How does the USPTO examine for written description compliance?
The United States Patent and Trademark Office (USPTO) has specific procedures for examining written description compliance in patent applications. According to MPEP 2163.01:
“While the test or analysis of description requirement and new matter issues is the same, the examining procedure and statutory basis for addressing these issues differ.”
Examiners typically compare the claims to the specification and drawings as filed to determine if there is adequate support. If support is lacking, they may issue a rejection under 35 U.S.C. 112(a). The examination process involves a thorough review of the original disclosure to ensure it provides sufficient detail to show that the inventor possessed the full scope of the claimed invention at the time of filing.
