Amkor Technology Inc. (Chandler, AZ) reported that in regard to its patent infringement suit filed against Carsem in the International Trade Commission, the judge has determined initially that Carsem did infringe some of Amkor’s patent claims, that some of the 21 asserted patent claims are valid, and all of Amkor’s asserted patent claims are enforceable.
At the same time, the judge did not find a statutory violation of the Tariff Act – a decision Amkor says is disappointing. "We are disappointed that the initial determination did not find a statutory violation of the Tariff Act, which would have allowed us to seek an order excluding Carsem from importing their Micro Leadframe Package product into the US," stated Amkor President and COO John Boruch. "Nonetheless, Amkor has many patents that protect our investment in Micro LeadFrame package technology, and we will continue to protect our intellectual property rights related to QFN products, including Carsem’s Micro Leadframe Package."
The suit relates to Amkor’s Micro LeadFrame package technology, a proprietary version of a quad, flat-pack, no lead IC package, also called QFN. Amkor said it would file a petition to have the judge’s ruling reviewed by the full International Trade Commission.
