Enerpac Tool Group Corp. has 5 pending office actions in the Medical Devices & Mechanical Engineering technology area. These 5 actions are assigned to 5 distinct examiners, resulting in a unique examiner for each pending case. The portfolio spans 4 distinct art units, which is a high number of units for only 5 actions. The 4 distinct art units suggest that the company's mechanical engineering innovations are technically diverse and are being reviewed by several different specialized groups within the office.
RIEGELMAN, MICHAEL A is the busiest examiner, managing 1 pending office action. This matches the distribution of 5 distinct examiners for 5 pending office actions. For the practitioner, this means coordinating with 5 different individuals across 4 distinct art units. Even with a small number of 5 pending office actions, the presence of 4 distinct art units requires attention to the different procedural and technical expectations of each specialized group. The workload of 1 pending office action for RIEGELMAN, MICHAEL A is the standard for this portfolio.
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 (40%) |
| Double-patenting only | 1 (20%) |
| Multi-statute (no §101) | 2 (40%) |
