Sony Sued for Blu-Ray Patent Violation
Jaidan writes "According to a Gamespot article, a California-based company named Target Technology is suing Sony over patents it allegedly holds for silver based reflective surfaces. The suit claims that products marketed under the Blu-ray name infringe on a patent it owns for reflective layer materials in optical discs. 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. ' 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. Target does not specify in its suit whether it believes all of Sony's Blu-ray discs infringe on its patent, or the suit applies to just a portion of the discs manufactured. The patent was filed in April of 2004 and granted in March of 2006.'"
After doing a little looking at thier site, Target Technology gets their name because they do actually make products with this technology. The make silver alloy targets for sputtering the metal onto optical discs, and their targets are currently used manufacture of many DVD-R's and other optical discs. I would guess (though I don't have enough information to be sure) that they think Sony looked at the compostion of their targets, said "hey, these work really well," and decided to make their own targets of the same compesition for their Blu-ray discs. True or not, I have no idea, but it is at least possible a valid patent case. It's not like this is just an company who hoards patents and licenses them, they actually make products based off of those patents.
