MANHASSET, N.Y. High-voltage analog IC supplier Power Integrations has won a favorable decision in its patent-infringement case against Taiwan-based System General Corp. (SG), filed last year with the U.S. International Trade Commission (ITC).
The administrative law judge ruled that certain SG power-supply controllers infringe Power Integrations U.S. Patent Nos. 6,351,398 and 6,538,908, thereby violating section 337 of the Tariff Act of 1930. The judge upheld all of Power Integrations patent claims. It recommended the ITC issue an exclusion order against SG's infringing products, and against LCD monitors and AC printer adapters containing the infringing parts.
If the ITC adopts the judge's decision, SG must pay a tariff of 38 cents for each imported infringing chip and each imported product containing an infringing chip during the subsequent review period.
According to Power Integrations (San Jose), the infringing chips, which include the SG6840, SG6841, SG6841x3, SG6842, SG6842J and SG6843, comprise a significant percentage of SG's sales.
Power Integrations filed a patent infringement suit against System General in the U.S. Federal District Court in June 2004. The ITC began investigating the case in June 2005.
