What is the fee for recording a patent assignment with the USPTO?

The fee for recording a patent assignment with the USPTO depends on the method of submission:

• For electronic submissions through the Electronic Patent Assignment System (EPAS), the fee is currently $0, as stated in 37 CFR 1.21(h)(1).
• For non-electronic submissions (e.g., mail or fax), the fee is set forth in 37 CFR 1.21(h)(2).

It’s important to note that fees may change over time. As stated in MPEP 302.06: “Customers should check the current fee schedule on the Office website before submitting documents for recordation.”

Additionally, no fee is required for recording certain government interest documents, as specified in 37 CFR 3.41(b).
