Summary: Düsseldorf Local Division order in Maxeon Solar Pte. Ltd.'s infringement action against Aiko Energy entities and others concerning EP 3 065 184 B1 (solar panel technology). The court ordered Maxeon to provide security for the defendants' legal costs and expenses (R. 158 RoP) given Maxeon's difficult financial situation in the solar sector, finding that the risk of Maxeon being unable to pay costs outweighed Maxeon's procedural rights. The security ceiling was set at EUR 200,000 based on the EUR 2,000,000 combined value of the dispute, with allocation between defendant groups.
