Mountain View, Calif.-based Orinda Intellectual Properties USA has filed suit against Sony, claiming the PS3-maker has infringed on Blu-ray-related patents.
In an August 20 court filing obtained by Edge, Orinda alleged that Sony infringed on patent number 5,438,560, which in broad terms describes methods for recording and reproducing information via optical disc.
Orinda also named as defendants subsidiaries Sony Electronics, Sony Computer Entertainment and Sony Computer Entertainment America.
Orinda has demanded a jury trial, and is seeking an injunction on manufacturing, sales and distribution of Blu-ray devices such as the PS3, computer peripheral products and dedicated Blu-ray players.
The plaintiff is also asking for "a reasonable royalty."
"Orinda has been and will continue to be damaged as a result of Defendants’ infringing conduct," the company said in the filing. "Defendants’ infringing conduct will continue unless permanently enjoined by this court."
This isn’t the first time that a company has sued Sony over Blu-ray. Target Technology sued Sony in May 2007 for alleged Blu-ray-related infringements. The case was dismissed a few months later.
