First Solar (FSLR) is taking no prisoners, irrespective of nationality. Filing a lawsuit for patent infringement in the U.S. District Court for the District of Delaware, the company claims that China's JA Solar and Corning (GLW) subsidiary, American Panel Solutions, are violating a U.S. patent related to manufacturing techniques for TOPCon crystalline silicon solar panels.
Shares of First Solar responded positively to the news, gaining more than 3.5% in Friday's trading session, only to give most of it back and close 1.45% higher.
