Mitsubishi Heavy Industries Ltd. faces 100 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are handled by 95 distinct examiners, showing a relationship where most examiners handle a single case. This high number of 95 distinct examiners suggests that the company must navigate a vast array of individual examiner preferences and styles across its applications.
The 100 pending office actions are distributed across 47 distinct art units. This breadth of 47 art units highlights the diverse mechanical and medical applications within the portfolio. BURKE, THOMAS P is the busiest examiner, yet he only manages 2 pending office actions. The prosecution workload is decentralized, as the busiest examiner accounts for only 2 of the total pending actions. This distribution requires a modular approach to prosecution management across the various technical groups.
Based on the USPTO statutory response window for each pending office action. 27 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. 27 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 | 5 (5%) |
| §101 + other | 6 (6%) |
| §103 only | 34 (33%) |
| §102 only | 7 (7%) |
| §112 only | 5 (5%) |
| Multi-statute (no §101) | 44 (43%) |
| No statute on record | 1 (1%) |
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.
