Cacace v. Meyer Marketing (Macau Commercial Offshore) Co.
Cacace v. Meyer Marketing (Macau Commercial Offshore) Co.
Opinion of the Court
OPINION AND ORDER
Plaintiffs Chris Cacace (“Cacace”) and Culinary Edge Creations, LLC (“CEC”) (collectively, “Plaintiffs”) bring this patent infringement action against Defendants Meyer Corporation, U.S. (“Meyer U.S.”) and its affiliate, Meyer Marketing (Macau Commercial Offshore) Co., Ltd. (“Meyer Macau”) (collectively, “Meyer” or “Defendants”), alleging that Defendants have infringed a patent over which Cacace claims ownership and over which CEC claims exploitation rights. The Parties have sought an opinion from the Court to construct the meaning of several claim terms in the patent. What follows is the Court’s construction of those claims. Defendants have also moved for summary judgment, asserting that Plaintiffs’ patent is invalid based on prior art that anticipates the patent’s claims. For the reasons stated herein, Defendants’ motion is denied.
I. Background
A. Facts
United States Patent No. 6,497,174 (“the '174 Patent”), entitled “Cooking Pan for Sautéing and Deglazing,” was issued to Cacace on December 24, 2002. (Pis.’ Opening Claim Construction Br. (“Pis.’ Opening Br.”) 1.) The '174 Patent is “generally directed to cookware designed to facilitate the mixing of food while cooking without utensils and with minimal spillage.” (Id.) It discloses a pan design that
Meyer continues to assert that its pans do not infringe the '174 Patent, disputing Plaintiffs’ constructions of several of the claim terms. (See Defs.’ Opening Claim Construction Br. (“Defs.’ Opening Br.”); Defs.’ Rebuttal Claim Construction Br. (“Defs.’ Rebuttal”).) The Parties’ proposed claim constructions are discussed below. Additionally, Meyer has introduced prior art, a Japanese patent application, JP 9-234157'(“the '157 reference”) to the Court, which it contends renders the '174 Patent invalid. (Pis.’ Resp. to Defs.’ Local Civil Rule 56.1 Statement of Material Facts and Pis.’ Local Civil Rule 56.1 Statement of Additional Material Facts (“Pis.’ 56.1”) ¶ 3; Defs.’ Local Civil Rule 56.1 Statement of Material Facts (“Defs.’ 56.1”) ¶ 3.) The '157 reference was published on September 9, 1997, and discloses a cooking pan consisting of a base that forms a cooking surface that is bounded by a side wall. (Pis.’ 56.1 ¶¶ 4-6; Defs.’ 56.1 ¶¶4-6.) The side wall has an inside surface which is a line having a curve, including at the top edge of the side wall opposite the handle. (Pis.’ 56.1 ¶ 13; Defs.’ 56.1 ¶ 13; Decl. of Peter I. Sanborn in Supp. of Defs.’ Mot. for Summ. J. of Invalidity of U.S. Patent No. 6,497,174 (“Sanborn Deck”) Ex. 3, at MM0000134.) The '157 reference further “depicts and describes a cooking pan where the lower portion of the side wall opposite the handle has a curvilinear profile,
B. Procedural History
Plaintiffs filed the Complaint on April 14, 2006. (Dkt. No. 1.) The Parties initially filed cross-motions for summary judgment (Dkt. Nos. 27, 38), which were both denied by the Court in Cacace I, (Dkt. No. 65). On March 12, 2010, the Parties filed claim construction statements for the disputed claim (“Claim 1”) of the '174 Patent (Dkt. Nos. 72, 73), and on April 2, 2010, the Parties filed responses to each other’s construction statements, (Dkt. Nos. 78, 80). A Markman hearing was held on February 16, 2011. On December 16, 2010, Defendants moved for summary judgment based on invalidity of the '174 Patent. (Dkt. No. 103.) Oral argument on this motion also was heard by the Court on February 16, 2011.
II. Discussion
A. Claim Construction
1. Standard of Review
“Victory in an infringement suit requires a finding that the patent claim covers the alleged infringer’s product or process, which in turn necessitates a determination of what the words in the claim mean.” Markman v. Westview Instruments, Inc., 517 U.S. 370, 374, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996) (internal quotation omitted). In Markman, the Supreme Court held that “the construction of a patent, including terms of art within its claim, is exclusively within the province of the court.” Id. at 372, 116 S.Ct. 1384. The purpose of claim construction “is neither to limit nor to broaden the claims, but to define, as a matter of law, the invention that has been patented.” Netword, LLC v. Centraal Corp., 242 F.3d 1347, 1352 (Fed.Cir. 2001).
The importance of intrinsic evidence in patent construction claims has been well established:
It is well-settled that, in interpreting an asserted claim, the court should look first to the intrinsic evidence of record, i.e., the patent itself, including the*553 claims, the specification and, if in evidence, the prosecution history. Such intrinsic evidence is the most significant source of the legally operative meaning of disputed claim language.
Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed.Cir. 1996) (internal citation omitted); accord Phillips v. AWH Corp., 415 F.3d 1303, 1314 (Fed.Cir. 2005) (en banc). “In most situations, an analysis of the intrinsic evidence alone will resolve any ambiguity in a disputed claim term.” Vitronics Corp., 90 F.3d at 1583. In fact, where the intrinsic evidence is sufficient to resolve ambiguities, “it is improper to rely on extrinsic evidence” to construe a claim. Id.
“All intrinsic evidence [of a claim] is not equal.” Interactive Gift Express, Inc. v. Compuserve Inc., 256 F.3d 1323, 1331 (Fed.Cir. 2001). The first source of a claim is the claim language itself, because “the claims of a patent define the invention to which the patentee is entitled the right to exclude.” Phillips, 415 F.3d at 1312 (internal quotations omitted); accord Vitronics Corp., 90 F.3d at 1582 (“First, we look to the words of the claims themselves, both asserted and nonasserted, to define the scope of the patented invention.”). During claim construction, a disputed term is typically given its “ordinary and customary meaning,” which is “the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Phillips, 415 F.3d at 1312-13 (internal quotation omitted). However, “a patentee may choose to be his [or her] own lexicographer and use terms in a manner other than their ordinary meaning, as long as the special definition of the term is clearly stated in the patent specification or file history.” Vitronics Corp., 90 F.3d at 1582. After the claim’s language, the court should then consider the rest of the intrinsic evidence, beginning with the specification and finishing with the prosecution history. See id. “This history contains the complete record of all the proceedings before the Patent and Trademark Office, including any express representations made by the applicant regarding the scope of the claims.” Id. In this regard, claims must be construed in the context of the entire patent, including the specification, which “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315 (internal quotation marks omitted). “The specification acts as a dictionary when it expressly defines terms used in the claims or when it defines terms by implication.” Vitronics Corp., 90 F.3d at 1582. Limitations from the specification, however, should not be read into the claims. See Phillips, 415 F.3d at 1323-24; Interactive Gift Express, 256 F.3d at 1331 (“[I]n looking to the specification to construe claim terms, care must be taken to avoid reading limitations appearing in the specification into the claims.” (alterations and internal quotation marks omitted)).
If a patent’s intrinsic evidence does not clarify the meaning of a disputed claim term, only then may a court can consider extrinsic evidence, which includes, but is not limited to, expert and inventor testimony, dictionary definitions, and learned treatises. See Vitronics Corp., 90 F.3d at 1584; Pall Corp. v. Micron Separations, Inc., 66 F.3d 1211, 1216 (Fed.Cir. 1995) (noting that courts can consider extrinsic evidence “if needed”). The court is not “barred from considering any particular sources or required to analyze sources in any specific sequence, as long as those sources are not used to contradict claim meaning that is unambiguous in light of the intrinsic evidence.” Phillips, 415 F.3d at 1324.
[B]ecause extrinsic evidence can help educate the court regarding the field of the invention and can help the court determine what a person of ordinary skill in*554 the art would understand claim terms to mean, it is permissible for the district court in its sound discretion to admit and use such evidence.
Id. at 1319. However, a court should be mindful that extrinsic evidence is “in general ... less reliable than the patent and its prosecution history in determining how to read claim terms.” Id. at 1318 (describing the court’s “considerable task of filtering the useful extrinsic evidence from the fluff’). Finally, claims should be interpreted so that they are consistent with the “fundamental purpose and significance of the invention, and in a manner consistent with and furthering the purpose of the invention.” Purdue Pharma L.P. v. Boehringer Ingelheim GmbH, 98 F.Supp.2d 362, 375 (S.D.N.Y. 2000) (alteration, citation, and internal quotation marks omitted), aff'd, 237 F.3d 1359, 1364 (Fed.Cir. 2001).
2. Analysis
The Parties dispute the proper construction of five terms in Claim 1 of the '174 patent. The Court will discuss each in turn.
a. “Curvilinear Profile”
The '174 Patent consists of 10 claims, including independent Claim 1. Claim 1 sets forth, in part, a “side wall [which] has an inside surface having a curvilinear profile in a plane that is normal to the cooking surface.” '174 Patent col. 10, 11. 63-65.
The Court accepts Defendants’ construction of this claim term and finds that the plain language of the claim implies that the inside surface of the side wall is curved along its entire length.
Defendants, on the other hand, point to language in the specification describing “a lower portion 18 of the side wall next to the cooking surface [that] rises smoothly upward and away from the cooking surface boundary.” (Defs.’ Opening Br. 10 (quoting '174 Patent col. 2, 1. 66-col. 3, 1. 1).) Defendants further point out that the patent figures are described as being “configured according to the invention,” and that the description of this “smooth” portion of the side wall is part of a “detailed description of the invention,” thus limiting the claims to that particular embodiment. (Id.) See Am. Med. Sys., Inc. v. Biolitec, Inc., 618 F.3d 1354, 1366 (Fed.Cir. 2010) (“ ‘[W]hen the preferred embodiment is described in the specification as the invention itself, the claims are not necessarily entitled to a scope broader than that embodiment.’” (quoting Chimie v. PPG Indus., Inc., 402 F.3d 1371, 1379 (Fed.Cir. 2005))). Plaintiffs, however, counter that the claims may not be limited only to disclosed embodiments absent a clear limiting disclaimer in the intrinsic record. (Pis.’ Rebuttal Br. 4 n. 3 (citing Nautilus Grp., Inc. v. Icon Health & Fitness, Inc., 82 Fed.Appx. 691, 694 (Fed.Cir. 2003) (“[A] construing court may not limit the claims to the disclosed embodiments without a clear disclaimer in the intrinsic record that limits the invention to these embodiments and nothing more.”)).) See also Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 906 (Fed.Cir. 2004) (“Even when the specification describes only a single embodiment, the claims of the patent will not be read restrictively unless the patentee has demonstrated a clear intention to limit the claim scope using words or expressions of manifest exclusion or restriction.” (internal quotation marks omitted)).
Even if the Court were to accept Plaintiffs’ position that the disclosed embodiments are not the only intended embodiment of the invention, it still finds that Defendants’ construction of this claim limitation should prevail. The term “curvilinear profile” means a profile marked by its curvature. Plaintiffs’ only argument against this interpretation is that the side wall in Figure 2 appears to have portions that are not curved. As noted above, this argument is at best misguided, if not factually incorrect. There is nothing in the intrinsic record that would suggest other
b. “Tangent”
Claim 1 of the '174 Patent discloses a pan comprising “a line drawn tangent to said curvilinear profile substantially at [the] fourth point.” '174 Patent col. 11,11.15-16. Plaintiffs’ proposed construction of the term “tangent” is “[m]aking contact at a single point or along a line,” while Defendants propose that “tangent” means “[m]eeting a curve at only one point.” (Pis.’ Opening Br. 16; Defs.’ Opening Br. 13.) Plaintiffs again rely on Figure 2 of the specification to support their argument, asserting that the side wall near the top edge appears to be straight, not curved, and that the tangent line therefore appears to be in contact with the side wall at more than one point, making Defendants’ proposed construction too restrictive. (Pis.’ Opening Br. 17.) However, as noted in the Court’s discussion of the term “curvilinear profile,” Plaintiffs’ reliance on these visual images is improper in this instance and cannot be accepted as conclusive evidence either that the pan is straight at this location of the side wall (indeed, the Court finds that it is not) or that a tangent line in fact intersects the curvilinear profile of the side wall at more than one point.
c. “Second and Third Points”
Claim 1 of the '174 Patent discloses “an upper portion of [a] side wall [which] has a top edge that rises upward from the cooking surface from second and third points on the top edge, to a fourth point on the top edge.” '174 Patent col. 11,11.10-12. Plaintiffs’ proposed construction of this claim is as follows: “The top edge of the side wall rises from two locations along the top edge of the side wall, one on each side of the first point and between the first and fourth points, to a location on the top edge of the side wall, opposite the handle.” (Pis.’ Opening Br. 12.) Defendants do not offer their own proposed construction for this element of claim 1, but rather argue that Plaintiffs’ proposed construction is over-inclusive, as it allows for an infinite number of pairs of locations (i.e., second and third points) along the top edge that rise upward to a fourth point on the top edge, which is impermissible given the specificity of the claim language. (Defs.’ Opening Br. 15-17.)
Plaintiffs argue that the claim language and the specification support their proposed claim construction. Their construction does, in fact, track the claim language closely. Further, Figure 1 of the specification clearly portrays the “two locations along the top edge of the side wall,” points P2 and P3, from which the top edge rises to the fourth point, P4, near the top of the side wall. (Pis.’ Opening Br. 13.) Plaintiffs further demonstrate that there are other pairs of points — for example, points P2a and P3a — from which the top edge also rises to the fourth point. (Id. at 14.) Defendants, however, assert that this construction essentially reads out the claim language, which specifically refers to “first,” “second,” “third,” and “fourth” points.
The second and third points described in Claim 1 are the first points at which the top edge begins to rise. However, if one were to start from these points and trace a path along the side wall up to the fourth point, one would inevitably pass other pairs of points (e.g., points P2a and P3a, P2b and P3b, and so on) from which the top edge also rises to a fourth point, because once the side wall begins to rise at points P2 and P3, it does not stop rising. In other words, between points P2 and P3 and the fourth point, P4, there are an infinite number of points from which the side wall rises, because of the very nature of the claimed invention. The claim language refers merely to the first two points from which the top edge begins to rise. Therefore, the Court finds that a proper construction of this claim is: the top edge of the side wall begins to rise from two locations along the top edge of the side wall, one on each side of the first point and between the first and fourth points, to a location on the top edge of the side wall, opposite the handle.
d. “Substantially at Said Fourth Point”
The '174 Patent discloses “a line drawn tangent to said curvilinear profile substantially at said fourth point.” '174 Patent col. 11, 11. 15-16. Plaintiffs’ proposed construction for the term “sub
The Federal Circuit has held that a claim should be held indefinite where it is “insolubly ambiguous”; however, “claims are not indefinite merely because they present a difficult task of claim construction. Instead, if the meaning of the claim is discernible, even though the task may be formidable and the conclusion may be one over which reasonable persons will disagree, [the Federal Circuit has] held the claim sufficiently clear to avoid invalidity on indefiniteness grounds.” Halliburton Energy Servs., Inc. v. M-I LLC, 514 F.3d 1244, 1249 (Fed.Cir. 2008) (alteration and internal quotation marks omitted). The standard of proving indefiniteness “is met where an accused infringer shows by clear and convincing evidence that a skilled artisan could not discern the boundaries of the claim based on the claim language, the specification, and the prosecution history, as well as [his or] her knowledge of the relevant art area.” Id. at 1249-50.
Defendants claim that the term in question “leavefs] open the question of exactly how close the tangent line should be drawn to the fourth point.” (Defs.’ Opening Br. 19.) They assert that this ambiguity in terminology, combined with a complete lack of guidance in the claim language, specification, and prosecution history, provides insufficient guidance to those skilled in the art to determine whether a product falls within the scope of the claims. (Id. at 20-22.) Defendants therefore believe that the term “substantially at said fourth point” is indefinite under 35 U.S.C. § 112, ¶ 2. The Court does not agree. As an initial matter, Figure 2 of the specification does in fact provide a standard which enables those skilled in the art to determine whether a tangent line has been drawn “substantially at said fourth point.” The locations of the fourth point, and the line tangent to the curvilinear profile of the inside surface of the side wall “substantially at said fourth point,” are clear in the patent drawings, and thus provide a sufficient guide to anyone skilled in the art to determine the proper location of the tangent line. In similar circumstances courts have upheld similar language in patent claims as not indefinite. See, e.g., Power-One, Inc. v. Artesyn Techs., Inc., 599 F.3d 1343, 1348-49 (Fed.Cir. 2010) (affirming district court’s ruling that the term “near” was not vague or subjective, especially where the specification illustrated the location of the element in question, thus “providing a standard for measuring the term”); Young v. Lumenis, Inc., 492 F.3d 1336, 1345-47 (Fed.Cir. 2007) (overturning district court’s determination that the term “near” was indefinite). Finally, Defendants offer nothing more than attorney
e. “Substantially Within the Forward Region”
The '174 Patent discloses a pan comprising an angle of between 2 and 10 degrees, formed by a line drawn tangent to the curvilinear profile (discussed above) substantially at the fourth point and a line that is normal to the cooking surface, “wherein the food pieces that are propelled upward near the side wall opposite the handle when the handle is pulled backward, are directed by the upper portion of the side wall to land substantially within the forward region of [the] cooking surface.” '174 Patent col. 11,11. 18-22. Plaintiffs do not offer any proposed construction for this limitation, arguing instead that one of ordinary skill in the art would understand both the action that is required to propel the food, and the desired result. (Pis.’ Opening Br. 20.) Defendants argue that this claim limitation is indefinite under 35 U.S.C. § 112, ¶ 2.
The Court outlined the framework for analyzing claim terms for indefiniteness under 35 U.S.C. § 112, ¶ 2 above, in Section II.A.2.d. Here, Defendants assert that the limitation is indefinite on the grounds that “the specification fails to provide a test method or objective basis for determining whether a product or process falls within the scope of the claim.” (Defs.’ Opening Br. 22.) See Honeywell Int’l, Inc. v. Int’l Trade Comm’n, 341 F.3d 1332, 1340—41 (Fed.Cir. 2003) (finding claim indefinite where the patent failed to provide guidance on the proper test to apply to confirm the existence of the claim limitation, where several tests existed, each of which produced different results). Because, Defendants argue, it is unclear how to measure whether food has landed “substantially within the forward region” of the cooking area, the limitation is indefinite.
The Court rejects Defendants’ arguments for several reasons. First, as noted above, terms of degree, such as “substantially,” do not automatically render claim terms indefinite. See Andrew Corp. v. Gabriel Elecs., Inc., 847 F.2d 819, 821-22 (Fed.Cir. 1988) (noting that terms of degree are acceptable in patent claims to the extent that they alert persons of ordinary skill in the art to what is being claimed). Second, despite Defendants’ assertions to the contrary, the specification does indeed provide sufficient guidance to a person of ordinary skill in the art to understand the scope of the claim limitation. Figure 2 of the specification clearly depicts the “forward region” of the cooking surface, denoted as “28” in the drawing. (J.A. 1.) Therefore, any argument that it is unclear where the food pieces are sup
B. Summary Judgment
1. Standard of Review
Summary judgment shall be granted where it is shown “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); see also Celotex Corp. v. Catrett, 477 U.S. 317, 322, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986) (same). “When ruling on a summary judgment motion, the district court must construe the facts in the light most favorable to the non-moving party and must resolve all ambiguities and draw all reasonable inferences against the movant.” Dall. Aerospace, Inc. v. CIS Air Corp., 352 F.3d 775, 780 (2d Cir. 2003); see also Tufariello v. Long Island R.R. Co., 458 F.3d 80, 85 (2d Cir. 2006) (noting that a court must draw all reasonable inferences in the nonmovant’s favor).
A party seeking summary judgment bears the burden of establishing that no
2. Analysis
Patents are presumed to be valid, and this presumption may be overcome only through facts supported by clear and convincing evidence. See SRAM Corp. v. AD-II Eng’g, 465 F.3d 1351, 1357 (Fed.Cir. 2006) (citing 35 U.S.C. § 282 and U.S. Surgical Corp. v. Ethicon, Inc., 103 F.3d 1554, 1563 (Fed.Cir. 1997)); see also Nextec Applications v. Brookwood Cos., 703 F.Supp.2d 390, 420 (S.D.N.Y. 2010) (noting the same). Therefore, “a moving party seeking to invalidate a patent at summary judgment must submit such clear and convincing evidence of facts underlying invalidity that no reasonable jury could find otherwise.” SRAM Corp., 465 F.3d at 1357; see also Zenith Elecs. Corp. v. PDI Commc’n Sys., Inc., 522 F.3d 1348, 1357 (Fed.Cir. 2008) (“Summary judgment [of invalidity] is proper if no reasonable jury could find that the patent is not anticipated.”); Gen. Electric Co. v. Nintendo Co., 179 F.3d 1350, 1353 (Fed.Cir. 1999) (noting that the question of invalidity may be decided on summary judgment if the record reveals no genuine dispute of material fact).
A party may show that a patent is invalid by demonstrating that it was anticipated by prior art. See 35 U.S.C. 102(b) (“A person shall be entitled to a patent unless ... the invention was patented or described in a printed publication in this or a foreign country ... more than one year prior to the date of the application for patent in the United States.”). A demonstration of anticipation “requires a showing that each element of the claim at issue, properly construed, is found in a single prior art reference.” Zenith Elecs. Corp., 522 F.3d at 1363. Therefore, in order to anticipate, “[a] prior art reference must disclose every limitation of the claimed invention,” but such disclosure may be done “either explicitly or inherently.” Telemac Cellular Corp. v. Topp Telecom, Inc., 247 F.3d 1316, 1327 (Fed.Cir. 2001). Prior art inherently discloses a claim limitation “ ‘if the prior art necessarily functions in accordance with, or includes, the claimed limitations,’ ” and inherency is a question of fact for the Court.
Here, Defendants assert that the '157 reference contains all of the claim limitations of the '174 Patent, both explicitly and inherently, and thus anticipates its teachings and renders the patent invalid.
Therefore, the Parties’ primary remaining dispute — and the one the Court will focus on here — is whether Defendants’ measurements of the angles in the '157 reference are admissible. If they are, then this would allow the Court to find that the '157 reference inherently discloses other of the claim limitations of the '174 Patent, possibly rendering the patent invalid as anticipated. The '157 reference does not explicitly disclose any angle limitations. However, Defendants have conducted their own measurements of the figures in the '157 reference, and argue that these measurements demonstrate that the angle between a line tangent to a point at the top edge of the forward side wall and a line normal to the cooking surface is between 2 and 10 degrees, the same as Angle A, and that a pan featuring this angle will inherently perform the functions claimed in the '174 Patent. (Defs.’ Mem. 21-22.) As an initial matter, then, the Court must determine whether Defendants’ measurements of the figures in the '157 reference were appropriate. The Court finds that they were not.
The law is clear that precise measurements should not be made, and should not be considered by a court, where the drawings and figures from which those measurements are derived are silent as to scale and proportion. See Nystrom v. TREX Co., 424 F.3d 1136, 1149 (Fed.Cir. 2005) (“ ‘Absent any written
Nystrom is particularly instructive here. In that case, which involved curved flooring boards, the district court found certain patent claims invalid as anticipated by a prior art reference. See Nystrom, 424 F.3d at 1148. Specifically, the district court, instead of applying the Federal Circuit’s holdings in In re Wright and Hockerson-Halberstadt — which it found inapplicable — inquired as to whether a person of ordinary skill in the art would use measurements from the prior art reference to determine the proper degree of board curvature, and answered that question in the affirmative. See id. The Federal Circuit reversed, holding that the district court erred in ignoring “[the Federal Circuit’s] disfavor in reading precise proportions into patent drawings which do not expressly provide such proportions.” Id. at 1149. Here, as in Nystrom, Defendants ask the Court to ignore Federal Circuit precedent and allow precise measurements to be applied to the '157 reference. Defendants attempt to distinguish Nystrom, noting that there, the defendant’s measurements were not directly based on the prior art figures themselves, but rather were based on computer simulations of those figures. (Defs.’ Mem. 19-20.) However, as Plaintiffs note (Pis.’ Mem. 15 n. 7), the Federal Circuit was less concerned with the use of a computer model than it was that the model was “premised on unstated assumptions in prior art patent drawings.” Nystrom, 424 F.3d at 1149.
III. Conclusion
For the foregoing reasons, the Court construes the disputed claim terms as described in this Opinion. Defendants’ motion for summary judgment is denied. The Clerk of the Court is respectfully directed to terminate the pending motion, (Dkt. No. 103).
SO ORDERED.
. For an extensive recitation of the origins of this litigation, see Cacace v. Meyer Mktg. (Macau Commercial Offshore) Co., 589 F.Supp.2d 314 (S.D.N.Y. 2008).
. The Parties dispute the meaning which should be ascribed to the term "curvilinear profile.” This term will be discussed in the claim construction section of this Opinion.
. Although Plaintiffs contend that the diagrams associated with the '157 reference depict a pan with a side wall opposite the handie that has both flat and curved regions, the language in the '157 reference leads to a different conclusion. For example, the abstract specifically states that the upper part of the side wall is "curved backward,” and the description states that “by placing an inversion part that curves backward towards the handle on the top part of the side face that is
. One such ambiguity highlighted by Plaintiffs in their Rule 56.1 Counterstatement — that it is unclear which element of the '157 reference actually constitutes the cooking surface from which to measure the angles — is not actually ambiguous. Plaintiffs concede as much in their Letter of August 26, 2010 to defense counsel (Sanborn Deck Ex. 7, at 2), noting that the diagrams in the '157 reference make clear that it is element 11a, and not element 11, that constitutes the cooking surface from which the angle measurements should be made.
. The Parlies agreed at oral argument that normal means perpendicular. (Oral Arg. Tr. ("Tr.”) 44:20-23.)
. The Court "ha[s] the authority to adopt claim constructions which have not been proposed by either [P]arty.” Kim v. ConAgra Foods, Inc., 465 F.3d 1312, 1319 (Fed.Cir. 2006) (citing Exxon Chem. Patents, Inc. v. Lubrizol Corp., 64 F.3d 1553, 1556 (Fed.Cir. 1995)); see also Exxon Chem., 64 F.3d at 1556 (noting that "the judge's task is not to decide which of the adversaries is correct[;] [(Instead, the judge must independently assess the claims, the specification, and if necessary the prosecution history, and relevant extrinsic evidence, and declare the meaning of the claims”).
.At oral argument, Defendants’ counsel conceded that the word "smooth” may not properly be included in a construction of this claim term, because the word "smooth” does not appear anywhere in the claim language, but rather is mentioned only in the specification, as discussed below. Therefore, the Court’s construction of the term "curvilinear profile” does not incorporate the word “smooth.” This does not, however, affect the Court’s conclusion that "curvilinear profile,” as that term is used in this patent, requires curvature along the entire length of the side wall.

The existence of “Angle A,” formed by the line tangent to the curvilinear profile substantially at the "fourth point” (which is a location on the top edge of the side wall) and a line normal to the cooking surface, further supports the fact that the inside surface of the side wall is curved near the top edge of the pan. Angle A is discussed in more detail below.
. The Court will not rely on the prosecution history to construct this term because the term was not the subject of any amendments before the United States Patent and Trademark Office ("PTO”). (Pis.’ Rebuttal Br. 5-7.) However, it should be noted that the prosecution history and the dictionary definitions of the term are not inconsistent with Defendants' construction. After the initial rejection of his patent application, Cacace filed an "Amendment” (J.A. 53-61), in order to distinguish his invention from U.S. Patent No. 6,237,470 (the "Adams prior art”), which disclosed a side wall with a substantially flat region. Unlike the original patent claims, the claims in Cacace’s Amendment described the pan's side wall as having “an inside surface having a curvilinear profile in a plane that is normal to the cooking surface.” (J.A. 54.) It is possible, therefore, to interpret the inclusion of the term "curvilinear profile” in the Amendment as intended to distinguish the side walls disclosed in Cacace’s invention from the flat side walls disclosed in the Adams prior art. Further, as Defendants note, the construction of the term "curvilinear profile” that Defendants advocate, and which the Court adopts, is consistent with several dictionary definitions of the word "curvilinear.” (Defs.’Opening Br. 11-12; see also J.A. 80 (defining "curvilinear” as "[p]ertaining to curved lines,” from McGraw-Hill Dictionary of Scientific and Technical Terms (2003)); J.A. 81 (defining "curvilinear” as "represented by a curved line,” from Merriam-Webster's Collegiate Dictionary (2004)); J.A. 82 (defining "curvilinear” as "[deviating from a straight line,” from Roget’s II The New Thesaurus (2003)).)
. Again, the Court notes that drawing definitive conclusions — especially regarding mathematical concepts such as intersection points of tangent lines, which require a high degree of precision — based on these imprecise images, is problematic.
. Defendants also argue that the prosecution history, wherein Plaintiffs amended the claims in order to overcome the Adams prior art, demonstrates that the claims specifically disclose a top edge rising to a fourth point from only one pair of points, where the slope of the top edge changes, and not multiple pairs of points. However, as Plaintiffs point out, there is no support in the record for this contention, and there is no discussion of "slope” anywhere in the patent or the prosecution history. (Pis.’ Rebuttal Br. 14-15.)
. This construction also finds support in the claim language and the specification. At oral argument, Plaintiffs' counsel stated that nothing in Claim 1 requires the top edge of the side wall to be at a uniform height between the first point, PI, and P2 and P3. (Tr. 29:19-30:6.) Indeed, Plaintiffs’ counsel is correct that this "uniform height” limitation is contained in Claim 2, and not Claim 1. However, Claim 1 would be rendered meaningless if it did not require the top edge of the side wall to have a uniform height between PI and P2/P3 because if it did not, then the claim language could potentially cover a pan that constantly rises from PI to P4, which would completely read out P2 and P3, and "claims [should be] interpreted with an eye toward giving effect to all terms in the claim.” Bicon, Inc. v. Straumann Co., 441 F.3d 945, 950 (Fed.Cir. 2006). The specification contains a visual depiction of a pan with a uniform first height between PI and P2/P3, and it contains a detailed description of the relationship between the uniform first height, "H,” of the pan between PI and P2/P3, and the height of the pan at P4, "R,” with "R” being about 1.75 times greater than "H” in the preferred embodiment. '174 Patent col. 11. 7-21. In instances "[w]here the specification makes clear that the invention does not include a particular feature, that feature is deemed to be outside the reach of the claims of the patent, even though the language of the claims, read without reference to the specification, might be considered broad enough to encompass the feature in question.” SciMed Life Sys., Inc. v. Advanced Cardiovascular Sys., Inc., 242 F.3d 1337, 1341 (Fed.Cir. 2001) (citing cases). Reading the claim language in light of the specification, and attempting to give effect to all of the claim terms, the Court is persuaded that Claim 1 includes a uniform height limitation and excludes a pan with a top edge of a side wall that rises all the way from PI to P4. Such an interpretation ensures that all of the claim terms have some meaning. Claim 2, which specifies that the pan’s height at the fourth point should be about 1.75 times the uniform height between PI and P2/P3, would not be rendered superfluous by such a reading.
. Pursuant to Federal Circuit caselaw, the Court will apply general principles of claim construction (i.e., relying primarily the intrinsic record) in analyzing the claim terms for indefiniteness. See Datamize, LLC v. Plumtree Software, Inc., 417 F.3d 1342, 1348 (Fed.Cir. 2005) ("[I]n the face of an allegation of indefiniteness, general principles of claim construction apply.”).
. Although Defendants attempt to argue that the claim limitation fails because the specification does not provide "a test method or objective basis for determining whether a product or process falls within the scope of the claim" (Defs.’ Opening Br. 22), the tests described in the '174 Patent's specification indeed provide an objective basis for determining whether a pan performs in the manner claimed by the patent. The cases cited by Defendants are distinguishable, because the patents in those cases failed to identify the criteria to be used in determining whether a product or process fell within the scope of the claims. (Pis.’ Rebuttal Br. 24-25.) Here, on the other hand, the criteria, and the test for measuring them, are provided in the patent.
. Other variables listed by Defendants, such as the level of skill of the chef, are largely irrelevant to determining whether a cooking pan is configured so that food pieces will behave in the manner described in the patent.
. The '157 reference is a Japanese laid-open patent application. (Mem. of Law in Supp. of Defs.' Mot. for Summ. J. ("Defs.' Mem.”) 5-6.) Japanese patent applications are “laid open,” or published, eighteen months after they are filed. See Brian G. Strawn, Guide to Japanese Intellectual Property Law, 26 AIPLA Q.J. 55, 66 (1998). They are treated as printed publications under United States patent law. See, e.g., Koito Mfg. Co. v. Turn-Key-Tech, LLC, 381 F.3d 1142, 1151-52 (Fed.Cir. 2004) (considering Japanese laid-open patent application as prior art in analyzing patent invalidity claim); Semiconductor Energy Lab. Co. v. Samsung Elec. Co., 204 F.3d 1368, 1372 (Fed.Cir. 2000) (noting that patentee had cited Japanese laid-open patent applications as "important prior art”). The '157 reference was filed in March 1996 and published in September 1997, and is a printed publication under 35 U.S.C. § 102(b). (Defs.’ Mem. 6 n. 2.)
. Defendants assert that Plaintiffs should be judicially estopped from arguing that measurements of patent figures lacking in information on scale or proportion are legally impermissible, because Plaintiffs overcame the Adams prior art — -which did not disclose specific dimensions or proportions — by employing such measurements. (Defs.’ Mem. 17-19.) Defendants cite New Hampshire v. Maine, 532 U.S. 742, 121 S.Ct. 1808, 149 L.Ed.2d 968 (2001), which lays out certain factors to be considered by a court when determining whether to invoke judicial estoppel. Although "the circumstances under which judicial estoppel may appropriately be invoked are probably not reducible to any general formulation of principle ... several factors typically inform the decision whether to apply the doctrine in a particular case.” Id. at 750, 121 S.Ct. 1808 (alteration, citations, and internal quotation marks omitted). These factors include: (1) whether a party's later position is "clearly inconsistent with its earlier position”; (2) "whether the party has succeeded in persuading a court to accept that party’s earlier position, so that judicial acceptance of an inconsistent position in a later proceeding would create the perception that either the first or the second court was misled”; and (3) "whether the party seeking to assert [the] inconsistent position would derive an unfair advantage or impose an unfair detriment on the opposing party if not es-topped.” Id. (internal quotation marks omitted).
Defendants contend that "[t]he only way that Mr. Cacace could have distinguished Adams ... was to calculate the 45-degree angle using the figures set forth in the patent” (Defs.’ Mem. 18), which is exactly what Plaintiffs now claim Defendants may not do. Indeed, in response to the initial PTO rejection of Plaintiffs' patent application, which referenced angle measures in the Adams prior art (where no angle measures were actually indicated), Plaintiffs responded to the PTO by re
. Compare this to the '174 Patent, which expressly includes the angle measurement in drawings in the specification. (J.A. 1.)
. Because it is only necessary for the Court to find that one claim limitation of the '174 Patent is not disclosed by the '157 reference in order to find that the '174 Patent was not anticipated, see Zenith, 522 F.3d at 1363, the Court need not, nor will it, discuss other claim limitations (Claims 7-9) that Defendants assert are anticipated by the' 157 reference. However, Claim 1, which contains the Angle A limitation, is independent, and Claims 7-9 are dependent on Claim 1. Therefore, because Defendants cannot demonstrate that the '157 reference contains each limitation of Claim 1 — namely, the Angle A limitation — and because dependent claims contain all of the limitations of the related independent claim, Defendants also fail to demonstrate that the '157 reference contains each limitation of Claims 7-9.
