Maxeon, a Singapore-based solar module manufacturer, has filed two separate patent infringement lawsuits against South Korea-based competitor Hanwha Qcells and Norway-headquartered REC Solar Holdings AS in the US District Court for the Eastern District of TexasThe alleged patent violations are related to an unspecified TOPCon solar cell technology.

“The company has a global patent portfolio of over 1,650 granted patents and more than 330 pending patent applications protecting the innovations underpinning its IBC, Shingled Hypercell, and TOPCon technologies,” Maxeon said, without providing further details.

In late March, Maxeon filed a similar lawsuit against Canadian Solar. Maxeon had previously sued Canadian Solar in Japan for patent infringement in 2020. In that lawsuit, Maxeon alleged that Canadian Solar Japan infringed upon its Japan Patent No. JP6642841B2, which is related to its shingled solar modules. The two companies reached a settlement agreement in April 2022.

In November 2023, Maxeon sued Chinese competitor Aiko Solar Energy, as well as wholesaler Memedo GmbH, for alleged patent infringement regarding a specific design related to the architecture of back contact solar cells.

And in June 2023, Maxeon had filed a lawsuit against Tongwei Solar in Germany for the alleged infringement of its European patent for shingled solar cell technology.
