Suspension of person to person appointments.

I am suspending the person-to-person patent or trademark appointments for the duration of these special circumstances.  I will be working from home and monitoring the chat service. My chat hours will vary and will include some evenings.  I will also be working on updating help guides to answer basic questions.  I also recommend contacting the United States Patent and Trademark Office Inventor Assistance Center at  1-800-786-9199, or the Trademark Assistance Center via email at

Access to PubWEST and PubEAST will also not be available during these special circumstances.

If you have any questions please use our chat service.

Thank you,
