Should l Buy MAXN?
Maxeon Solar announced that it has filed a new patent infringement lawsuit against Aiko Solar before the Munich Regional Court I in Germany. The lawsuit accuses Aiko and its European distribution network of infringing Maxeon's core back contact solar technology patent EP2297789B1, specifically addressing Aiko's second-generation and third-generation BC solar module products currently sold in the European market. This lawsuit follows Maxeon's previous intellectual property protection actions against Aiko and its sales channel, including a 2023 complaint filed before the Mannheim Regional Court concerning infringement of Maxeon patent EP2297788, and a 2024 complaint before the Unified Patent Court Local Division in Dusseldorf regarding infringement of Maxeon patent EP3065184. All three patents belong to the same BC solar technology family. Maxeon is seeking a court order for Aiko and the other defendants to refrain from infringing activities, disclose sales data for the accused products, and compensate for damages. Maxeon also seeks the destruction of infringing inventory held in Germany. Maxeon has not only targeted Aiko's manufacturing and sales entities but has also named four German solar product distributors-Wattkraft GmbH & Co., DWH Solutions, Memodo and Tepto as co-defendants.
