Terminal Reality Inc. and Infernal Technology, LLC, as patent owner and exclusive licensee, respectively, have filed suit against Activision Blizzard (3:18-cv-01397), asserting two patents generally related to lighting and shadowing in computer graphics. The plaintiffs accuse Activision Blizzard of infringement through the use and provision of certain game engines “that are capable of performing deferred rendering, deferred shading, deferred lighting, physically based shading, and/or physically based rendering”, as well as through the provision of video games allegedly developed using those engines, including Blur, Call of Duty: Infinite Warfare, Destiny, and Skylanders: SWAP Force, among others.
Infernal Technology, LLC, as exclusive licensee, and Terminal Reality Inc., as patent owner, have sued Microsoft (2:18-cv-00144) over the same two patents at issue in the case that the two Texas plaintiffs brought against Electronic Arts (EA) in September 2015. The asserted patents generally relate to lighting and shadowing in computer graphics, with the plaintiffs accusing Microsoft of infringement through the provision of Xbox consoles and Surface computers, along with a variety of games and game engines used to develop them. EA filed a motion to change venue (on which the district court never ruled), objections to an order construing disputed claim terms (which the district court overruled), and multiple petitions for inter partes review (IPR) (which resulted in final written decisions that did not cancel any of the challenged claims), all before the case against it was dismissed with prejudice, in light of apparent settlement, in January 2018.
