Why is document legibility important when submitting patent assignments?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

Document legibility is crucial when submitting patent assignments because:

1. The USPTO does not return recorded documents.
2. If the submitted copy is illegible, the recorded document will also be illegible.
3. Illegible documents may cause legal issues or complications in proving ownership.

The MPEP emphasizes this point: “If the copy submitted for recordation is illegible, the recorded document will be illegible. Accordingly, applicants and patent owners should ensure that only a legible copy is submitted for recordation.”

It’s the responsibility of the submitter to ensure that all documents are clear and readable to maintain accurate records of patent ownership.
