Hanmi Semiconductor has effectively lost in a patent lawsuit it filed against rival Genesem over patents related to packaging equipment.

In fact, it lost more than it bargained for as the court nullified its patents.

Hanmi Semiconductor filed the suit against Genesem to the Seoul Central District Court in January 2021, claiming that the latter infringed on its patent related to a semiconductor package handling device (patent number 838365).

Hanmi Semiconductor has requested that the alleged infringement be stopped and damages of a billion won.

In response, Genesem asked the Intellectual Property Trial and Appeal Board to invalidate the patent, which it succeeded in.

The board said there were already preexisting patents to 838365 that were similar and said the patent wasn’t innovative.

Hanmi Semiconductor appealed against the decision but the Patent Court of Korea, the appeals court, dismissed the case.

Hanmi Semiconductor doesn’t plant to further appeal the case to the Supreme Court, sources said.

The original patent lawsuit filed by the company is likely to be dismissed as well as the patent in question has been nullified. The final judgment is expected next month at the earliest.

The Seoul Central District Court advised Hanmi Semiconductor to drop the suit and each party to pay for their legal fees.

Genesem, through its lawyers, said it expected victory and that it won’t take the court’s advice as winning means Hanmi Semiconductor will have to pay for all legal fees.

This is not the pair’s first legal battle. In 2018, Hanmi Semiconductor filed a patent lawsuit claiming Genesem infringed on its patent related to the semiconductor package loading table machine (patent number 0396982). It won that suit and Genesem paid 80 million won. However, that patent has since expired.

Hanmi Semiconductor has also filed a trade secret suit against an employee who moved to Genesem but that case was dropped.
