Cloud gaming service Gaikai hasn't really made waves since it was bought by Sony in July. But now the company is facing a court battle with Delaware-based T5 Labs, which alleges that Gaikai infringed on its patent.
The complaint (via Gamasutra) claims that T5's patent for "Sharing a Graphical Processing Unit Between a Plurality of Programs" has been infringed upon by Gaikai's game streaming technology. The claim goes on to state that it sent Gaikai written notice of the infringement, and that the company continued to knowingly infringe afterwards. The company had previously considered legal action against OnLive for the same type of technology, but hasn't pursued a case.
