What fees are required to correct a typographical error in a recorded assignment?

When correcting a typographical error in a recorded assignment document, fees are required. The MPEP 323.01(b) states:

The affidavit or declaration must be accompanied by a copy of the originally recorded papers, a cover sheet, and the required fee for each application or patent to be corrected (37 CFR 3.41).

The specific fee amount is set by 37 CFR 3.41. It’s important to note that:

• A separate fee is required for each application or patent affected by the correction.
• The fee amount may change, so it’s best to check the current USPTO fee schedule for the most up-to-date information.
