Opinion
01 Communique Laboratory, Inc. ("Communique") appeals an order of the United States District Court for the Northern District of Ohio denying its motion for a new trial.
See
01 Communique Lab., Inc. v. Citrix Sys., Inc.
, No. 1:06-CV-00253,
I. BACKGROUND
Communique owns
A computer program product for use on a server computer linked to the Internet and having a static IP address, for providing access to a personal computer from a remote computer, the personal computer being linked to the Internet, its location on the Internet being defined by either (i) a dynamic public IP address (publicly addressable), or (ii) a dynamic LAN IP address (publicly unaddressable), the computer program product comprising:
(a) a computer usable medium;
(b) computer readable program code recorded or storable in the computer useable medium, the computer readable program code defining a server computer program on the server computer wherein:
(i) the server computer program is operable to enable a connection between the remote computer and the server computer; and
(ii) the server computer program includes a location facility and is responsive to a request from the remote computer to communicate with the personal computer to act as an intermediary between the personal computer and the remote computer by creating one or more communication sessions there between, said one or more communication sessions being created by the location facility, in response to receipt of the request for communication with the personal computer from the remote computer, by determining a then current location of the personal computer and creating a communication channel between the remote computer and the personal computer, the location facility being operable to create such communication channel whether the personal computer is linked to the Internet directly (with a publicly addressable) dynamic IP address or indirectly via an Internet gateway/proxy (with a publicly unaddressable dynamic LAN IP address).
In February 2006, Communique brought suit against Citrix Systems, Inc. and Citrix OnLine, LLC (collectively "Citrix"), alleging that Citrix's GoToMyPC remote computer connection service infringed independent claim 24 and dependent claim 45 of the '479 patent. J.A. 115. In March 2008, the district court stayed proceedings pending resolution of a request for
inter partes
reexamination filed by Citrix. J.A. 3021-22. Before the Patent and Trade-mark Office ("PTO"), Communique's expert, Dr. Gregory Ganger, asserted that the claims of the '479 patent differed from the prior art because they require that a "location facility" create a communication channel between the remote and personal computers. J.A. 7026;
see
01 Communique Lab., Inc. v. LogMeIn, Inc.
,
On October 29, 2013, the Patent Trial and Appeal Board confirmed the patentability of claims 24 and 45 over various prior art references, including Citrix's BuddyHelp computer connection service.
See
Citrix Sys., Inc. v. 01 Communique Lab., Inc.
, No. 2013-004565,
After the parties returned to district court, Citrix filed a motion for summary judgment, alleging that claims 24 and 45 were patent ineligible under
During claim construction proceedings, the district court construed the phrase "creating a communication channel between the remote computer and the personal computer," '479 patent, col.14 ll.8-10, to mean "making or bringing into existence a communication channel between the remote computer and the personal computer." J.A. 15 (citations and internal quotation marks omitted); see also J.A. 3242-43. The trial court denied Citrix's motion to exclude evidence pertaining to the PTO reexamination proceedings related to claims 24 and 45. J.A. 37-39. It held that the reexamination record could be used in a limited manner at trial, but that Citrix could not be identified as the party that requested the reexamination. J.A. 37. The court further ordered that the parties should "refer to the entirety of the proceedings before the PTO as the 'prosecution history.' " J.A. 38. The court determined that "it would be unfairly prejudicial to Citrix to attribute the reexamination request to Citrix or to indicate that it was Citrix that advanced certain arguments in the reexamination process." J.A. 37. The court was concerned that "[t]he jurors [might] put undue weight on the fact that it was Citrix who advanced the arguments which, in the end, were rejected by the PTO, even though the PTO does not make its decision based upon the same standard as used in an infringement/invalidity lawsuit, nor does it have the benefit of the full array of evidence that [would] be presented to a jury for its consideration." J.A. 37-38.
After the close of evidence, the trial court provided the jury with very specific instructions. ** It informed the jury that "[t]he determination of literal infringement depends on the presence of the claim elements in the accused product, not on similarities between the accused product and the prior art." J.A. 2821. It further instructed the jury that "[t]o determine literal infringement, [it] must compare the accused system, GoToMyPC, with each claim that [Communique] asserts is infringed."
*740 J.A. 2820. Additionally, the court explained that Citrix bore the burden of proving invalidity by clear and convincing evidence, J.A. 2822, 2826, and that "[t]o anticipate a claim, each and every element in the claim must be present in a single item of prior art and arranged or combined in the same way as recited in the claim," J.A. 2828.
On January 19, 2016, the jury returned a split verdict. It concluded that Citrix had not established that claims 24 and 45 were invalid, but that Communique had not established that Citrix's GoToMyPC product infringed those claims. J.A. 174-75.
After judgment was entered, Communique moved for JMOL of infringement and a new trial.
See
Fed. R. Civ. P. 50(b), 59(a). The trial court denied Communique's motion for JMOL of infringement, explaining that it had "not even mention[ed] that it sought [JMOL] on infringement in its written or oral [ Fed. R. Civ. P. 50(a) ] motions, or provide[d] any specificity regarding the law and facts supporting such a judgment."

Finjan, Inc. v. Secure Computing Corp

B. Communique's Contentions
Communique asserts that it is entitled to a new trial on the issues of infringement and damages because Citrix resorted
*741
to "a well-known defendant's trick," known as the "practicing the prior art defense." It contends that the jury verdict of non-infringement must be set aside because the trial court improperly permitted Citrix to by-pass the required comparison between the asserted claims and the accused product and instead to focus on the similarities between Citrix's current GoToMyPC product and its prior art BuddyHelp product. According to Communique, Citrix's reliance on a practicing the prior art defense "was improper, misleading, and devastatingly prejudicial to the integrity of the trial." We find this argument unpersuasive. As a preliminary matter, we reject Communique's assertion that Citrix's infringement defense eschewed the requisite limitation by limitation comparison between the asserted claims and the accused product.
See, e.g.
,
Baxter Healthcare Corp. v. Spectramed, Inc
.,
Dr. Ian Foster, Citrix's expert, described the limitations of the asserted claims, J.A. 2480-85, and then detailed how the GoToMyPC product operates, J.A. 2485-89. He concluded, based on his review of the operation of the GoToMyPC product and its source code, that it did not practice the claim limitation requiring that a "location facility ... creat[e] a communication channel between the remote computer and the personal computer," '479 patent, col.13 l.64-col.14 l.10, because in GoToMyPC "it's the host and the client that create [the] channel," J.A. 2507; see also J.A. 2495-506.
Citrix never argued that its accused product did not infringe the asserted claims merely because GoToMyPC shared the same architecture as the prior art BuddyHelp product. To the contrary, as the trial court correctly concluded, "Citrix did not improperly compare the prior art to the asserted claims of the '479 patent as a defense to literal infringement, but properly compared the accused product-GoToMyPC-to the asserted claims."
District Court Order
,
C. Citrix's Invalidity Defense
Citrix's infringement defense was firmly rooted in a limitation by limitation comparison between the asserted claims and the GoToMyPC product. But Citrix also presented an alternative invalidity defense that focused on its prior art BuddyHelp product. It argued that under the trial court's claim construction claims 24 and 45 were valid, but not infringed, J.A. 1489-90, 2509, but that if Communique attempted to expand the scope of its claims to include systems in which a location facility merely "directs" other components, such as the end point computers, to create the communication channel, J.A. 1901; see *742 also J.A. 1477-81, then the claims would be invalid in light of the prior art, J.A. 2509-15; see also J.A. 1518-19, 2462, 3501-02.
There was nothing improper about this argument. We have previously stated that "there is no 'practicing the prior art' defense to literal infringement."
Tate Access Floors, Inc. v. Interface Architectural Res., Inc.
,
In
Tate
, for example, we declined to overturn a preliminary injunction barring sales of allegedly infringing floor panels where a party's infringement defense rested on its claim that its floor panels could not "literally infringe because they merely practice the prior art, or that which would have been obvious in light of the prior art."
We confronted an analogous situation in
Zenith
.
Cases such as
Tate
and
Zenith
make clear that an accused infringer cannot defeat a claim of literal infringement or establish invalidity merely by pointing to similarities between an accused product and the prior art.
This is the problem Communique faced here. Citrix argued that GoToMyPC does not include a "location facility" that establishes a communication channel between a remote computer and a personal computer, but that if Communique relied upon an "overbroad application" of its claims to ensnare GoToMyPC, then the asserted claims would also cover BuddyHelp. J.A. 1355. This argument did not rest on an improper "practicing the prior art" defense, but instead correctly recognized that claim terms must be "construed the same way for both invalidity and infringement."
Amgen Inc. v. Hoechst Marion Roussel, Inc.
,
D. Prejudice
We also reject Communique's assertion that the comparisons Citrix made between GoToMyPC and BuddyHelp were "devastatingly prejudicial to the integrity of the trial." First, we have never suggested that any comparison between an accused product and the prior art mandates a new trial.

E. The Reexamination Record
We conclude, moreover, that the trial court did not abuse its discretion in ruling that while the PTO reexamination record could be used at trial, the jury could not be informed that Citrix was the party that requested the reexamination. J.A. 37;
see
Sprint/United Mgmt. Co. v. Mendelsohn
,
III. CONCLUSION
Accordingly, the order of the United States District Court for the Northern District of Ohio denying Communique's motion for a new trial is affirmed.
AFFIRMED
Because Citrix does not appeal the district court's determination that the '479 patent is directed to patent-eligible subject matter under
Before the case went to the jury, Communique moved for judgment as a matter of law ("JMOL") of no invalidity, J.A. 2666, but the trial court deferred ruling on this motion.
