Solus Advanced Materials wins European copper foil patent case
Solus Advanced Materials won a European patent case brought by SK Nexilis over copper foil used in batteries.
The case was heard by the Unified Patent Court’s Mannheim local division in Germany, and concerned Solus’s European subsidiary, Volta Energy Solutions.
The court found no patent infringement and dismissed SK Nexilis’s claim.
The dispute focused on how to measure a surface-roughness value called Rpc, which was specified in the patent.
The court rejected SK Nexilis’s proposed conversion method, saying it did not follow the patent’s wording and stated measurement rules.
SK Nexilis must pay €1.1 million in legal costs to Solus Advanced Materials.
The company said it would continue operating in Europe and responding to related cases that are still underway.
