MANHASSET, N.Y. China-based fabless IC company Actions Semiconductor Co. said Friday (Aug. 4) that the U.S. International Trade Commission has issued a determination in favoring Actions in the patent infringement lawsuit between the company and Austin-based semiconductor supplier SigmaTel Inc.
On June 20, the ITC modified a key claim construction under patent 522 and requested that administrative law judge reconsider the infringement issue in light of the modified claim construction.
After reconsidering the infringement issue, the judge determined that Actions' products utilizing current firmware 952436 do not infringe the disputed patent. Actions has previously denied infringing Sigma-Tel patents.
The final determination is expected to be issued Sept. 15.
SigmaTel issued an announcement of its own Friday, saying the ITC judge's recent ruling does not affect the full ITC's previous ruling that all of the accused Actions products and firmware versions infringe SigmaTel's 6,633,187 patent. The decision also does not affect the ITC's ruling that other versions of Actions firmware infringe the 6,366,522 patent, according to SigmaTel.
"Even after today's ruling, the ITC still believes all of the Actions products and firmware versions we previously accused of infringement still infringe one or more SigmaTel patents. Based on these previous infringement findings, the ITC still has a very firm basis from which to issue an exclusion order in September," said Ron Edgerton, SigmaTel's chairman and CEO.
Actions is on schedule to commence mass shipments of its recently announced 7500 series products that utilize 0.18 micron process technology in the next few weeks, and plans to introduce its 13 series by the end of 2006.
