Palm on Tuesday called the lawsuit filed against it by NTP unwarranted, saying the patents cited are of “doubtful validity,” Reuters reports.NTP, a privately held patent holding company, announced Monday that it was charging handset maker Palm in a lawsuit with patent infringement, accusing the company of offering or employing “products, services, systems and processes” that infringe on NTP’s patents.But Palm countered by saying that the seven patents NTP claims were infringed upon have thus far been rejected as invalid by the U.S. Patent and Trademark Office, according to Reuters.In a statement released to Reuters, the defendant in the case said: “Palm is disappointed that, after many months of silence and repeated rejections of NTP’s claims by the PTO, NTP has chosen to sue on patents of doubtful validity.” NTP made headlines recently with its battle against Research in Motion, maker of the uber-popular BlackBerry—a saga that ended in March with RIM paying $612.5 million to NTP to settle the patent infringement fight.— Compiled by Dave Gradijan Related Links: NTP Hits Palm With Patent Infringement Suit BlackBerry on the Edge: RIM-NTP Patent CaseCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
