SAN DIEGO -- Qualcomm Inc. today (July 25) announced it has filed a suit against Texas Instruments Inc. for breach of contract over code-division multiple access (CDMA) technology.
The suit, filed in a U.S. court in Delaware, involves a breach of contract regarding a "patent portfolio agreement" that was signed in December 2000 ( see Dec. 4, 2000 story ). The agreement covers both companies' patent portfolios, providing rights to each company to supply integrated circuits on a worldwide basis for all wireless standards.
The complaint seeks damages and termination of TI's rights under the agreement.
In May, TI said it was preparing for a charge, and analysts believe the chip giant may have a shot when it enters the market with a commercial cdma2000 chip set. The move was a direct threat to Qualcomm, which dominates the CDMA chip market (see May 13 story ).
At about the same time, TI announced a partnership with STMicroelectronics to develop and market a jointly defined CDMA chip set. Finnish cell phone giant Nokia will play a role in the partnership, providing much of the protocol software stack (see May 15 story ).
