What is the effect of altering an application after submitting an Oath/Declaration?

Altering an application after submitting an Oath/Declaration typically results in the invalidation of the original Oath/Declaration. The Oath/Declaration is a legal document affirming that the application was made in good faith and that the individual signing it believes themselves to be the original inventor. If there are changes to the application that alter its scope or content significantly, this can compromise the integrity of the Oath/Declaration, as it no longer accurately represents the claims and disclosures made at the time of signing.

Thus, an altered application may render the original Oath/Declaration ineffective, necessitating a new Oath/Declaration that aligns with the modified application to ensure compliance with patent laws and protect the rights associated with the application process. This practice helps maintain the accuracy and reliability of the patent system, ensuring that all representations made to the United States Patent and Trademark Office (USPTO) are truthful and complete.
