Arkema Inc. has 16 pending office actions in Chemistry & Materials. The actions involve 16 distinct examiners and 14 distinct art units, showing a broad examiner spread across a smaller set of art units.
ZEMUI, NATHANAEL T is the busiest listed examiner, with 1 pending action. The listed examiner workload does not materially concentrate the portfolio, so prosecution planning may benefit from matter-specific review rather than a single-examiner strategy.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 | 10 (56%) |
| §102 only | 1 (6%) |
| Multi-statute (no §101) | 7 (39%) |
