1864.04 Agent’s Right To Act [R-08.2012]
Any agent entitled to practice before the receiving Office where the international application was filed may represent the applicant before the international authorities ( PCT Article 49 ).
If for any reason, the examiner needs to question the right of an attorney or agent to practice before the International Preliminary Examining Authority (IPEA), the USPTO roster of registered attorneys and agents should be consulted. If the international application was filed with a receiving Office other than the United States, Form PCT/IPEA/410 may be used by the requesting IPEA to ask the receiving Office with which the international application was filed, whether the agent named in the international application has the right to practice before that Office.
The PCT Article and Regulations governing the right to practice are PCT Article 49 and PCT Rule 83.
