A Western District of Texas jury delivered a substantial blow to Cisco Systems, rendering a $65.7 million verdict on Thursday for directly infringing Paltalk's patent related to hybrid audio servers. The jury found that Cisco not only infringed but also failed to demonstrate the invalidity of specific patent claims.

Cisco $65.7M Verdict : Trial Overview and Verdict

The high-stakes trial spanned nearly a week, commencing on Monday and culminating the day after Cisco's unsuccessful attempt to secure a mistrial. U.S. District Judge Alan Albright denied Cisco's motion, which sought to declare a mistrial based on alleged changes in judicial guidance concerning the interpretation of the claim term "each." The jury concluded that "each" should be understood in its plain and ordinary meaning, encompassing "one or more."

Paltalk's legal team, represented by Susman Godfrey attorneys Max Tribble and Kalpana Srinivasan, expressed elation on Friday. "We are thrilled to have achieved this result for Paltalk, our client of nearly 20 years," they stated. Cisco's counsel has yet to respond to the verdict.

Legal Proceedings and Arguments

Paltalk Holdings Inc., known for its video chat platforms Paltalk and Camfrog, initiated the lawsuit in late July 2021, accusing Cisco of infringing on its patent titled "Hybrid server architecture for mixing and non-mixing client conferencing." The infringement allegation specifically targeted Cisco's Webex products.

Throughout the trial, Cisco contested the validity of the patent, including a September 2022 motion for an ex parte reexamination. However, the examiner ultimately dismissed Cisco's invalidity claims. On the day of the verdict, Cisco filed a motion for judgment as a matter of law, arguing that Paltalk had selectively asserted method claims over system claims and that selling software capable of practicing a patented method does not constitute direct infringement.

Additionally, Cisco contended that Paltalk failed to provide evidence demonstrating that Webex determines which clients cannot mix multiple audio streams as specified in Claim 1 of the patent. The company also criticized Paltalk's damages analysis, asserting that using the entire market value of Webex and Webex Audio was unjustified.

Cisco $65.7M Verdict : Jury's Decision and Implications

The jury's unanimous decision affirmed that Paltalk successfully proved Cisco directly infringed claims one through five of the patent. Moreover, Cisco did not establish that the claims were invalid due to obviousness or an inadequate written description, as per the verdict form.
