On September 5, 2023, the China National Intellectual Property Administration issued an invalidation decision No. 563314, declaring that the patent rights owned by Beijing Down Science and Technology Development Ltd. and titled "A Vibration Shock Composite Sensor with Improved Low-Frequency Characteristics" are all invalid.

 

This case is the second invalidation of the patent, and the first-instance judgment of civil infringement of the patent involved has determined that the infringement was established (the client has appealed). In the case of tight time and heavy tasks, the Hengbo team accepted the client's entrustment. After careful analysis and prior decision-making, and extensive searches and full preparations, Hengbo filed an invalidation request on behalf of the client, and finally the invalidation decision No. 563314 decided the patent was invalid in its entirety.

 

The decision held that: If there are multiple distinguishing technical features between the technical solution of a claim and the closest reference document, but some of the distinguishing technical features have been disclosed by reference documents in the same field, and their role is the same as that of solving actual technical problems in this patent, and other distinguishing technical features are easily imagined by those skilled in the art based on the disclosure of the prior art, then the technical solution in the claim does not involve inventive step.

 

According to legal provisions, if the patentee is dissatisfied with the invalidation decision, he can file an administrative lawsuit with the Beijing Intellectual Property Court within three months.
