As a utility model, although it has been granted a patent right, the stability of this patent right is not high, because there is no substantive examination procedure for the utility model, that is, the patent office granted you a patent right without examining whether your utility model application is really novel, creative and practical, which means it is very likely that someone has applied for the same patent before you, or that the same technology has been made public in the society. This is also the reason why the utility model gains the right faster. On the other hand, inventions have substantive examination procedures, which can only be obtained after retrieval, and patents can only be granted if there are no identical patents.
Therefore, the patent search report can make up for this deficiency to some extent. Although the Patent Office does not search for utility models when examining them, when you want to know whether your utility model is stable (that is, whether it will be invalidated by others in the future), you can search at your own expense.
Generally, most people who carry out this kind of retrieval are in tort litigation, and the content of the retrieval report is the list of comparative documents of the utility model and its basic information.
