Erise IP recently achieved a key Patent Trial and Appeal Board (PTAB) win on behalf of video game developer Ubisoft Entertainment SA.

Highlighted in the Law360 article “PTAB Nixes Claims On Virtual Reality Patent,” PTAB issued an Oct. 16 decision that found Ubisoft “showed that certain claims of Princeton Digital Image Corp.’s patent covering systems and methods for controlling a ‘virtual reality’ computer system are unpatentable.”

The decision settled a patent infringement suit Princeton filed against Ubisoft in Delaware federal court in February 2013. Specifically, Princeton had alleged that Ubisoff infringed the “129 patent” with various virtual reality games, with titles such as “Just Dance” and “Just Dance Summer Party,” according to Law360.

The PTAB decision in favor of Ubisoft followed Ubisoft’s request that the board review claims of Princeton’s patent.

PTAB’s written decision stated that Ubisoft showed by “a preponderance of evidence” that numerous claims of the Princeton patent were unpatentable.

Erise IP attorneys Eric A. Buresh and Mark C. Lang represented Ubisoft in the case.
