The U.S. Supreme Court left intact a ruling that lets Tessera Technologies Inc. (TSRA) seek damages from Qualcomm Inc. (QCOM) and four other companies for infringing patents covering computer-chip packaging.
The U.S. International Trade Commission said in 2009 that those companies, along with Motorola Inc. (MOT), 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.
The cases are Spansion v. International Trade Commission, 11-127, and Qualcomm v. International Trade Commission, 11-128.
