FINNISH PHONE MAKER Nokia has filed a second patent infringement lawsuit against rival HTC, claiming the firm is infringing a further nine of its patents.
Nokia has confirmed to The INQUIRER that it filed a second court case against HTC and its flagship HTC One smartphone in the US, adding nine more patents to the firms' ongoing dispute.
According to Nokia, these patents relate to; hardware features such as enhanced speech and data transmission, efficient component layout in compact unibody designs and worldwide roaming capability, application data sharing between phones, permissions management in applications, video encoding and decoding, and expanding a device's capabilities with new applications.
Speaking to The INQUIRER on Friday, a Nokia spokesperson said, "Nokia has filed further cases in the United States alleging that HTC products infringe additional Nokia patents.
"HTC has shown no intention to end its practices, instead it has tried to shift responsibility to its suppliers. We have therefore taken these further steps to hold HTC accountable for its actions.
"Nokia's new actions include a second complaint to the US International Trade Commission and a complaint to the US District Court for the Southern District of California in San Diego, US. These cases cover nine Nokia patents new to the dispute, bringing the total Nokia patents asserted against HTC in one or more of our actions around the world to 50."
This comes just weeks after Nokia went after ST Microelectronics (STM), the supplier of the microphone for the HTC One, claiming the firm infringes its technology patents. The court ruled that HTC can continue to use microphones that it already bought from STM, but will need to replace those in future products.
HTC told us that it would not comment yet. µ
