The companies Terminal Reality and Infernal Technologies have accused Microsoft of violating in an “egregious and willful” manner some of their patents.
The Redmond giant, to be precise, is facing a lawsuit for the alleged violation of the Patent 6,362,822 and the Patent 7,061,488, related to graphics technologies for lighting and shadow management.
Terminal Reality claims to have implemented these technologies in the Infernal Engine graphics engine, the development of which has been carried out during the processing of games such as Nocturne, Bloodrayne, and The Walking Dead: Survival Instinct. The Infernal Engine was then licensed to other studios.
According to the documents of the case, Microsoft is accused of having violated these patents in the likes of Halo 5, the Crackdown series, in several members of the Forza series and in the recent PlayerUnknown’s Battlegrounds and Sea of Thieves.
According to the allegations, the situation was known for some time, but Microsoft intentionally avoided to investigate the issue in order to exploit the two patents despite the request for clarification.
The two companies state that the Redmond house had been aware of this since 2005. In 2007, it also made a request for a patent of this type, which was however rejected in the light of the existence of the two above. The lawsuit is underway and it will be up to the judge to decide which of the two parties is correct.
