On July 17, 2024, the National Intellectual Property Administration made three invalidity decisions, all declaring the patent validity of Ningde New Energy Technology Co., Ltd. for 'An electrode sheet and a lithium-ion battery containing the electrode sheet' (Patent No: ZL201410782528.9) represented by Junzhichuan, thus making a total of five successful defenses of this patent right. This patent is the subject of litigation, with a first-instance compensation amount of 30 million yuan. In the past three years, this patent has been challenged for validity five times; the reasons for invalidation are numerous, involving Article 33, and Section 3 and 4 of Article 26, and Sections 2, 3, and 4 of Article 22 of the Patent Law, among others. The evidence types for invalidation requests are extensive, ranging from patent literature, books and journals, webpage timestamps, to expert testimony, and various inspection reports issued by appraisal institutions, etc.; during the oral hearings, the requesting party even specially invited multiple witnesses to testify. In the face of such a daunting challenge from the invalidation requestors, the Junzhichuan team remained undaunted and confident, relying on its strong technical and patent expertise to dismantle each of the five invalidation attacks one by one, demonstrating Junzhichuan's top-notch professional strength and business capabilities. Notably, the first two invalidation cases were selected as among the top ten patent reexamination invalidation cases of 2022. In the future, Junzhichuan will continue to regard the entrusted responsibility of clients as its own duty and fully safeguard the intellectual property business of its clients.
