Sony get sued AGAIN… this time over Blu-Ray

Echoing the Immersion Tech lawsuit against them for unlawfully including rumble in its control pads, it seems that someone else is on their backs now.

For what may you ask?

While the former two companies have since patched things up, Sony opted to leave rumble by the wayside when it was designing the PlayStation 3’s motion-sensing Sixaxis controller, initially. The electronics giant couldn’t avoid patent headaches entirely, however, as Irvine, California-based Target Technology Company filed suit earlier this month, seeking damages for alleged patent violations relating to the Blu-ray technology used in the system.

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.

Neither Sony representatives nor Target attorneys had returned GameSpot’s requests for comment as of press time.
