ACT_7940/2024

Hamburg Local Division final decision in infringement action (with revocation counterclaim) concerning a patent for reducing latency in wireless network data packet processing (claimed as standard-essential). Both the infringement claim and the revocation counterclaim were dismissed. The court found non-infringement after interpreting the patent claims with reference to the description and drawings (Art. 69 EPC), concluding that the defendant's Cisco products did not implement the claimed DMA-based simultaneous header writing mechanism. The revocation counterclaim also failed. Costs were split: claimant to bear 40%, defendants 60%.
