Blu-Ray embroiled in patent row

According to Gamespot, Target Technology, which designs and supplies corrosion resistant thin film alloys for optical disc applications, wants damages for alleged patent violations relating to the Blu-ray technology.

In the dock will be Sony Computer Entertainment America, Sony Pictures, and Sony DADC. The technology in question is the reflective layer materials in optical discs.

Target's patent relates to the use of cheaper silver-based alloys with the advantages of gold. The patent was filed in April of 2004 and granted in March of 2006.

Target wants a permanent injunction preventing Sony from violating its patent rights in the future. If it gets it then Blu-ray disks could be off the shelves, although this is fairly unlikely. Target wants damages with interest, multiplied due to what it characterizes as deliberate and willful infringement.

Sony has not commented on the case yet. µ
