ITC delays Actions Semi-SigmaTel patent case decision

The U.S. International Trade Commission (ITC) extended the target date for the completion of the investigation of a patent infringement claim brought by SigmaTel Inc. against Chinese fabless IC provider Actions Semiconductor Co. Ltd involving audio processing ICs, according to an ITC notice issued on June 20.

The commission remanded a portion of the investigation to ITC administrative law judge Paul Luckern for further consideration, according to the notice. The commission also reversed Luckern's construction of one of the claims in one of the patents involved in the case.

Luckern ruled in March that Actions Semi infringed two SigmaTel patents. Actions Semi has previously denied infringing SigmaTel patents, arguing that they are invalid.

SigmaTel emphasized that the ITC remanded only one portion of the investigation back to Luckern and interpreted the ITC notice as confirmation of Luckern's ruling that Actions Semi infringes two patents.

"SigmaTel is pleased that the ITC largely confirmed Judge Luckern's infringement findings," said Ron Edgerton, SigmaTel CEO, through a statement.

In a statement, Actions Semi said the products under review by the ITC constitute a non-material portion of Actions' overall revenue mix. The company added it estimates less than 10 percent of its products sold in the global market are shipped to the U.S., and that it has introduced newly designed products for the U.S. market.
