Seoul Semiconductor wins all five patent litigations against Everlight

South Korean LED maker Seoul Semiconductor Co Ltd has won a patent invalidity litigation that was filed against Everlight Electronics in the Korean Patent Court.

Everlight’s patent was purchased from a US company in 2017. Previously, Seoul also filed patent invalidation litigation against this patent’s Europe (UK) counterpart in the UK Patent Court. Following the UK challenge, Everlight voluntarily acknowledged that its patent is invalid, and the UK Patent Court ordered Everlight to pay about $1m in litigation costs to Seoul.

Despite the UK Court’s declaration of invalidation, the Korean Patent Trial Board dismissed Seoul’s invalidation challenge against Everlight’s patent. However, the Korean Patent Court has now reversed this first-instance decision and declared the challenged claims of Everlight’s patent to be invalid (consistent with the outcomes of the UK patent litigation). As a result, Seoul says that it has won all five patent litigations filed against Everlight.

In particular, a few weeks ago the German court rendered a judgment in favor of Seoul’s patent infringement claims, including ordering a permanent injunction against sales of the accused Everlight products. The court also ordered a recall of all accused Everlight products sold after 13 July 2012 from the distributor’s commercial customers.

“To ensure that the efforts and value of technology innovators are respected, we have visited numerous companies around the world to explain our technologies while concurrently monitoring suspected infringing products,” says vice president Sam Ryu.
