Tigo Energy has filed a new lawsuit against APsystems in addition to its current ongoing case. The complaint includes four new patent infringement claims, as well as an additional claim from a patent asserted in the previously filed lawsuit. The complaint was filed in the United States District Court for the Northern District of California. The total number of Patents-in-Suit in both cases now stands at six. The complaint includes all APsystems legal entities in the U.S. as well as in China.
The new complaint alleges that APsystems’ Sunspec-compliant products infringe the following U.S. patents: 8,653,689, 9,584,021, 9,966,848, 10,333,405, and 8,933,321. The complaint centers around various systems and methods used in the PV module rapid shutdown unit.
Tigo amended its prior complaint to remove all claims against APsystems’ parent company, Zhejiang Yuneng Technology Co. APsystems said it views this as a positive development and confirmation that there is no evidence that its parent company has committed any act that Tigo can accuse of infringement.
