Terminal Reality developed a number of video games, such as Nocturne, Bloodrayne, Ghostbusters: The Video Game, Kinect Star Wars, The Walking Dead: Survival Instinct, and many others. Terminal Reality also developed a video game graphics engine, called the “Infernal Engine,” used in many of Terminal Reality’s games. In addition to using the “Infernal Engine” in its own games, Terminal Reality successfully licensed the “Infernal Engine” to other. On June 3, 2014, Terminal Reality granted Infernal Technology an exclusive license to a number of patents, including the Asserted Patents as defined below, and the exclusive right to enforce same.

According to the filing, Microsoft has released several titles such as Halo 5, the Crackdown series, multiple Forza titles, PlayerUnknown’s Battlegrounds, and Sea of Thieves which infringe Patents 6,362,822 and 7,061,488. Terminal Reality and Infernal Technologies say that Microsoft was familiar with the nature of the Patents since at least 2005. Additionally, a patent filing by Microsoft, based on the disclosure of Patent ‘488 and ‘822, was put forward but was eventually rejected.
