Two new patent infringement complaints have been filed in Texas district courts associated to photo voltaic panel patents. LONGi first filed towards JinkoSolar on Jan. 17 for half-cut cell infringement, and Jinko filed towards Waaree on Feb. 7 for TOPCon infringement.
LONGi holds U.S. Patent No. 9,515,214 associated to “Photo voltaic Battery Module and Manufacturing Technique Thereof,” which principally covers divided (half-cut) photo voltaic cells. The patent was initially assigned to Mitsubishi in 2012. Mitsubishi assigned the ‘214 patent to LONGi in 2020. In LONGi’s patent infringement grievance, it lists each half-cut mannequin below Jinko’s panel portfolio, regardless in the event that they use PERC or TOPCon know-how. LONGi is requesting damages for the infringement and an order to completely cease additional infringement.
Individually, Jinko’s submitting towards Waaree continues the TOPCon battle within the business. Jinko owns Patent No. 11,824,136 associated to “Photo voltaic Cell, Manufacturing Technique Thereof, and Photovoltaic Module,” which was issued in 2023. Jinko has additionally filed a complaint against Toyo for infringing on the ‘136 patent. Jinko is in search of damages for the infringement and an order for Waaree to completely cease additional infringement on the TOPCon patent.
Almost each main photo voltaic panel producer, even First Photo voltaic, has a declare on TOPCon panel know-how. Court cases will probably proceed over the subsequent few years.
