What are the consequences of an improper signature on patent correspondence?

Improper signatures on patent correspondence can have serious consequences. While the MPEP 502.02 doesn’t explicitly list all consequences, it emphasizes the importance of proper signatures:

Correspondence filed in the Office by applicants and other parties must be signed by the applicants or other party, or by a registered patent attorney or agent of record in the patent application or patent.

The potential consequences of an improper signature include:

• Rejection or return of the correspondence
• Delays in processing the application or request
• Potential loss of rights or missed deadlines
• Requirement for ratification or confirmation of the signature
• In severe cases, charges of fraud or inequitable conduct

To avoid these issues, it’s crucial to ensure all signatures comply with USPTO requirements as outlined in 37 CFR 1.4 and MPEP 502.02. When in doubt, consult with a registered patent attorney or agent to verify proper signature practices.
