Cummins Inc. has 69 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed among 64 distinct examiners, which shows a high degree of diversity in the individuals reviewing the company's applications. The prosecution activity is spread across 33 distinct art units, reflecting a wide technical range for the portfolio.
The busiest examiner, TRAN, BINH Q, is currently managing 3 busiest examiner pending actions. This is a small portion of the 69 total pending office actions, indicating that the workload is not heavily concentrated with any single examiner. With 64 distinct examiners involved, the company encounters a wide variety of examination styles across 33 distinct art units. Practitioners should be prepared for unique examiner feedback on almost every application, as there is very little examiner overlap. This distribution suggests that the company's innovations are being reviewed by many different technical groups, requiring a flexible and tailored approach to each of the 69 pending office actions.
Based on the USPTO statutory response window for each pending office action. 18 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. 18 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 (6%) |
| §103 only | 15 (23%) |
| §102 only | 6 (9%) |
| Double-patenting only | 3 (5%) |
| Double-patenting + other | 2 (3%) |
| Multi-statute (no §101) | 35 (54%) |
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.
