As we all know, China's utility model patents are not examined and can be authorized without judging their novelty and creativity. But this kind of patent right is very unstable. If there is a prior patent, then your rights can be invalidated. When you take advantage of this unstable right to conduct business activities, it is likely to infringe upon the legitimate prior patent rights of others, thus causing infringement disputes.
You'd better take the patent certificate to China National Intellectual Property Administration for novelty retrieval, and the Patent Office will make a reference judgment on the stability of your patent right. Know how to do it when implementing it, and know how to deal with related problems when encountering it.
