Where can I find the phone number to check patent maintenance fee status?
The MPEP does not directly provide the phone number for checking patent maintenance fee status in section 2570. However, it does provide guidance on where to find this information: “See MPEP § 1730 for the telephone number.”
To find the correct phone number:
- Refer to MPEP § 1730
- Look for the contact information for the Maintenance Fee Branch
It’s important to note that phone numbers may change over time, so always refer to the most up-to-date version of the MPEP or the official USPTO website for the current contact information.
