US Court Rules In JinkoSolar’s Favor In Hanwha Patent Case

• JinkoSolar claims it has received a favorable ruling in the Hanwha Q Cells patent case in the US
• It said the US Court of Appeals for the Federal Circuit has concluded that JinkoSolar's products do not infringe a patent asserted by Hanwha Q Cells
• According to JinkoSolar, the facts were so clear to the Federal Circuit that it did not issue a written opinion

Chinese integrated solar PV manufacturer JinkoSolar Holding Co., Ltd. has received a favorable ruling in the patent infringement case filed by South Korean solar panel maker Hanwha Q Cells.

The company announced that the US Court of Appeals for the Federal Circuit has issued a Rule 36 summary affirmance, agreeing with the conclusion drawn by the International Trade Commission (ITC), that 'JinkoSolar's products do not infringe a patent asserted by Hanwha Q Cells' (see Good News For JinkoSolar In Hanwha Patent Case).

JinkoSolar stated, "The facts are so clear in the case that the Federal Circuit did not issue a written opinion."

Welcoming the said decision, JinkoSolar's Chairman and CEO Xiande Li said, "Cases like these are a transparent attempt to disrupt business, but we remain steadfast in our commitment to innovation and product leadership."

In July 2021, LONGi Solar claimed the US Patent and Trademark Office (USPTO) issued a final written decision on an inter partes review (IPR) proceeding, declaring all of the patent claims in Hanwha's US Patent 8,933,525B2 as invalid (see North America PV Snippets: LONGi, Sunlight, PowerFlex).

Hanwha Q Cells accused JinkoSolar, LONGi Solar and REC Group of infringing on its patented passivation technology in March 2019 (see Hanwha Complains Of Patent Infringement).
