Delaware-based game streaming patent holder T5 Labs has filed a complaint against Gaikai, alleging that the latter has knowingly infringed on its streaming patent.
T5 says that it owns a patent called "Sharing a Graphical Processing Unit Between a Plurality of Programs", which allegedly describes a system similar to that which the Sony-owned Gaikai
uses to stream video games.
The company claims that Gaikai infringes on this patent "by making, using, offering for sale, selling and/or practicing the inventions" covered by the patent, "at least by providing a system and methods of sharing a graphics processing unit between a plurality of programs."
T5 alleges that it gave Gaikai written notice of the infringement, and that Gaikai then knowingly continued to infringe on the patent.
"T5 has suffered and will continue to suffer damages in an amount to be proved at trial," reads the complaint
. The company is looking to receive interest, costs and disbursements. Gamasutra has contacted Gaikai for a response.
This isn't the first time that T5 has tussled with the competition -- at the start of 2011, it said that it was considering legal action against OnLive, as it believed it was entitled to the patent rights on video gaming inventions covered by OnLive.
