This case at the Unified Patent Court concerns an infringement action and a counterclaim for revocation involving European Patent No. EP 2 819 131 B1. Ericsson claimed that AsusTek infringed the patent by selling laptops containing specific Intel Wi-Fi modules. Ericsson sought damages and an order requiring AsusTek to provide detailed sales information. AsusTek countered by seeking revocation of the patent, arguing it contained added matter, lacked novelty, and inventive step. Proceedings included a decision on costs contingent on the outcome, a dismissed injunction request, and detailed procedural submissions. During oral proceedings, Ericsson withdrew their rectification claim. Ultimately, the court found in favor of AsusTek, revoking the patent and dismissing the infringement claim.
