  "account": "The Mannheim Local Division of the Unified Patent Court dismissed a patent infringement lawsuit brought by SK Nexilis against Solus Advanced Materials, finding that Solus' product did not infringe SK Nexilis' patent. The lawsuit, which began in 2025, centered on the interpretation of the Rpc(Peak Count Roughness) value, a measure of surface roughness for copper foil used in secondary batteries. The relevant patent claim specified that the number of valid peaks within a 4mm sampling length must be between 10 and 100.
