(CN) - Microchip Technology told the International Trade Commission that three competitors are importing chips that violate its patents for integrated circuit devices.
In its complaint to the ITC, Microchip claims that Intersil Corp. of Milpitas, Calif.; Ziker Labs of Austin, Texas; and Techwell of San Jose, violate six patents on the structure and manufacture of computer chips.
Microchip asked the ITC to issue a permanent exclusion order and a cease and desist order on 15 products.
Microchip, which has manufacturing plants in Tempe, Ariz. and Gresham, Ore. also sued the three rival manufacturers on the same issue in Phoenix Federal Court.
Patentholders often pursue simultaneous actions with the ITC and federal courts because the ITC process usually takes less than 15 months to complete and offers the immediate remedy of blocking importation of products found to infringe on a patent.
Findings of the ITC also can be introduced as evidence in federal proceedings, which can take years to reach a conclusion.
Microchip's complaint was filed with the ITC by Jo Dale Carothers, with Covington & Burling, of San Diego.
