Treehouse Avatar LLC v. Valve Corp., No. 22-1171 (Fed. Cir. 2022)
Annotate this Case
Treehouse sued Valve for infringement of its patent, which discloses a method of collecting data from an information network in response to user choices of a plurality of users navigating character-enabled network sites on the network. Valve owns two accused video games that involve team-based competitions. The parties adopted the interpretation of the “CE limitation” that the Patent Trial and Appeal Board reached in a previous inter partes review: “A network location, other than a user device, operating under control of a site program to present a character, object, or scene to a user interface.” Treehouse’s infringement expert, Friedman, submitted a report that applied the plain and ordinary meaning for the CE limitation rather than the agreed-upon construction,
The district court ruled in favor of Valve, striking every paragraph of Friedman’s report that Valve requested and finding noninfringement because Treehouse failed to offer admissible evidence showing that Valve’s video games operated the CE limitation. The Federal Circuit affirmed. The district court did not abuse its discretion in striking expert testimony that did not rely upon the parties’ own agreed-upon construction, that the court adopted, nor err in finding that Treehouse failed to rebut Valve’s evidence of noninfringement.
The court issued a subsequent related opinion or order on December 1, 2022.
