Nouryon Chemicals International B.V. has 16 pending office actions in Chemistry & Materials. The matters are assigned to 16 distinct examiners across 10 distinct art units, showing complete examiner separation and a more concentrated distribution among technical groups.
ROLLAND, ALEX A is the busiest examiner, with 1 pending matter. Because no examiner handles more than one pending action in the supplied data, portfolio coordination should focus on technical consistency and art-unit patterns rather than repeated examiner practice.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 5 (31%) |
| Double-patenting + other | 2 (12%) |
| Multi-statute (no §101) | 9 (56%) |
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.
