The companies Infernal Technologies and Terminal Reality filed a lawsuit this week against Microsoft pointing to the patent infringement of a graphics engine during the development of some of the games of the owner of the Xbox. The infringement, they argue, is that the company has misused lighting and shading technologies.
Terminal Reality was the studio responsible for Nocturne, BloodRayne and The Walking Dead: Survival Instinct – and their Infernal Engine was licensed so that several companies could use their patented development techniques.
In the case, the Microsoft games that infringed the patents 6,362,822 and 7,061,488 were: Halo 5, Sea of Thieves and several titles of the series Forza and Crackdown. The two companies argue that Microsoft is familiar with them because, in 2007, the company had a patent application rejected on account of the rights already granted to the two companies. This was only surpassed in 2009 when Microsoft worked with Terminal Reality to develop a Star Wars title and gained access to the source code.
As late as 2016, Electronic Arts confronted the two patents and claimed that the technology could not be registered. However, the request was denied and the company entered into an agreement with the two companies at the time.
