What is a patent evaluation report?

A patent evaluation report is a report issued by the National Intellectual Property Administration of the PRC (previously referred to as “SIPO”) based on a database search and analysis, which evaluates whether a utility model or design patent satisfy the legal requirements for granting a patent right.




Why do we need to provide the patent evaluation report together with design/utility model patent registration certificate?

Since utility model patent or design patent do not undergo substantial examination before the patent is granted, these types of patent rights are inherently unstable. To confirm whether a utility model or design patent satisfies to the legal requirements for granting a patent right, the patent evaluation report is required for authentication.




Who can apply for the patent evaluation report?

According to the patent law, only patentees and interested parties can apply for issuing a patent evaluation report by P.R.C. National Intellectual Property Administration (previously referred to as“SIPO”). (Note: The “interested parties” are parties that are qualified to file complaints or lawsuits with the patent administration authority just as a patentee.
