On April 9, 2024, the China National Intellectual Property Administration issued the Invalidation Decision No. 561076, declaring that part of the patent rights entitled "Cabinet Opening Control Method, User Terminal And Computing Equipment, Computer Storage Medium" owned by Zhejiang Koubei Network Technology Co., Ltd. and Rajax Network Technology (Shanghai) Co., Ltd. were invalid.

After receiving the client's commission, Hengbo team conducted a lot of meticulous preparation work, including successfully pointing out the flaws in the other party's evidence and technical misunderstandings. Ultimately, the China National Intellectual Property Administration decided that part of the patent rights were invalid.

The decision holds that: if the independent claim has recorded all the necessary technical features to solve the technical problem, can solve the technical problem it is to be solved, and reflects the technical solution of the invention as a whole, then it does not lack the necessary technical features. If a person skilled in the art can implement the technical solution of this patent under the guidance of the disclosure of the specification and achieve the corresponding technical effect, then the specification is fully disclosed. To judge whether the features in the claims are clear, it should be analyzed from the perspective of a person skilled in the art whether the features are clear in the entire technical solution. If the statement of the claims is clear to a person skilled in the art, it will not cause the scope of protection of the claims to be unclear. If the technical solution protected by the claims has distinguishing features compared with the comparative document as the closest prior art, and the distinguishing features are not disclosed by other comparative documents, and there is no evidence that they belong to the common knowledge in the field, and the solution of the claim can obtain beneficial effects, then the solution protected by the claim has creativity.

According to the law, if the patent owner is dissatisfied with the invalidation decision, he or she may file an administrative lawsuit with the Beijing Intellectual Property Court within three months.
