Report: Chinese Inventors Sue Motorola, Ericsson

Two Chinese inventors have sued subsidiaries of Motorola Inc. and Ericsson Mobile Communications AB, charging they violated a patent on a Chinese-character input method for mobile phones, according to a report on the Web site of the official China Daily newspaper.

The inventors, Hu Xuanhua and Hu Bin, said they had given Dalian Hanpu Application Technology Corp. the exclusive right to use the input method.

Motorola Electronics Co. Ltd. (China), Ericsson (China) Co. Ltd. and Beijing Ericsson Mobile Telecommunications Co. Ltd. used the technology in their products without authorization, the inventors allege, according to China Daily.

Motorola China allegedly used the patented input method in its CD928, M366C, V2088 and L2000 handsets, and Ericsson's China businesses used it in the T10S, T18SC and R320SC, the inventors said.

The inventors want Ericsson and Motorola to stop using the input method. They want the Motorola business to pay temporary compensation of 10 million renminbi (US$1.2 million) and Ericsson's subsidiaries to pay 5 million renminbi. They also sued Beijing Lufthansa Shopping Centre, a large, high-end mall in China's capital city, seeking to stop it selling products containing the technology.
