According to court documents released today, Target Technology is suing Sony for patent infringements involving Blu ray disc technology.
Target says that Blu-ray infringes on patents held on the reflective-layer materials of the optical discs. The patent was filed in April 2004 and granted in March 2006.
Accroding to Target, the materials help discs corrode less easily than standard definition discs by using silver-based alloys instead of much more expensive and ineffective gold-based ones.
The company is seeking a permanent injunction and "significant" monetary damages.
Target also filed a seperate suit against the disc manufacturer Williams Advanced Materials, whom they accuse of violating another set of alloy patents held by the company. The company also claims that Target founder Han Nee was the original developer of the silver-based alloy materials used in current optical discs.
