IPCom GmbH & Co., an intellectual property holding company, gave up three U.K. mobile-phone patents that are subject to a legal dispute with Nokia Oyj.
IPCom won’t defend three of the four patents at issue in a case filed at the High Court in London, Nokia spokesman Mark Durrant said in an e-mail today. IPCom continues to defend a network-related patent in the suit, he said.
The two companies are involved in patent litigation around Europe as IPCom seeks royalties for a portfolio of mobile-technology patents it acquired from Robert Bosch GmbH in 2007. IPCom has given up several patents in the U.K. to concentrate on the most important ones, Alistair Hammond, a spokesman for Pullach, Germany-based IPCom, said in an interview.
“All together, IPCom is defending four core patents attacked by Nokia in a number of different lawsuits with the aim of focusing efforts on its key patents,” he said. “As part of this strategy it has decided to let a number of lesser patents lapse in the U.K.”
IPCom indicated it would drop the patents in court papers filed this week, Hammond said. The step only concerns litigation in the U.K. and has no effect on cases in other countries, he said.
Both companies declared victory in a separate German case after a patent court in Munich yesterday struck down part of an IPCom patent. IPCom won’t appeal that ruling, because the company is “totally happy with the scope the patent now has,” Hammond said today.
Nokia is confident that its products don’t infringe the German patent in its amended form and the matter of infringement will need to be investigated from scratch, Durrant said.
