China Patent Right Evaluation Report

China's Patent Law stipulates that where a patent infringement dispute involves a utility model patent or a design patent, the people's court or the relevant administrative department may require the patentee or the interested parties to submit the patent right evaluation report (or PRER for short) of the asserted patent, which is made by the CNIPA after searching, analyzing, and evaluating. The PRER could be used as evidence for the trial or dealing with patent infringement disputes. The alleged infringer may also voluntarily submit the PRER.
