Wireless technology company Qualcomm said it <A HREF="http://news.yahoo.com/s/nm/20051107/tc_nm/qualcomm_nokia_dc">filed a patent infringement lawsuit</A> against Nokia, less than two weeks after Nokia and five other companies complained about Qualcomm's competitive practices to the European Commission. Qualcomm said it wanted Finland's Nokia, the world's No. 1 mobile phone maker, to stop selling certain mobile phone products in the United States, and demanded unspecified monetary damages from Nokia. The latest suit appeared to be a retaliation by Qualcomm for complaints to the European Commission, made on October 28 by Ericsson, Texas Instruments Inc., Broadcom Corp. and others. It could be the start of a a flurry of additional lawsuits from Qualcomm, analysts said.
