DuPont de Nemours Inc. has 32 pending office actions in Chemistry & Materials. The docket spans 26 examiners and 18 art units, indicating broad distribution across both examination personnel and technical units.
REDDY, KARUNA P is the busiest examiner, with 4 pending matters. That examiner carries a meaningful subset of the docket, but the pending-action total remains distributed across many other examiner assignments. Counsel should prioritize coordination for the matters before this examiner without treating that assignment as representative of the full portfolio.
The difference between the pending-action count and the examiner count shows that some examiners handle multiple matters. The difference between examiner and art-unit counts also indicates that several examiners operate within at least some shared technical units. A centralized docket process should therefore combine examiner-level monitoring with art-unit-specific review.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 | 1 (4%) |
| §103 only | 10 (37%) |
| §112 only | 2 (7%) |
| Double-patenting + other | 3 (11%) |
| Multi-statute (no §101) | 11 (41%) |
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.
