Jingyuan Optoelectronics, an Epistar subsidiary, recently won a significant victory in patent litigation.
In April 2017, the Epistar subsidiary, filed a patent complaint alleging that Lowe’s Home Centers, LLC, and Sanan (Fujian Sanan Group Co., LTD.) infringed five of its LED patents including US Patents 6,346,771, 7,560,738, 8,492,780, 8,587,020, and 8,791,467.
Subsequently, Lowes and Sanan filed an invalidation request for the five Jingyuan Optoelectronics patents with the US Patent Office. The US Patent Office recently rejected all five patent invalidation requests. Therefore, the patent coverage of the five Jingyuan Optoelectronics patents is completely unaffected.
In the invalidation request, Lowe’s and Sanan questioned the patentability of the five patents. However, Jingyuan Optoelectronics clearly and in detail proved to the US Patent Office that the patents are novel and non-obvious, and these patents are worthy of patent protection.
On November 1, 2018, the court ruled that the US patents 8,791,467 and 7,560,738 were valid, and on November 20, 2018, the court ruled that US patents 6,346,771, 8,492,780 and 8,587,020 were valid. According to the relevant law, the claimant (Lowe’s and Sanan) could not appeal.
