Solus Advanced Materials: "U.S. Court Decides to Proceed With Patent Infringement Lawsuit as Scheduled"

Court Dismisses SK Nexilis's Request to Consolidate Trade Secret Misappropriation Claims

Solus Advanced Materials announced on September 10 that the court has dismissed SK Nexilis's request to consolidate its trade secret misappropriation claim with the ongoing battery foil patent infringement lawsuit in the United States.

As a result of the court's decision, the ongoing patent infringement lawsuit will proceed as originally scheduled.

Previously, SK Nexilis had submitted an amended complaint to the U.S. District Court for the Eastern District of Texas last month, requesting an additional review of Solus Advanced Materials' alleged liability for trade secret misappropriation in connection with the ongoing patent infringement lawsuit.

In response, Solus Advanced Materials filed a rebuttal, arguing that SK Nexilis's claims lacked clear legal grounds and validity. The company asserted to the court that the additive recipes for copper foil manufacturing, electrolyte operation conditions, and drum management methods cited by SK Nexilis were technologies already widely used in the market and that there was no misappropriation of trade secrets.

The U.S. court determined that the plaintiff's additional trade secret misappropriation claims constitute a new matter distinct from the ongoing patent infringement lawsuit and decided that they should proceed separately.

Accordingly, at the trial on the patent infringement lawsuit scheduled for November, the additional trade secret misappropriation claims requested by SK Nexilis will not be addressed. Only Solus Advanced Materials' non-infringement claims and the validity of the opposing party's patent will be contested.
