Nov. 28 (Bloomberg) -- The U.S. Supreme Court left intact a ruling that lets Tessera Technologies Inc. seek damages from Qualcomm Inc. and four other companies for infringing patents covering computer-chip packaging.
The justices today turned away appeals in the case from Qualcomm, Spansion Inc., STMicroelectronics NV and units of Freescale Semiconductor Holdings and Advanced Micro Devices Inc.
The U.S. International Trade Commission said in 2009 that those companies, along with Motorola Inc., infringed patents owned by Tessera. A federal appeals court upheld that finding last year. Motorola split into two companies earlier this year, Motorola Mobility Holdings Inc. and Motorola Solutions Inc.
Motorola dropped out of the legal fight by licensing the Tessera patents in 2009. The patents are now expired, leaving the companies still in the case to fight over damages for past infringement.
Tessera, which is based in San Jose, California, rose after the Supreme Court acted, climbing 90 cents, or 5.8 percent, to $16.49 at 11:29 a.m. on the Nasdaq Stock Market.
The cases are Spansion v. International Trade Commission, 11-127, and Qualcomm v. International Trade Commission, 11-128.
