Sony faces Blu-ray lawsuit

Sony has found itself in legal hot water as a small technology company, Target, has alleged that the Blu-ray format infringes on patents that Target has held since 2006.

Three Sony divisions have been named in the suit, Sony Computer Entertainment America (SCEA), Sony Pictures and Sony DADC US.

California based Target claim that the silver-based alloy film found in the Blu-ray was invented by it, and was created to be used on optical discs.

In all, three suits have been filed, the other two going against Williams Advanced Materials and its customers for a patent on another optical disc alloy.

Sony hasn’t commented on the lawsuit yet, and may have little to say as Target is seeking a jury trial.
