What are the requirements for recording an assignment of a patent or patent application?

To record an assignment of a patent or patent application, the following requirements must be met:

• The assignment must be in writing.
• It must be signed by the assignor (the person or entity transferring ownership).
• The document must identify the patent or application by number.
• The assignment must be submitted to the USPTO along with the required fee.

According to MPEP 301: “An assignment relating to a patent must be submitted to the USPTO for recordation as an absolute requirement for enforcing the patent or application against third parties.” This recordation provides constructive notice to the public of the assignment.
