Last week, Panasonic filed a patent infringement lawsuit against CMC Magnetics. According to an article at PC World, Panasonic claims that CMC infringed upon not one, but three of their patents.
The three patents named in the complaint are: U.S. patent 4,847,132, which covers a protective layer for a reversible data storage disc; patent 5,790,487, which relates to optical data recording media; and patent RE 37,185, which covers an optical recording head for use in an optical disc data storage system.
Panasonic asserts that CMC and two U.S. affiliates, Hotan and KHypermedia, infringed on all three patents. The company is asking the court for damages relating to the infringement and an injunction against further infringement.
