Nokia Tells U.K. Court HTC Is Copying Handset Texting Technology

Nokia Oyj, the Finish company selling its handset business to Microsoft Corp, told a London court that Taiwanese phonemaker HTC Corp. was copying its technology designed to help transmit voice and text messages.

Nokia is suing HTC for infringement of the “024 patent,” which covers the technology, lawyers for the Espoo, Finland-based company said in documents filed at a London court for the trial beginning today. HTC is seeking to revoke the patent, Nokia said.

Nokia has filed 50 infringement claims against HTC in the U.S., U.K., Germany and Italy since May 2012, Mark Durrant, a company spokesman, said in an e-mail. It won a U.S. ruling Sept. 23 after a judge found HTC had violated two patents for a way to remove errors in radio signals and another for a process to deal with different radio frequencies.

The patent claim in today’s case relates to a group of four HTC handsets, including the Wildfire S and One SV, which contain certain chips manufactured by Qualcomm Inc. and Broadcom Corp., Nokia’s lawyers said in court filings.

Nokia was the world’s biggest maker of mobile phones before its 14-year streak came to an end in 2011 when Samsung Electronics Co. overtook it. Nokia has sought to use patent licensing to recoup some of the money it spent on phone innovations. Those patents will stay with Nokia after it sells its handset business and licenses its technology to Microsoft for $7.2 billion.

Joe Dawes, an external spokesman at London-based Nelson Bostock Group Ltd. representing HTC, declined to immediately comment on the trial.

HTC had a 2.8 percent share of the global smartphone market in the second quarter of 2013, compared to Nokia’s 3.1 percent, according to Bloomberg Industries data.

The case is HTC Corp. v Nokia Corp. in the U.K. High Court of Justice, Chancery Division, case no HC12F02047.
