Orinda claims that patent 5,438,560 has been infringed, covers recording and reproducing optical discs such as CDs, DVDs, and Blu-ray Discs. The company has filed for an injunction stopping the production and sale of all Blu-ray players including PlayStation 3 systems. Orinda is also asking for "a reasonable royalty" from those Blu-ray players it wants to remove from sale.
Major console manufacturers are sued by supposed patent holders with some frequency, and Sony is no exception. In 2007, for example, Sony settled with force-feedback maker Immersion but had a lawsuit over the Blu-ray Disc format dismissed.
