The suit, which names Sony Computer Entertainment America, Sony Pictures, and Sony DADC, claims that products marketed under the Blu-ray name infringe on a patent it owns for reflective layer materials in optical discs. The patent addresses what Target called a need for specific types of silver-based alloys with the advantages (but not the price) of gold. According to the patent, the alloys are also more resistant to corrosion than pure silver. The patent was filed in April of 2004 and granted in March of 2006.

Target is seeking a permanent injunction preventing Sony from violating its patent rights in the future, as well as damages with interest, multiplied due to what it characterizes as deliberate and willful infringement.

americans are really greedy, can' t believe how these people can do anything for the money, we never hear so many lawsuits except in the U.S, it became part of their culture.
