Tessera Lodges New Suit Against Sony Over Royalties

Chip-packaging developer Tessera Technologies Inc. (TSRA) has sued Sony Corp. (SNE, 6758.TO), alleging the Japanese conglomerate failed to pay promised royalties.
"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," Tessera President and Chief Executive Robert A. Young said. "We are bringing this suit because Sony has not paid all of the royalties owed to us under the contract."
The breach-of-contract suit adds to a separate patent infringement suit Tessera, whose primary business is licensing its technology, lodged against Sony and Renesas Electronics Corp. (RNECY, 6723.TO) last October.
Tessera also earlier this year said it would end its license agreement with Amkor Technology Inc. (AMKR), a provider of semiconductor assembly and testing equipment, over multiple issues including alleged license agreement breaches.
Meanwhile, an appeals court earlier this week affirmed an International Trade Commission ruling saying Elpida Memory Inc. (6665.TO), Smart Modular Technologies Inc. (SMOD) and several other technology companies didn't infringe on Tessera's patents for chip packaging.
The technology at issue enables a semiconductor manufacturer to protect chips from mechanical and thermal damage without contaminating the endpoints, or electrical terminals, that connect the package to another device such as a printed circuit board. Tessera shares closed at $17.40 Thursday and were inactive premarket. The stock is off 21% year-to-date. -By Drew FitzGerald, Dow Jones Newswires; 212-416-2909; Andrew.FitzGerald@dowjones.com (END) Dow Jones Newswires May 27, 2011 07:52 ET (11:52 GMT)
