Is patent novelty retrieval the work of patent agents or other institutions?

Patent novelty retrieval is not done by patent agencies. If you want to establish a project or evaluate it, you should go to the patent office or the novelty retrieval station of the government department, and they will issue a novelty retrieval report, which can be used for establishing a project and evaluating assets. However, it should be noted that the patent novelty retrieval report can only be used as a reference and has no legal effect.
