Enerpac Tool Group Corp. has 3 pending office actions in Medical Devices & Mechanical Engineering. The matters are assigned to 3 distinct examiners and 3 distinct art units, so each matter follows a separate examination path.
RIEGELMAN, MICHAEL A is the busiest examiner, with 1 pending matter. Matter-specific prior-art review and response planning will be more useful than relying on a shared examiner or art-unit approach.
Difficulty is derived from the rejection statutes on the most recent pending office action. §101-driven and multi-statute cases are graded Hard; §112-only and obviousness-type double-patenting cases are graded Easy; everything else is Medium. "Unknown" means we have not yet parsed a statute for that office action.
| Bucket | Cases |
|---|---|
| §103 only | 2 (67%) |
