SAN JOSE, Calif.--(BUSINESS WIRE)--May 15, 2008--Tessera Technologies, Inc. (Nasdaq:TSRA), a leading provider of miniaturization technologies for the electronics industry, today provided a status update regarding its DRAM International Trade Commission (ITC) action.

Tessera has filed a motion to withdraw one of the four patents asserted in its case against a number of DRAM manufacturers before the ITC. The company is proceeding in the action with the three remaining patents, two of which have been successfully asserted in a number of prior actions and found to be valid and enforceable by those courts.

"We do not believe the withdrawal of this patent will affect the scope of our case," said Scot Griffin, senior vice president and general counsel, Tessera. "Two of the remaining patents have been litigated in prior legal actions that were resolved in Tessera's favor, and we remain confident in the strength of our IP."

The hearing in the DRAM ITC Action is scheduled to begin on September 22, 2008.
