CHANDLER, AZ – Isola USA Corp. filed a complaint with the US International Trade Commission claiming certain imports of prepregs, laminates and PCBs infringe claims of its patents.
 
In the complaint, the Chandler-based company alleged several Asia companies, among them Ventec Electronics, Taiwan Union Technology, ITEQ Corp., and Guangdong Shengyi Sci. Tech Co., of violating Section 337 of the Tariff Act of 1930.
 
The company is asking the US ITC to ban the imports of any materials or products that allegedly infringe Isola's patents, including Ventec's VT-47 and VT-48, TUC's TU-662 and TU-752, ITEQ's IT-200DK, and Guangdong Shengyi's S1000.
 
Last week, Isola asked the China courts for help in protecting its IP, naming TUC and ITEQ for patent infringements. TUC strongly denied the allegations, insisting Isola “stop harassing TUC customers and interested companies at once.” ITEQ did not publicly respond.
