There are three kinds of patent retrieval: paper retrieval, software retrieval and intellectual property retrieval.
Search before R&D: Before R&D, we can determine whether the technological innovation has been patented or patented by others through IncoPat's scientific and technological innovation information platform;
Novelty search before patent application: it can be determined whether the technical scheme is novel before application, so as to determine whether the technical scheme can apply for a patent;
Search to prevent infringement: through search, the possibility that products manufactured or sold fall into the scope of patent protection of others can be ruled out;
Evidence collection and retrieval in invalid procedures: the retrieved previously disclosed technology can be used as evidence to question the novelty and creativity of the other party's patent right in invalid procedures.
