Cloud-Gaming Patent Holder Sues Sony Again for PS4 Infringement

August 4, 2020 by Paul Gluckman|Intellectual Property

The “remote play” and “share play” cloud-gaming features that Sony Interactive Entertainment (SIE) builds into the PlayStation 4 infringe a June 9 patent (10,681,109) for a display system with a visual server to generate and transmit images to a client, alleged an Intellectual Pixels Limited (IPL) complaint (in Pacer) Friday in U.S. District Court in Santa Ana, California: The three 3DLabs engineers who invented the technology are co-owners of IPL, which holds the patent. “SIE has been seeking to capitalize on the revolutionary technology that IPL and the inventors developed,” it said. “It has already announced its intention to release a new PS5 console that will also utilize IPL’s technology.” IPL's new action came nearly a year to the day after it sued SIE in the same court alleging infringement of four older cloud-gaming patents (see 1907260051). SIE countersued IPL Jan. 21 for a declaratory judgment of noninfringement. The case remains active, but COVID-19 delayed its discovery phase when California went into lockdown in mid-March. SIE didn’t comment Monday.
