Kyocera obtains judgment of invalidity against patent asserted by Dutch telecommunications company Koninklijke KPN N.V.

Client(s) Kyocera International, Inc.

Jones Day successfully defended Kyocera Corporation and Kyocera International, Inc. against allegations that their mobile phones infringed a patent relating to error-checking telecommunications technology. Judge Stark of the District of Delaware granted Kyocera’s motion for judgment on the pleadings under 35 U.S.C. § 101, ruling that the claims of the asserted patent are directed to an abstract idea and do not constitute patentable subject matter. Jones Day also obtained dismissal of Kyocera International from the case for lack of venue in view of the Supreme Court’s TC Heartland decision.
