What actions should an examiner take if claims are unclear or inadequately supported?
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.
According to MPEP 1874, if an examiner finds that claims are unclear or inadequately supported, they should take the following actions:
- Not proceed with the examination on those specific claims
- Inform the applicant of this opinion and provide reasons
- Check the appropriate box on the examination form
The MPEP states:
“The examiner should check the appropriate box if it is found that the description, claims or drawings are so unclear, or the claims are so inadequately supported by the description that no opinion could be formed as to the novelty, inventive step (nonobviousness) and industrial applicability of the claimed invention.”
This approach ensures that applicants are informed of issues preventing a meaningful examination and allows them to address these issues if they choose to pursue the application further.
