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.
