Nokia files complaint with US trade commission

HELSINKI (FINLAND): Nokia Corporation, the world's largest mobile phonemaker, on Friday said it has filed a complaint with the United States International Trade Commission alleging that chipset maker Qualcomm has engaged in unfair trade practices by infringing on its patents.

The Finnish company has asked the ITC to start an investigation and issue an order to bar imports to the United States of chipsets and products that allegedly infringe on its patents, Nokia said.

"Qualcomm's unfair trade practices include importing product, selling products for importation, and/or selling products after importation, and inducing others to import products such as handsets, that infringe Nokia patented technology in certain Qualcomm GSM/WCDMA and CMDA2000 chipsets," Nokia said.

Nokia's complaint is the latest in a multinational legal battle with Qualcomm Inc, the world' No 2 chipmaker for mobile phones which licenses its technology patents. In June, Nokia filed a lawsuit in a Texas district court claiming unauthorised use of its Brew and MediaFlo patents, which allow fast, high-quality transfers of audio and video multimedia to wireless subscribers.

In April, Qualcomm filed a patent infringement lawsuit in Texas against Nokia, allegedly involving certain types of mobile software download and execution environments.

Shares in Nokia rose 1 per cent to USD 28.7 in Helsinki.
