 24.                                              
connection with some of the products that it manufactured and distributed.  Following
Amplatz’s death in 2019, however, the relationship between Amplatz’s estate and Cook

quickly soured, and this litigation followed.  On behalf of the Estate, Security brings
breach-of-contract, right-of-publicity, and related claims against Cook Inc. and Cook
Medical.2   Cook counterclaims against the Estate for breach of contract and unjust

enrichment.                                                               
    Cook Inc. manufactures medical products, while Cook Medical acts as the
exclusive distributor of those products in North America.  The Estate’s claims arise out
of two royalty contracts between Amplatz and Cook Inc., one executed in 1983 and the

other in 1995.  The Estate alleges that Cook owes royalties to Amplatz’s estate under the
two contracts and that Cook has refused to pay those royalties despite continuing to use
Amplatz’s name.  The Estate also claims that Cook’s continued use of the Amplatz

name is a violation of Amplatz’s right of publicity.                      
    In response, Cook admits that it has stopped paying royalties to the Estate and
that it nevertheless continues to make commercial use of the Amplatz name.  Cook
contends, however, that the royalty contracts expired years before Amplatz’s death and,


    2As explained in the Court’s order on defendants’ motion to dismiss, there were
originally five Cook defendants in this action: (1) Cook Inc.; (2) Cook Medical; (3) Cook
Group, Inc.; (4) Cook Medical Holdings LLC; and (5) Cook Medical Technologies LLC. 
The Court granted defendants’ motion to dismiss the latter three defendants for lack of
personal jurisdiction.  ECF No. 290.                                      
                              -2-                                        
in any event, the Estate’s contract claims fail for lack of consideration and other reasons. 
Cook further argues that the Amplatz name has become generic or descriptive and

therefore is freely available for the public to use.  Cook counterclaims against the Estate
for unjust enrichment and breach of contract, seeking a return of royalty payments that
it made to Amplatz after the contracts allegedly expired.                 

    This matter is before the Court on Cook’s motion for summary judgment and the
Estate’s motion for partial summary judgment.  Cook seeks judgment in its favor both
on the Estate’s claims against it and on its counterclaim against the Estate for unjust
enrichment.  The Estate, for its part, moves for summary judgment on a portion of its

breach-of-contract claim against Cook and for summary judgment on all of Cook’s
counterclaims against it.                                                 
    For the reasons that follow, both motions are granted in part and denied in part. 

Specifically, the Court (1) grants Cook’s motion for summary judgment as to the
Estate’s claims for promissory estoppel and unfair competition; (2) grants the Estate’s
motion for summary judgment on all of Cook’s counterclaims; and (3) grants summary
judgment to the Estate and against Cook on the issue of whether Amplatz waived or

abandoned his right to control the commercial use of his name.  The parties’ motions are
denied in all other respects.

    The original parties to the 1983 contract were Amplatz and Cook Inc.  Whetham

Dep. 232 [ECF No. 201-1].  Under the 1983 contract, Cook Inc. agreed to pay annual
royalties to Amplatz for a limited term based on sales of four products that Amplatz
had helped to develop and that were identified in the contract.  ECF No. 277-2 at 5–6.3 

The contract contemplated that, “[s]hould new products be developed, they could be
added to the agreement, but they would have different ending dates for the term of
their agreement.”  Id. at 5.                                              
    The original parties to the 1995 contract were Amplatz and an entity called Cook

Urological Inc.  Whetham Dep. 232–33 [ECF No. 206-1].  Under the 1995 contract, Cook
Urological Inc. agreed to pay Amplatz semiannual royalties based on the sales of a
single product identified as the “Madduri/Amplatz Urethral Access Set.”  ECF No. 277-

2 at 4.  The contract was to continue until December 31, 2000, “at which time it shall be
reviewed and, if no changes are proposed, will be automatically renewed.”  Id.  
    Cook Urological Inc. was later folded into Cook Inc., which at that point became

a party to both the 1983 and 1995 contracts.  Whetham Dep. 233 [ECF No. 206-1]. 
Following the formation of Cook Medical Technologies LLC (“CMT”) as an intellectual-
property holding company in 2010, the Amplatz contracts were assigned to CMT, along

    Cook Inc. funded the Amplatz royalty payments up until 2017, after which those

payments were funded by CMT.  Whetham Dep. 257, 264–65 [ECF No. 206-1];   
Richardson Dep. 34 [ECF No. 277].  In some of Cook’s cover letters accompanying the
royalty payments—letters that were written long after 2000, when Cook now claims the
last of the two contracts expired—Cook referred to the parties’ “contract” and otherwise

implied that Cook regarded the 1983 and 1995 contracts as remaining in effect.  Irie
Dep. 57 [ECF 206-2]; ECF No. 277-5 (2012 and 2014 letters from “Cook Medical” to

“year of the contract,” respectively).                                    
    In late 2019, Amplatz’s estate-planning counsel contacted Cook to ask that the
royalty payments be made to a trust instead of to Amplatz personally.  Whetham
Dep. 78–79, 81–82, 106–07 [ECF No. 206].  Cook was prepared to approve the change,

    4As noted, Cook contends that the Amplatz contracts were no longer in force by
the time CMT was formed.  Viewing the record in the light most favorable to the Estate,
however, the Court finds that there is sufficient evidence for a jury to find that the 1983
and 1995 contracts were still in force and therefore were assigned to CMT.

died.  After learning of Amplatz’s death and consulting with outside counsel, Cook
decided to terminate the royalty payments.  Whetham Dep. 91, 253–54 [ECF Nos. 206,

206-1].  Even though Cook’s original position seemed to be that Amplatz was entitled to
royalty payments until the end of his life, Cook refused to pay Amplatz royalties for the
months preceding his death in late 2019.  Irie Dep. 86–87, 108 [ECF No. 206-2]; Whetham

Dep. 82, 111, 191–92 [ECF Nos. 206, 206-1].

                       B.  The Estate’s Claims                           
               1.  Contract and Related Claims (Counts 1–5)              

    Cook moves for summary judgment on the Estate’s contract claims (Counts 1
and 2) and on the Estate’s alternative claims for unjust enrichment and breach of the
covenant of good faith and fair dealing.5  The Estate moves for partial summary

judgment in its favor, seeking a ruling that the royalty contracts were in force through
2019—or, in the alternative, at least through the date of Amplatz’s death—and
awarding the Amplatz estate the corresponding amount of royalties.  The Court denies
both parties’ motions on these claims.                                    

    As the Court explained in its order on Cook’s motion to dismiss, there is ample
evidence that the parties had one or more implied-in-fact contracts at least through the
date of Amplatz’s death.  But the terms and exact duration of that contract or contracts

are disputed factual issues that must be resolved by a jury.  For that reason, all
arguments that depend on the duration or terms of the contracts—such as arguments
that Cook terminated the contracts, or that the contracts terminated upon Amplatz’s



    5The Estate has withdrawn its claims for promissory estoppel and unfair
competition.  See ECF No. 310 at 28.  Accordingly, the Court treats Cook’s motion for
summary judgment on those claims as unopposed and grants it.  See Fed. R. Civ.
P. 41(a)(2) (“Except as provided in Rule 41(a)(1), an action may be dismissed at the
plaintiff’s request only by court order, on terms that the court considers proper.”).

death, or that the contracts survived Amplatz’s death—will have to be resolved by a
jury.                                                                     

    Cook argues that, even if the contracts still exist, Cook Inc. and Cook Medical are
not parties to the contracts, as Cook Inc. assigned the contracts to non-party CMT in
2010.  Cook points to no evidence that Amplatz ever consented to this assignment,

however.  As a result, Cook Inc. remains responsible for performing its duties under the
contracts, whether or not it assigned the contracts to CMT.  See Epland v. Meade Ins.
Agency Assocs., Inc., 
564 N.W.2d 203, 207
 (Minn. 1997) (“A party may not divest itself of

liability on a contract without the consent of the other party to the contract.”); Vetter v.
Sec. Cont’l Ins. Co., 
567 N.W.2d 516, 521
 (Minn. 1997) (“the original obligor may not
divest itself of liability without the consent of the obligee”); Tony & Leo, Inc. v. U.S. Fid.
& Guar. Co., 
281 N.W.2d 862, 865
 (Minn. 1979) (“A mere assignment does not absolve

the assignor of its obligations under a contract.”).                      
    In addition, CMT licenses the contracts back to Cook Inc. to practice.  Whetham
Dep. 230, 242, 249 [ECF No. 206-1].  As a result, even if Cook Inc. was somehow

divested of its contractual duties by virtue of the 2010 assignments, Cook Inc. would
nevertheless be liable on the contracts as a result of this license.  S O Designs USA, Inc. v.
Rollerblade, Inc., 
620 N.W.2d 48, 54
 (Minn. Ct. App. 2000) (explaining that a license is


                              -8-                                        
simply a form of assignment and that, as a result, either the assignee or, upon the
assignee’s failure, the assignor, were liable to pay royalties).          

    Similarly, a jury could find that either Cook Inc. or CMT impliedly granted Cook
Medical a license.  Indeed, if the jury finds that the royalty contracts still exist, the jury
will almost certainly also find that Cook Medical has a license to practice rights under

those contracts, and almost certainly find that Cook Medical is obligated to pay
royalties.  
Id.
  Alternatively, the jury could find that, through its conduct marketing
Amplatz-branded products and paying royalties to Amplatz, Cook Medical entered into
(or took over) a contract or contracts with Amplatz, the terms and duration of which

would be fact questions for the jury.                                     
    Cook next argues that the contracts fail for lack of consideration.  Specifically,
Cook argues that it received nothing of value in return for its royalty payments because

the Amplatz name had become a generic or descriptive term, and therefore lacked
economic value.  But whether the Amplatz name had become generic or       
descriptive—and, if so, whether Cook nevertheless received something of value in
return for its royalty payments—are jury issues, and Cook is therefore not entitled to

summary judgment on this ground.  Cf. Ford Motor Co. v. Summit Motor Prods., Inc., 
930 F.2d 277
, 292 n.18 (3d Cir. 1991) (“The characterization of a mark is a factual issue for
the jury.”).                                                              

                              -9-                                        
    Cook next contends that the alleged contract or contracts are unenforceable
under the statute of frauds.  See 
Minn. Stat. § 513.01
(1) (to be enforceable, a contract that

“by its terms is not to be performed within one year from the making thereof” must be
in writing).  Obviously, whether either alleged contract must be in writing depends on
its terms, and those terms are disputed.                                  

    Cook argues that, if the Estate is correct that royalties are contractually payable
to Amplatz’s heirs, the contracts are necessarily incapable of being performed within a
year and therefore must be in writing.  This argument is misplaced, however, as the
statute of frauds does not apply to a contract unless the contract by its terms cannot

possibly be performed within one year.  
Id.
  It does not matter whether performance
within a year is likely.  See Eklund v. Vincent Brass & Aluminum Co., 
351 N.W.2d 371, 375
(Minn. Ct. App. 1984) (“The test is simply whether the contract by its terms is capable of

full performance within a year, not whether such occurrence is likely.” (citation
omitted)).  Accordingly, when the length of a contract is measured by a lifetime (or
lifetimes), the contract is capable of performance within a year (because the relevant life

could end at any moment), and the statute of frauds therefore does not apply.  See 
id.
at 375–76 (holding that a contract for permanent employment until retirement was
capable of performance within a year because, among other things, the employee could


                              -10-                                       
have died within the year).  Cook is not entitled to summary judgment on the basis of
the statute of frauds.                                                    

    Finally, the Court denies Cook’s motion for summary judgment as to the Estate’s
alternative claims for unjust enrichment and breach of the duty of good faith and fair
dealing.  Cook argues that the Estate’s unjust-enrichment claim fails because the

Amplatz name had become generic or descriptive and therefore had no economic value. 
Again, though, this is a disputed issue of fact.  Cook also argues that the unjust-
enrichment claim fails because an “adequate legal remedy” exists and contends that this
is true “even when a plaintiff’s legal claims lack merit,” citing Loftness Specialized Farm

Equipment, Inc. v. Twiestmeyer, 
742 F.3d 845, 854
 (8th Cir. 2014).  See ECF No. 296 at 27. 
In Loftness, however, the unjust-enrichment claim failed because the parties’ relationship
was governed by contracts.  
Id.
 at 854–55 (“Having struck this deal, Twiestmeyer, Hood,

and T & A cannot rewrite it via unjust enrichment.”).  Here, however, the existence of a
contract is in dispute, and the Estate can therefore pursue its claim of unjust enrichment
in the alternative.                                                       

    As for the duty of good faith and fair dealing, Cook’s only argument is that,
because the parties have no enforceable contract, there can be no implied contractual
duty of good faith.  Again, however, the existence of a contract between the parties is a
disputed factual issue.                                                   

                              -11-                                       
                         2.  Right of Publicity                           
     Cook also moves for summary judgment on the Estate’s claim for violation of

Amplatz’s right of publicity.  See Ventura v. Titan Sports, Inc., 
65 F.3d 725, 730
 (8th Cir.
1995) (“We believe that the Minnesota Supreme Court would recognize the tort of
violation of publicity rights.”); Paisley Park Enters., Inc. v. Boxill, 
299 F. Supp. 3d 1074, 1084
 (D. Minn. 2017) (“The right of publicity under Minnesota common law is
descendible and enforceable by the decedent’s estate.”).                  
                          a.  Abandonment                                 

     Cook first argues that Amplatz had no protectable right of publicity because he
waived or abandoned his right to control the use of his name for commercial purposes. 
Cook points to evidence that, in 1999, Boston Scientific notified Amplatz that it would
no longer pay him royalties, but would nevertheless continue to use his name to sell

products.  Defts.’ Ex. 4.  Cook also cites other examples of companies who apparently
use the Amplatz name for commercial purposes without paying royalties.  Cook
compares the right of publicity to a trademark, which an owner can abandon through

acts of omission (as well as commission) that cause the mark to lose its significance as a
mark.  See 
Minn. Stat. § 333.18
, subd. 6(2).                              
    The right of publicity certainly bears some similarity to trademark law, but the
Court does not agree that the concept of abandonment should apply in this context. 

                               -12-                                       
“One’s birth name is an integral part of one’s identity; it is not bestowed for commercial
purposes, nor is it ‘kept alive’ through commercial use.”  Abdul-Jabbar v. Gen. Motors

Corp., 
85 F.3d 407, 411
 (9th Cir. 1996); cf. Price v. Hal Roach Studios, Inc., 
400 F. Supp. 836, 846
 (S.D.N.Y. 1975) (characterizing as “nonsensical” the argument that, through non-use,
a person could lose rights in his own name and likeness), abrogated on other grounds by

Pirone v. MacMillan, Inc., 
894 F.2d 579
, 585–86 (2d Cir. 1990) (recognizing that New York
courts have held that the only right of publicity under New York law is statutory). 
Consequently, “[a] proper name . . . cannot be deemed ‘abandoned’ throughout its

possessor’s life, despite his failure to use it, or continue to use it, commercially.”  Abdul-
Jabbar, 
85 F.3d at 411
.                                                    
    The Court agrees with this analysis and finds it equally applicable to Cook’s
argument that Amplatz waived or abandoned his right to control the commercial use of

his name by failing to enforce that right against Boston Scientific and other companies. 
The Court holds that, under Minnesota law, an individual’s right to control the
commercial use of his or her name cannot be abandoned or waived by omission—that is,

by a failure to enforce—at least during that individual’s lifetime.        
                     b.  Generic or Descriptive Term                      
    Cook next argues that, by 2019, the name “Amplatz” had become a generic or
descriptive term to which Amplatz no longer had an exclusive right.  Cf. 2 McCarthy on

                               -13-                                       
Trademarks and Unfair Competition § 13:24 (5th ed.) (“A personal name, even though
originally used as a valid mark, may, through public usage, become a generic

designation for a genus of goods.  As such, a generic personal name designation is in the
public domain and free for all to use.”).                                  
    Whether this defense should apply to a right-of-publicity claim is a difficult legal

question.  Rather than resolving that question now, the Court will wait until a jury
decides the factual issue of whether “Amplatz” has, in fact, become generic or
descriptive.  Cf. Ford Motor Co., 930 F.2d at 292 n.18 (“The characterization of a mark is a
factual issue for the jury.”).  If Cook succeeds in persuading the jury that “Amplatz” has

become generic or descriptive, cf. Murphy Door Bed Co. v. Interior Sleep Sys., Inc., 
874 F.2d 95
, 101 (2d Cir. 1989) (placing the burden of proof on the defendant to show that the
public expropriated a name and rendered it generic), then the Court will decide whether

“genericization” is a valid defense to a right-of-publicity claim.  Cook’s motion for
summary judgment is therefore denied as to the Estate’s right-of-publicity claim.
                        3.  Punitive Damages                              

    Finally, Cook moves for summary judgment on the Estate’s claim for punitive
damages.  Factual issues preclude summary judgment on this claim, however, and
Cook’s motion is therefore denied.                                         


                               -14-                                       
                          C.  Cook’s Claims                               
    As noted, Cook brings counterclaims for unjust enrichment and breach of

contract.  The Estate moves for summary judgment on both claims, and Cook seeks
summary judgment in its favor on its unjust-enrichment claim.              
                       1.  Statute of Limitations                         

    The Court agrees with the Estate that both of Cook’s counterclaims are barred by
Minn. Stat. § 524.3-803
(a), which imposes a limitations period for claims against an
estate.  Specifically, § 524.3-803(a) provides that a claim against a decedent’s estate that
arose before the decedent’s death is time-barred unless presented as follows:

         (1) in the case of a creditor who is only entitled, under the    
         United States Constitution and under the Minnesota               
         Constitution, to notice by publication under section 524.3-801,  
         within four months after the date of the court administrator’s   
         notice to creditors which is subsequently published pursuant     
         to section 524.3-801;                                            
         (2) in the case of a creditor who was served with notice under   
         section 524.3-801(c), within the later to expire of four months  
         after the date of the first publication of notice to creditors or
         one month after the service;                                     
         (3) within one year after the decedent’s death, whether or not   
         notice to creditors has been published or served under section   
         524.3-801.  Claims authorized by section 246.53, 256B.15, or     
         256D.16 must not be barred after one year as provided in this    
         clause.                                                          
Id.                                                                        
                               -15-                                       
     The parties appear to agree that subsection (a)(3) is the relevant provision in this
case.  As Cook first brought a counterclaim on December 6, 2021, and as that was more

than two years after Amplatz’s death, Cook’s counterclaims are barred under the
statute.6  See ECF No. 6.                                                  
    Cook makes a number of arguments to the contrary, all of them unavailing:  

                           a.  Jurisdiction                               
    Citing Marshall v. Marshall, 
547 U.S. 293
 (2006), Cook first argues that the “probate
exception” to federal-court jurisdiction bars this Court from applying 
Minn. Stat. § 524.3
-

803.  According to Cook, the Court is required to adjudicate the merits of its unjust-
enrichment claim without regard to the applicability of § 524.3-803.  If Cook prevails,
says Cook, it can then present its claim to the probate court, at which point the Estate can
raise its statute-of-limitations defense to that claim.                    

    This procedure would make no sense, and, not surprisingly, nothing in Marshall
requires it.  To the contrary, Marshall emphasized that the probate exception is quite
narrow and only precludes federal courts from (1) probating or annulling a will,

(2) administering a decedent’s estate, and (3) interfering with a probate court’s exercise
of in rem jurisdiction over a res.  Marshall, 547 U.S. at 311–12 (“Thus, the probate

     6Notably, Cook initially counterclaimed only for unjust enrichment.  See ECF
No. 6.  Cook did not bring its breach-of-contract claim until April 2023, about three-and-
a-half years after Amplatz’s death.                                       
                               -16-                                       
exception reserves to state probate courts the probate or annulment of a will and the
administration of a decedent’s estate; it also precludes federal courts from endeavoring

to dispose of property that is in the custody of a state probate court.”); Kiddie v. Copeland,
741 F. App’x 355
, 356 (8th Cir. 2018) (per curiam) (“The probate exception only applies to
three types of cases: the probate or annulment of a will, the administration of a

decedent’s estate, and the exercise of in rem jurisdiction over property already asserted
within the in res jurisdiction of a state court.”).                        
    Consequently, “if the plaintiff seeks an in personam judgment against the

defendant and not a res in the custody of a state court, the federal district court may
properly adjudicate the claim.”  McAninch v. Wintermute, 
491 F.3d 759, 766
 (8th Cir. 2007)
(cleaned up); see also Kiddie, 741 F. App’x at 356 (“Seeking an in personam judgment
against a person for their conduct with property that ultimately became estate property

is not within the probate exception to federal jurisdiction.”).  That is exactly the situation
here with respect to Cook’s claims against the Estate.                     
    This Court has subject-matter jurisdiction over Cook’s claims.  It would be

exceedingly strange if this Court could exercise that subject-matter jurisdiction to resolve
everything about Cook’s claims—substantively and procedurally—except the question
of whether the claims are timely under state law.  The application of § 524.3-803 does not
implicate any of the exceptions to federal jurisdiction, and Cook cites to no case holding

                               -17-                                       
that a federal court can adjudicate everything about a claim against an estate except the
application of the statute of limitations.  The Court therefore rejects Cook’s argument

that the Court lacks jurisdiction to apply § 524.3-803.                    
                            b.  Peterson                                  
    Cook next argues that, under Peterson v. Marston, 
362 N.W.2d 309
 (Minn. 1985), its

communications with the Estate’s attorneys in February and March 2020 qualify as 
presentation of a timely claim against the Estate.  The Court disagrees.   
    Peterson addressed what is necessary to “present” a claim against an estate within

the meaning of 
Minn. Stat. § 524.3-804
 (“Manner of presentation of claims”).  Section
524.3-804 authorizes two types of presentment: (1) delivering to the personal
representative or filing with the court administrator “a written statement of the claim
indicating its basis, the name and address of the claimant, and the amount claimed,” or

(2) commencing “a proceeding against the personal representative in any court where
the personal representative may be subjected to jurisdiction . . . within the time limited
for presenting the claim.”                                                 

    In Peterson, the Minnesota Supreme Court held that a letter inquiring about the
status of a contract for deed sent to an attorney for an estate qualified as a written
statement of a claim under § 524.3-804.  Peterson, 
362 N.W.2d at 313
.  The court focused
on whether the letter communicated a present intent to make a claim.  
Id.
 at 312

                               -18-                                       
(discussing whether the language of the letter showed a “present intent to make a
claim”).  The court held that the letter communicated such an intent, as (1) the letter was

sent in response to a published notice about how to make claims against the estate;
(2) the letter was sent to the estate attorney identified in the published notice; (3) the
claimants mentioned the contract for deed and stated that they understood that they

needed to present their claim against the estate within four months; and (4) the claimants
asked if their contract would be affected and whether “any action is necessary.”  
Id.
 at
312–13.                                                                    
    In contrast to Peterson, Cook’s February and March 2020 correspondence with the

estate attorneys does not demonstrate a present intent to make a claim.  To the contrary,
the final email from Cook to the Estate’s attorneys states that “Cook is currently
weighing its options with respect to these [royalty] payments, none of which should

have ever been made.”  Defs.’ Ex. 30 (March 16, 2020 email).  A statement that a party is
“weighing its options” is not a demand or assertion of a right to payment.  Peterson, 
362 N.W.2d at 312
 (“A claim is a demand, an assertion of the right to payment.”).  

    The very different context of the correspondence in Peterson underscores the
Court’s conclusion.  Peterson involved an undisputed contract under which the claimants
obviously expected—and were contractually entitled to—ongoing payments.  Here, by
contrast, in the months after Amplatz’s death, what eventually became the parties’

                               -19-                                       
dispute over the nature of the Amplatz/Cook relationship and the basis for the many
years of royalty payments that Cook had made to Amplatz was just beginning to take

shape.  In light of that context, Cook’s correspondence is plainly not “evidence of present
intent to make a claim.”  
Id.
                                              
    There are a couple of additional reasons why Cook’s correspondence fails to

satisfy 
Minn. Stat. § 524.3
-804—which, again, requires “a written statement of the claim
indicating its basis, the name and address of the claimant, and the amount claimed.” 
Cook has been careful, throughout these proceedings, to insist that the separate
corporate identities of the various Cook entities be scrupulously respected.7  In the

correspondence on which it relies, however, Cook’s attorneys repeatedly refer to the
Cook entities as a group.  See Defts.’ Exs. 28–30.  Consequently, the “name . . . of the
claimant” is not clear from this correspondence.                           

    The “amount claimed” is even less clear.  Peterson involved a contract for deed
requiring the decedent to make payments in specific amounts on specific dates.  Peterson,
362 N.W.2d at 313
.  The estate attorney was familiar with the contract, as his firm had

drafted it, he had notarized it, and he was generally aware of its contents.  
Id.
 (“Because
of his familiarity with the contract, specific mention of the amount due was not
necessary; [the estate attorney’s] familiarity with and access to the contract constituted

     7“Cook” is merely the shorthand that the Court has used to refer to the two
remaining defendants in order to improve the readability of this order.   
                               -20-                                       
notice of the amount claimed.”).  Here, by contrast, the parties’ correspondence
demonstrates that the estate attorneys were unfamiliar with the nature of the

Amplatz/Cook contractual relationship.  Indeed, most of the exchange between the
estate attorneys and Cook’s attorneys involved the estate attorneys trying to get the
information they needed to figure out the nature of the Amplatz/Cook relationship. 

Obviously, then, those attorneys would have no idea how to calculate the amount of any
claim that Cook might assert.                                              
    True, Cook’s emails mention certain dollar amounts.  See Defts.’ Ex. 30 (March 16,
2020, email mentioning that “in the period 2006–2018 alone Cook paid more than $5.5

million to Dr. Amplatz . . . even though Cook had no legal or contractual obligation to do
so”).  But nowhere does Cook identify the amount of any claim against the estate.  To the
contrary, the emails make clear that the dollar amounts they mention are not the total

value of any claim that one or more of the Cook companies might assert against the
Estate.  See ECF No. 291 at 30 ¶ 18 (unjust-enrichment claim for payments Cook made to
Amplatz “[f]rom 2000 to at least August 2019”); 
id.
 at 31–32 ¶ 29 (breach-of-contract

claim for payments made “for at least the years 2015–2018”).               
    For all of these reasons, Cook’s February and March 2020 correspondence does
not constitute a “claim” for purposes of § 524.3-804 and Peterson.         


                               -21-                                       
                    c.  
Minn. Stat. § 524.3-803
(c)(4)(ii)                 
    Cook next contends that the Court should allow its claim under 
Minn. Stat. § 524.3-803
(c)(4)(ii).  That provision authorizes a court to permit a late claim “for cause
shown.”  To establish cause, a claimant must establish a “significant reason” for the
delay.  In re Est. of Kotowski, 
704 N.W.2d 522, 531
 (Minn. Ct. App. 2005).  “A petition for a

late claim may be granted in cases of ‘hardship, misunderstanding, and diligent but
mistaken procedures’ but not in cases of ‘unexplained and inexcusable lack of
diligence.’”  
Id.
 (quoting In re Est. of Thompson, 
484 N.W.2d 258
, 261–62 (Minn. Ct. App.

1992)).                                                                    
    Cook argues that it has established cause because it did not receive notice under
Minn. Stat. § 524.3-801
.  As Cook acknowledges, however, the one-year statute of
limitations applies regardless of whether the creditor received notice.  See 
Minn. Stat. § 524.3-803
(a)(3) (claims must be brought “within one year after the decedent’s death,
whether or not notice to creditors has been published or served under section
524.3-801”).  More importantly, Cook learned of Amplatz’s death within just a few

weeks after it occurred.  Whetham Dep. 111–12 [ECF No. 206].  Yet Cook did not assert a
claim against Amplatz’s estate until December 6, 2021, more than two years later.  ECF
No. 6.  As Cook failed to act diligently, the Court will not excuse its late presentation.


                               -22-                                       
    In sum, the Court grants the Estate’s motion for summary judgment on Cook’s
counterclaims for unjust enrichment and breach of contract because those claims are

barred by the statute of limitations.                                      
                          2.  Recoupment                                  
    Finally, Cook argues that, even if its unjust-enrichment claim is time-barred, that

claim may nevertheless serve as a recoupment defense.  See Household Fin. Corp. v. Pugh,
288 N.W.2d 701, 703
 (Minn. 1980) (“a defense in the nature of recoupment is generally
permitted even though the applicable statute of limitations would have barred an
independent action on the same claim”).  A claim for recoupment “must arise out of the

same transaction that is the subject matter of the plaintiff’s action and it can only be
utilized to reduce or avoid the plaintiff’s recovery.”  
Id. at 704
.        
    The Court does not understand how the Estate could recover on any of its claims

against Cook and yet also be found liable to Cook for unjust enrichment.  If the Estate
recovers on it contract claims, Cook would be precluded from recouping anything on an
unjust-enrichment theory.  See Graff v. Brighthouse Life Ins. Co., 
109 F.4th 1118, 1124
 (8th

Cir. 2024) (“Under Minnesota law, equitable remedies, including recovery under a
theory of unjust enrichment, ‘cannot be granted where the rights of the parties are
governed by a valid contract.’” (quoting Loftness, 
742 F.3d at 854
)).  If the Estate recovers
on its own unjust-enrichment claim, it is hard to imagine how Amplatz could also have

                               -23-                                       
been unjustly enriched by Cook so as to reduce the Estate’s recovery.  And finally, if the
Estate recovers on its right-of-publicity claim, then Cook never had the right to use the

Amplatz name for free, and the requirement that it pay Amplatz for using his name
would not be “unjust.”                                                     
    Setting this aside, Cook’s unjust-enrichment claim fails on the merits.  “Unjust

enrichment is an equitable doctrine that allows a plaintiff to recover a benefit conferred
upon a defendant when retention of the benefit is not legally justifiable.”  Caldas v.
Affordable Granite & Stone, Inc., 
820 N.W.2d 826, 838
 (Minn. 2012), superseded by statute on

other grounds as stated in Hall v. City of Plainview, 
954 N.W.2d 254
, 270 (Minn. 2021). 
“[U]njust enrichment claims do not lie simply because one party benefits from the efforts
or obligations of others . . . .”  First Nat’l Bank of St. Paul v. Ramier, 
311 N.W.2d 502, 504
(Minn. 1981).  “[T]he plaintiff must show that the defendant was enriched illegally or

unlawfully, or in a manner that is morally wrong.”  Herlache v. Rucks, 
990 N.W.2d 443
,
450 (Minn. 2023) (cleaned up).  “[U]njust enrichment should not be invoked merely
because a party has made a bad bargain.”  Cady v. Bush, 
166 N.W.2d 358, 362
 (Minn.

1969).                                                                     
    Applying these principles, no reasonable factfinder could conclude that Amplatz
was unjustly enriched by the royalty payments he received from Cook.  The undisputed
evidence establishes that, despite the expiration terms in the written contracts to which it

                               -24-                                       
now points, Cook knowingly and deliberately chose to continue making royalty
payments to Amplatz, including for new products that Cook knew were not covered by

the written contracts.  Cook (1) paid royalties on a regular basis for nearly 20 years after it
now claims that it no longer was contractually obligated to do so; (2) characterized the
royalty payments as being pursuant to a contract in its communications with Amplatz;

and (3) put each royalty payment through layers of review, including by a manager and
a corporate officer.  Richardson Dep. 32, 36–42, 89–90 [ECF No. 277].      
    Even when a Cook employee raised questions about the royalty payments, Cook
insisted on continuing to make them.  Ryan Dep. 29–30, 45–48, 78, 155 [ECF No. 206-3]

(employee was told to “leave it alone” and later remarked to an employee in the
accounting department that the payments were “untouchable until death”).  And when
an issue arose regarding payments to Frank Kotula, a colleague of Amplatz with whom

Amplatz split his Cook royalties, Cook (through its general counsel) took the position
that Kotula was entitled to payments through the end of his life.  ECF No. 315-9; ECF
No. 277-2 at 5.  Cook has no coherent explanation for why Kotula, but not Amplatz,

would be entitled to payments until the end of his life.                   
    All of this evidence establishes beyond any doubt that Cook make a deliberate
decision to continue to make the royalty payments until 2019.  There is, however, no
competent evidence as to why Cook decided to do so.  Cook contends that it was paying

                               -25-                                       
royalties, not because it was contractually bound, but because it made a “business
decision” to do so in the belief that there was economic value in Amplatz’s name.  But

when the Court pressed Cook on this assertion, Cook was unable to cite any evidence
concerning who made the “business decision” to continue paying royalties, much less
why that “business decision” was made.8  ECF No. 340 at 44–54; Ryan Dep. 15–16, 31

[ECF No. 315] (Cook cannot identify who made the alleged business decision); Whetham
Dep. 85 [ECF No. 298-4] (Cook does not know who made the decision).  Instead, Cook
just kept repeating the mantra that at some (unidentified) point some (unidentified)
person made a “business decision” for some (unidentified) reason to continue to pay

royalties to Amplatz.                                                      


     8Cook contends that a written Cook policy dating from the 1980s demonstrates
that Cook would pay royalties for the use of a physician’s name even in the absence of a
contract.  See ECF No. 321 at 7; Defts.’ Ex. 21 ¶ 7.                      
     There are two problems with Cook’s argument.  First, the policy says no such
thing.  The policy is entitled “Policy on Royalty Agreements” and is clearly discussing
contractual relationships; the final paragraph, to which Cook points, begins by stating
that “[i]f COOK INCORPORATED and the inventor-developer arrive at an      
agreement . . . .”  Defts.’ Ex. 21 ¶ 7.  Nowhere does the policy mention making
payments in the absence of a contract.  Second, because there is no evidence concerning
who made the alleged business decision, there is also no evidence that he or she knew
of or was following this policy, or even that the policy was in effect at the unknown
time that the decision was made.  (Notably, the cover letter accompanying the policy
stated that “[t]his policy [is] certainly not to be considered the only way that we could
come to an agreement with a developer . . . .”  Defts.’ Ex. 21.)          
                               -26-                                       
    This will not do.  Corporate employees typically do not make a “business
decision” to pay for nothing.  Without any evidence as to why Cook made the “business

decision” to continue to pay royalties, Cook cannot show that anything unjust occurred. 
Indeed, the sparse evidence in the record suggests that Cook decided to continue the
royalty payments on account of its long and close relationship with Amplatz and

because it was continuing to benefit from that relationship.  Ryan Dep. 15 [ECF No. 315]
(testifying that Cook continued paying royalties both because of the belief that the
Amplatz name was valuable and because of the parties’ relationship); Whetham Dep.
108 [ECF No. 206] (discussing email referring to Amplatz’s lengthy relationship with the

“Cook family”).                                                            
    Cook complains that Amplatz never informed it that other medical-device
companies were using Amplatz’s name without compensating him.  Again, because

there is no evidence as to why Cook continued paying royalties, there is also no evidence
that such information would have made any difference to Cook.9  Setting that aside,

     9Cook points out that the 1995 contract granted Cook “the exclusive right to use
[Amplatz’s] name in the descriptive title of the stated product,” as well as the exclusive
right to manufacture that product.  ECF No. 313 at 4.  The “stated product” in the 1995
contract was discontinued in 2002, however, and Cook does not point to anything that
would give rise to an implied exclusivity provision as to other products.  Id.; Ryan Dep.
67–69 [ECF No. 315].  Indeed, any such implication is severely undermined by the fact
that the parties clearly knew how to agree on exclusivity, yet chose not to do so in the
1983 contract, which covered more products than the 1995 contract.        
                                                       (continued...)     
                               -27-                                       
nothing in the parties’ written contracts required Amplatz to prevent other medical-
device companies from using his name or to inform Cook how much (if anything) he

was being paid by other companies who used his name.  Nor has Cook pointed to
anything in the parties’ subsequent course of dealing that would have given Amplatz
any idea that Cook expected him to provide such information.               

    Indeed, under Cook’s version of events, Cook had no contractual or other legal
obligation to pay royalties, but nevertheless made a “business decision” to continue to
pay money that it was not obligated to pay.  Again, its argument that it would have
made a different “business decision” if it had learned that other companies were (legally

or illegally) using the Amplatz name without paying for a license falters on the fact that
there is no evidence explaining why Cook continued to make payments.  Setting that
aside, if Cook’s account is accurate, then Cook believed that it had no legal obligation to

pay Amplatz but decided to do so anyway.  Ryan Dep. 22 [ECF No. 315].  If Cook

    9(...continued)                                                       
     Moreover, the 1995 contract did not impose a duty on Amplatz to police others’
use of his name, which is something that Cook could have done as easily as Amplatz. 
See Restatement (Third) of Unfair Competition § 46 (1995) (“[W]hen the license is
exclusive, courts have held that the licensee has standing to object to commercial uses
that infringe on the scope of the licensee’s exclusive right”); Hillerich & Bradsby Co. v.
Christian Bros., 
943 F. Supp. 1136, 1138
 (D. Minn. 1996) (granting exclusive licensee’s
motion for a preliminary injunction against competitor’s use of player’s name on sports
equipment).  The Court thus sees little basis for implying an exclusivity provision in the
parties’ relationship, and particularly not such a provision that imposes duties on
Amplatz that were not imposed under the written terms of the 1983 and 1995 contracts.
                               -28-                                       
believed that it had no legal obligation to pay Amplatz, Cook can hardly complain that
other companies reached the same conclusion, or that Amplatz did not attempt to

prevent other companies from using his name.  In short, even under Cook’s version of
events, there is nothing unjust about Amplatz retaining the royalty payments.  
    For these reasons, the Court grants the Estate’s motion for summary judgment on

Cook’s recoupment defense.10                                               

ORDER

    Based on the foregoing, and on all of the files, records, and proceedings herein, IT
IS HEREBY ORDERED THAT:                                                    

    1.   Defendants’ motion for summary judgment [ECF No. 294] is GRANTED 
         IN PART and DENIED IN PART.                                      
         a.   The motion is GRANTED as to plaintiff’s claims of promissory

              estoppel and unfair competition.                            
         b.   The motion is DENIED in all other respects.                 
    2.   Plaintiff’s motion for partial summary judgment [ECF No. 308] is 
         GRANTED IN PART and DENIED IN PART.                              

         a.   The motion is GRANTED as to:                                

     10Cook does not contend that its counterclaim for breach of contract would entitle
it to recoupment.  See ECF No. 321 at 19.  The Court therefore grants summary
judgment as to the entirety of Cook’s recoupment defense.                 
                               -29-                                       
                i.      Defendants’ counterclaims for unjust enrichment and breach 
                      of contract. 
                ii.     Defendants’ waiver and abandonment defenses to plaintiff's 
                      right-of-publicity claim.
