SAN JOSE -- Tessera Technologies inc. today announced an initial determination by the U.S. International Trade Commission (ITC) has found that Sharp Corp.'s "face-up" chip-scale packages are violating Tessera's patents.
Sharp's chip-scale packaged devices are used in a range of system products, including mobile telephones, MP3 audio players and personal digital assistants (PDAs), according to San Jose-based Tessera.
The ITC's initial determination will be reviewed by the full commission and the U.S. President prior to implementation of any order banning the importation of products, said Tessera. The company filed its complaint before the ITC on March 28, 2000, and the trade commission initiated its investigation one month later.
Tessera has sued Sharp and Texas Instruments Inc. in federal court, accusing the two companies of infringement of the same two U.S. patents involved in the ITC probe. The suit against Dallas-based TI is now scheduled to go to trial on Nov. 26, according to Tessera.
