On December 01, 2025, the China National Intellectual Property Administration (CNIPA) issued the Examination Decision on Request for Invalidation No. 610172, declaring that the patent rights of Beijing Subang Network Technology Co., Ltd., titled “Elevator Intelligent Group Control System and Allocation Method” are entirely invalid.

After being commissioned by the client, our Hengbo team conducted thorough and meticulous preparation and ultimately successfully invalidated the patent.

The Decision held that: if the technical solution claimed differs from the closest prior art document by certain distinguishing features, and part of those distinguishing features have already been disclosed in other prior art documents, while the remaining distinguishing features constitute common technical means used by a person skilled in the art to solve the same technical problem, then it is generally considered that the prior art provides motivation to apply said distinguishing features to the closest prior art document to solve its technical problem. Thus, the claimed invention lacks inventiveness in view of the combination of the closest prior art document, other prior art documents, and common technical means in the field.

According to the laws, that patentee may complain to the Beijing Intellectual Property Court within 3 months in case not satisfied with the Examination Decision.
