How do “critical feature” omissions affect enablement in patent claims?
Omitting critical features in patent claims can significantly impact enablement. The MPEP 2164.08(c) states:
“A feature which is taught as critical in a specification and is not recited in the claims should result in a rejection of such claim under the enablement provision section of 35 U.S.C. 112.”
This means that if a feature is described as essential for the invention to function in the specification but is not included in the claims, it may lead to an enablement rejection. The rationale is that without the critical feature, the claimed invention may not be operable or may require undue experimentation to practice. To avoid this issue, applicants should ensure that all critical features described in the specification are appropriately reflected in the claims, or provide clear evidence that the feature is not actually critical for the invention to function as claimed.
