Jusung Sues AKT

Jusung Engineering Co. Ltd. filed a patent infringement lawsuit against US-based Applied Komatsu Technology, Inc. (AKT) and AKT’s affiliate A1 Engineering. Jusung is a TFT LCD and semiconductor process equipment manufacturer and competes with AKT in producing plasma enhanced chemical vapor deposition (PECVD) systems. The lawsuit was filed in Seoul District Court.

The patent involves the core technology for large-area PECVD and is related to the chamber structure applied in PECVD equipment for LCDs and solar cell equipment.

Earlier in February, AKT sent letters to Jusung’s customers in Taiwan that Jusung was infringing AKT’s patents and is against the Fair Trade Law. Jusung’s request for a lawsuit at the Taipei High Administrative Court was refused on the grounds that the Fair Trade Commission considered AKT’s actions as legal.
