Donaldson Company, Inc. has 34 pending office actions in Chemistry & Materials. The matters are handled by 26 distinct examiners across 16 distinct art units, showing meaningful distribution with some repeated examiner assignments. The art-unit spread supports organizing review by technical grouping as well as by individual case.
CLEMENTE, ROBERT ARTHUR is the busiest examiner, with 6 pending matters. This is the clearest examiner-level concentration in the profile, making that examiner an appropriate focus for docket review and response consistency. Counsel should still account for the wider group of examiners and art units when setting portfolio priorities.
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 only | 1 (3%) |
| §103 only | 7 (21%) |
| §102 only | 1 (3%) |
| §112 only | 1 (3%) |
| Double-patenting only | 5 (15%) |
| Double-patenting + other | 4 (12%) |
| Multi-statute (no §101) | 14 (42%) |
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.
