- Firm lost second in series of trials over wireless technology
- Shares fall as much as 12 percent after U.S. markets open
Unwired Planet Inc. lost the second in a series of London patent trials against Samsung Electronics Co. and Huawei Technologies Co. over technology that allows mobile phones to connect to the Internet.
Judge Colin Birss said the two patents in the case were invalid because of “obviousness” and should be revoked. The company’s shares fell as much as 12 percent after markets opened in New York.
Unwired Planet is suing some of the world’s biggest phone makers in London because it says their products rely on its proprietary technology. The Los Altos, California-based firm acquired a portfolio of more than 2,000 patents from Ericsson AB in 2013. Its shares rose as much as 20 percent after winning the first of six London patent trials in November.
“This setback has not diminished our faith in the European courts, which we believe continue to serve as a model to the rest of the world on how to conduct complex patent trials,” said Boris Teksler, chief executive officer of Unwired Planet.
Unwired Planet shares dropped to as low as $9.49, the biggest drop in more than a year.
The disputed patents are EP 2 119 287 (287) and EP 2 485 514 (514).
