Stock Track | JinkoSolar Shares Plummet 12.81% After U.S. Rejects Patent Challenge Against First Solar

Stock Track

Jan 21

JinkoSolar's stock plummeted 12.81% during Tuesday's intraday trading, reflecting investor concerns over a recent legal setback.

The decline followed the U.S. Patent and Trademark Office's rejection of JinkoSolar's attempt to invalidate two patents held by competitor First Solar. The patents cover methods for manufacturing TOPCon crystalline silicon photovoltaic solar cells, a key technology in the solar industry.

JinkoSolar, along with Canadian Solar and Mundra Solar, had filed inter partes reviews in 2025 seeking to challenge First Solar's patents. The rejections, issued between November and December 2025, leave JinkoSolar vulnerable to ongoing patent infringement lawsuits filed by First Solar in Delaware. This legal uncertainty has weighed heavily on investor sentiment toward the solar panel maker.
