What is a requirement for recording an assignment at the PTO?

Recording an assignment at the United States Patent and Trademark Office (USPTO) requires the document to specifically identify the patents or applications being transferred by their patent or application numbers. This requirement serves to ensure clarity and prevent any ambiguity regarding what rights are being assigned. By including these numbers, the PTO can accurately update their records to reflect the new ownership, thereby maintaining the integrity of the patent registry.

While notarization can enhance the credibility of the document, it is not a strict requirement for recording an assignment. Similarly, while submissions can be made through various means, including online submission, the form of submission does not affect the validity of the assignment itself. Lastly, a statement from the inventor, while it may be helpful in certain contexts, is not a fundamental requirement for recording the assignment at the PTO. The primary requisite is that the document must clearly indicate the associated patents or applications by their specific identifying numbers.
