Seoul Semiconductor claims patent litigation win in Germany against Everlight

South Korean LED maker Seoul Semiconductor Co Ltd says that it has won a patent litigation lawsuit against Taiwan-based Everlight Electronics Co Ltd in Germany.

The patent involved relates to an LED package structure for thermal dissipation. Everlight purchased this patent from a US company in 2017, and subsequently brought a patent lawsuit against Seoul in the Manheim Court of Germany.

However, this December the Manheim Court ruled in favor of Seoul and ordered that Everlight, as the losing party, should bear the statutory costs of the court proceeding.

Seoul had already (earlier this year) won a patent litigation lawsuit against Everlight in the UK, when the UK Patent Court also ordered that Everlight must pay about $1m in litigation costs to Seoul. In the meantime, Seoul is pursuing patent infringement lawsuits against a global distributor of Everlight’s high-power and mid-power LED products in Germany, Italy and Japan.

Seoul Semiconductor notes that Everlight has previously sued another of its competitors in Japan after purchasing a patent from a foreign company, but it lost that action too. In April 2017, Everlight filed a patent lawsuit against Nichia Corp and Citizen Electronics in Japan, relying on the purchased patent. However, the Tokyo District Court dismissed Everlight’s lawsuit this October.

“Seoul has invested approximately 100 billion won per year in research and development to ensure that it creates its own cutting-edge technology and products, thereby establishing its own formidable patent portfolio,” says Nam Ki-bum, executive VP of the Lighting Department at Seoul.
