Sony Sued Over Its Blu-Ray Discs

28 May, 2007, 12:13 pm IST | Priyanka Pradhan |

Sony Computer Entertainment America, Sony Pictures and Sony DADC, have been slapped with a patent lawsuit over its Blu-ray technology that uses metallic layers to reflect laser light in Blu-ray discs.

A UK based company, Target Technology, claims that Sony's Blu-ray discs infringe a patent it filed last year, for the use of certain metal alloys in the reflective or semi-reflective layers of an optical disc.

Although Target does not specify in its suit whether it believes all of Sony's Blu-ray discs infringe on the Target patent or whether the suit applies to just a portion of the discs manufactured, the company is seeking a permanent injunction that will prevent Sony from violating Target patent rights in the future, as well as damages, with interest.

It's quite short and it doesn't have any sort of versus multiplayer but The Darkness II is a polished and brutal shooter you should definitely check out, especially if you like ripping dudes to shreds.
