SAN JOSE – A court hearing on alleged infringement of Tessera Technologies’ patents is now scheduled in late February.
 
The court date is the latest move in the U.S. International Trade Commission’s investigation regarding possible infringement of Tessera’s patents by Qualcomm, Freescale, Motorola, ATI Technologies, ULC, Spansion and ST Microelectronics.

On Sept. 7, Tessera filed with the ITC for permission to use certain confidential information to initiate a parallel action against several assembly service providers, including ASE, ChipMOS Technologies, Siliconware Precision Industries and STATS ChipPAC.

On Sept. 12, the providers filed a motion requesting the court stop Tessera from moving forward on the basis of the forum selection clauses in their respective Tessera license agreements.

Tessera’s ongoing arbitration with Amkor Technology regarding a failure to pay royalties due under its license agreement is proceeding toward a March 31 hearing. Tessera seeks a substantial monetary recovery from Amkor. Amkor has submitted an expert report contending that Tessera’s patents are invalid.

Tessera seeks remedies for infringement of its technology in two pending district court patent infringement actions, one in the Northern District of California and one in the Eastern District of Texas. Tessera’s right to recover damages against the California action defendants is expected to continue during the pending ITC action.

After a hearing on Nov. 1, the court issued an order permitting Tessera to file a complaint against the ASP defendants in the ITC or elsewhere.

In the Eastern District of Texas, the parties have stipulated the litigation will be temporarily stayed.
