How should applicants handle status inquiries for PCT applications?

For status inquiries regarding PCT applications, the MPEP provides specific guidance:

  • Inquiries relating to international applications filed under the Patent Cooperation Treaty (PCT) should be directed to the PCT Help Desk.
  • The MPEP states: Inquiries relating to international applications (PCT) … should be directed to the PCT Help Desk at 1-800-PTO-9199 or 571-272-4300.
  • The PCT Help Desk can provide information on the processing of international applications at the United States Receiving Office (RO/US), United States International Searching Authority (ISA/US), and United States International Preliminary Examining Authority (IPEA/US).

It’s important to use the correct channel for PCT-related inquiries to ensure accurate and timely information.
