MILWAUKEE ELECTRIC TOOL Corporation maintains a large patent portfolio in the Medical Devices & Mechanical Engineering technology area. There are 264 pending office actions, indicating a very active and ongoing prosecution strategy. These actions are distributed among 173 distinct examiners, which means the company's applications are being reviewed by a broad cross-section of the USPTO's staff.
The activity is spread across 50 distinct art units. This wide distribution suggests that the company's innovations cover a diverse range of technical fields within mechanical engineering. For practitioners, managing 264 pending office actions across 50 art units requires a sophisticated approach to handle the varying technical and procedural requirements of many different USPTO divisions.
SHUTTY, DAVID G is the busiest examiner for the company, with 9 pending office actions. While this is the highest number for any single examiner, it represents only a small fraction of the 264 pending office actions in the total portfolio. The involvement of 173 distinct examiners highlights a decentralized prosecution environment where the company's overall success is not overly dependent on the decisions of a few individuals.
Based on the USPTO statutory response window for each pending office action. 77 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 77 of the docket's apps have a known mailing date.
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 |
|---|---|
| §101 only | 2 (1%) |
| §101 + other | 1 (0%) |
| §103 only | 99 (38%) |
| §102 only | 13 (5%) |
| §112 only | 8 (3%) |
| Double-patenting only | 6 (2%) |
| Double-patenting + other | 5 (2%) |
| Multi-statute (no §101) | 126 (48%) |
| No statute on record | 1 (0%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
