Nissan Chemical Corporation has 50 pending office actions in Chemistry & Materials. The docket reaches 41 examiners across 28 art units, indicating broad distribution across chemical examination assignments.
NELSON, MICHAEL B is the busiest examiner, with 3 pending matters. The small examiner concentration favors a portfolio process based on technical grouping and art-unit monitoring, supported by examiner-specific preparation for repeated assignments.
Based on the USPTO statutory response window for each pending office action. 10 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. 10 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 (2%) |
| §101 + other | 3 (7%) |
| §103 only | 14 (31%) |
| §102 only | 3 (7%) |
| Double-patenting + other | 3 (7%) |
| Multi-statute (no §101) | 21 (47%) |
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.
