Could a《专利申请受理通知书》(Notice of Acceptance of Patent Application) be used in support of a patent claim?
No. A Notice Acceptance of Patent Application can only prove that the patent application has been received by the National Intellectual Property Administration, PRC. It could not be used for the purpose of proving that the application has been granted for registration (You may refer to the below screenshot for a sample of the Notice of Acceptance of Patent Application.)
