Nokia Oyj sued rival mobile phone maker HTC Corp (宏達電) for selling products in the US, including the HTC One handset, that allegedly infringe three of its patents.
The three patents pertain to “terminal, method and computer program product for interacting with a signaling tag,” according to the complaint Nokia filed on Thursday in federal court in San Diego.
The Espoo, Finland-based company seeks a court order halting the alleged infringement and unspecified damages.
Nokia, which lost its 14-year title as world’s biggest seller of mobile phones to Samsung Electronics Co in 2011, is trying to expand revenue from its patent portfolio.
The company last year sued HTC in the US and in Germany over alleged patent infringements.
“Upon receiving the official document, HTC is to consider all legal options to protect our rights,” the Taiwanese company said in an e-mailed statement yesterday.
Shares of HTC fell 1.24 percent to close at NT$279 yesterday.
Separately, HTC became the best-selling mobile phone brand in Taiwan last month, accounting for a 30.6 percent market share, thanks to continued brisk sales of its popular 5-inch Butterfly phone and smoother production of its flagship HTC One, an HTC official said yesterday.
Samsung was in second place with a market share of 26.7 percent last month, the official said, citing figures from an authoritative market research firm.
Samsung’s new flagship model the Galaxy S4 did not hit local store shelves until late last month, which might have been a major factor behind the company’s drop to second place, market analysts said.
Sony Corp of Japan was third, securing an 18.4 percent share of overall handset sales in Taiwan last month, while the US-based Apple Inc was fourth with a 10.1 percent share.
Another Taiwanese manufacturer, Asustek Computer Inc (華碩), ranked fifth, with a 2.1 percent share.
