SAN FRANCISCO—Tessera Technologies Inc. said Friday (May 27) that it filed a complaint through one of its subsidiaries against Sony Corp. in California state court.
The suit, filed in California State Court of Santa Clara County, alleges that Sony—a Tessera licensee—has not fully complied with its contractual obligation to pay royalties to Tessera (San Jose, Calif.).
"Under our Agreement with Sony, we have the right to examine and audit Sony’s records regarding amounts due, as we typically have with all our licensees," said Robert Young, Tessera's president and CEO, in a statement. "We are bringing this suit because Sony has not paid all of the royalties owed to us under the contract."
Tessera said Friday's suit is separate from a patent infringement suit it brought against Tesera and Renesas Electronics Corp. in October U.S. federal court in Delaware. Tessera is currently involved in at least four litigations against semiconductor vendors and other electronics firms.
