What information do I need to check a patent’s maintenance fee status online?

To check a patent’s maintenance fee status online, you need two pieces of information:

1. The patent number
2. The corresponding application number

The MPEP states: “Maintenance fee status information for a patent of interest can be obtained over the internet by entering the patent number and the corresponding application number in the appropriate spaces on the webpage available at https://fees.uspto.gov/MaintenanceFees.”

Make sure you have both these numbers ready before visiting the USPTO’s Maintenance Fee webpage to ensure a smooth and quick status check process.
