Is the patent evaluation report still valid after patent modification?

Invalid. According to the relevant information of the patent investigation report, the original patent evaluation report is inconsistent with the revised patent, so it is invalid. Patent, literally, refers to the exclusive right. The word "patent" comes from Latin Litteraepatentes, which means open letters or open documents. It is a certificate used by medieval monarchs to issue certain privileges, and later refers to the exclusive rights certificate signed by the British king himself.
