Patent evaluation report requires the patentee or interested party to make a request to China National Intellectual Property Administration Patent Office, pay a certain fee (within 3,000 yuan of design), and then wait for receiving the report. The content of the evaluation report mainly records whether your patent conforms to the relevant provisions of the Patent Law and its detailed rules for implementation, and whether it is novel, creative and practical after retrieval. The evaluation report can be used as evidence for the court or the reexamination board to hear relevant infringement or invalid cases.
