Recently, Japanese LED product supplier Toyoda Gosei Co. Ltd. has filed a lawsuit with the Taoyuan District Court in northern Taiwan, accusing its Taiwanese counterpart Formosa Epitaxy Inc. of infringing on two patents asserted by the Japanese firm related to GaN-based LED chip production.

According to Hsu Hung-sheng, a lawyer for the Japanese firm, said his client has sought damages from Formosa Epitaxy and requested the court issue an injunction to bar the Taiwanese defendant from manufacturing and selling the disputed LED products.

Additionally, not long ago, Toyoda Gosei filed another lawsuit with the United States District Court for the Northern District of California Feb. 21, alleging that Formosa Epitaxy infringed on eight LED chip patents asserted by the Japanese firm.

For Formosa Epitaxy , the company announced that it has not received any notices from the courts in Taoyuan and California, it was unable to evaluate the impact on its operations from the litigation.

However, Formosa Epitaxy said it remains confident of its technology and will use the litigation as an opportunity to make a formal contact with Toyoda Gosei to safeguard its own rights.
