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.
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.
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.
If a utility model/design patent application has been granted the utility model/design patent registration certificate, the patentee or interested parties could follow the instructions to apply for patent evaluation report at http://www.cnipa.gov.cn/jldxx/1062986.htm .
If your patent has been assigned/altered, please provide a certified copy of the patent register.

No. You need to submit each of your invention patents, utility models and/or design patents separately for verification.
