CD software developer Roxio, a spin-off of Adaptec, has countersued Gracenote, owner of the CDDB service a month after Gracenote sued Roxio. Gracenote sued Roxio in May claiming that Roxio uses a CD information database in its new Easy CD Creator that violates Gracenote's patents.
Roxio didn't extend its contract with Gracenote to use Gracenote's CDDB database, but instead changed its CD products to use open-source service called FreeDB. Now Roxio sued Gracenote claiming that Gracenote fraudulently got their database patent and their CDDB trademark by failing to disclose key information to the U.S. Patent and Trademark Office.
