What is the significance of recording patent assignments at the USPTO?

Recording patent assignments at the United States Patent and Trademark Office (USPTO) is crucial for several reasons:

• Legal Protection: It provides legal protection against subsequent purchasers or mortgagees.
• Official Recognition: The USPTO recognizes the assignee for all matters before the Office.
• Public Notice: It serves as public notice of the assignment.

According to MPEP 301:

An assignment relating to a patent must be recorded in the Patent and Trademark Office within 3 months from its date or prior to the date of a subsequent purchase or mortgage, in order to be effective against a subsequent purchaser or mortgagee.

Recording assignments promptly is essential to ensure full legal protection and recognition of ownership rights.
