Cummins Inc. has 71 pending office actions in Medical Devices & Mechanical Engineering. The portfolio spans 64 examiners and 39 art units, reflecting wide examiner distribution and substantial technical breadth.
TRAN, BINH Q is the busiest examiner, with 2 pending matters. The limited concentration means that examiner-specific coordination addresses only a small part of the record. A centralized process for art-unit monitoring and application-level issue tracking is therefore important.
Based on the USPTO statutory response window for each pending office action. 17 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. 17 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 + other | 4 (5%) |
| §103 only | 16 (22%) |
| §102 only | 9 (12%) |
| §112 only | 1 (1%) |
| Double-patenting only | 3 (4%) |
| Double-patenting + other | 2 (3%) |
| Multi-statute (no §101) | 38 (52%) |
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.
