SK Nexilis, an investment company in SKC's copper foil business, won all counts in a jury verdict in an ongoing patent infringement lawsuit in the United States. With this, Solus Advanced Materials (hereinafter Solus Advanced Materials) was officially recognized as having infringed SK Nexilis' patents.
On the 26th, SK Nexilis said that on the 22nd local time, a jury at the U.S. District Court for the Eastern District of Texas returned a verdict recognizing SK Nexilis' claims on all five asserted patents in a patent infringement lawsuit against Solus Advanced Materials.
The jury found that Solus Advanced Materials infringed SK Nexilis' core copper foil patent technologies that contribute to improving a battery's energy density and charging efficiency. The patents cover technology that, in the copper foil manufacturing process, stably controls the shape and physical properties of the product to reduce wrinkling and tearing, and prevents structural damage during charging and discharging, thereby enhancing the battery's durability and performance.
With the jury verdict concluded, a final ruling is expected to be handed down soon. Depending on the judgment, follow-up procedures will proceed regarding the amount of damages and the scope of royalty payments.
An SK Nexilis official said, "This jury verdict is the first case in which a U.S. court has officially recognized that SK Nexilis' research and development achievements accumulated over decades were unlawfully infringed in an actual industrial setting," and added, "We plan to respond actively to the upcoming final ruling and related procedures."
