February 22, 2001–San Jose, California–The U.S. International Trade Commission (ITC) has scheduled an April 5 investigation into a patent infringement dispute filed by Tessera Inc. against Sharp Corp. and Sharp Electronics Corp last year. Tessera’s complaint alleges that Sharp semiconductor chips in certain chip-scale packages infringe Tessera patents, and seeks an exclusion order that would ban importation of Sharp’s packaging semiconductors and the OEM products that incorporate them.
Tessera also is currently taking legal action against Sharp and Texas Instruments for infringement of U.S. Patent Nos. 5,679,977 and 5,852,326 in the Northern District of California. The company claims that it resorted to administrative remedies in the ITC and litigation in federal district court after amicable business solutions could not be reached.
