Donaldson Company, Inc. is managing 30 pending office actions in the Chemistry & Materials technology area. These actions are distributed among 25 distinct examiners and 14 distinct art units. CLEMENTE, ROBERT ARTHUR is the busiest examiner, with 5 pending office actions currently under review. The 30 pending actions are spread across 14 distinct art units, reflecting the technical range within the chemistry and materials sector.
With 25 distinct examiners involved, the company interacts with many officials, though CLEMENTE, ROBERT ARTHUR handles 5 of the actions. This distribution suggests a diversified prosecution strategy with some concentration under the busiest examiner. The busiest examiner pending count of 5 is a portion of the 30 total pending actions. The involvement of 14 distinct art units shows that the company's technology is being evaluated by multiple technical sections of the patent office. CLEMENTE, ROBERT ARTHUR is the busiest examiner for these 30 pending office actions, managing 5 of the current matters. This structure indicates that the workload is distributed across 25 distinct examiners.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 |
|---|---|
| §103 only | 6 (19%) |
| §102 only | 1 (3%) |
| §112 only | 1 (3%) |
| Double-patenting only | 6 (19%) |
| Double-patenting + other | 5 (16%) |
| Multi-statute (no §101) | 12 (39%) |
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.
