uPI Semiconductor Appeals $620,000 Fine Levied by ITC in Patent Enforcement Case

uPI Semiconductor appealed the results of a Section 337 patent enforcement case that resulted in a $620,000 fine for the company. The International Trade Commission imposed the fine in November, after finding violations of a consent order in the Section 337 patent investigation of certain DC-DC controllers and products containing same (337-TA-698). Complainant Richtek had alleged uPI continued to import and sell the products in the U.S., in violation of a 2010 agreement that ended the investigation.
