Gs Yuasa International Ltd. has 58 pending office actions in Chemistry & Materials. The matters involve 54 examiners and 26 art units, reflecting a large and widely distributed examiner docket with repeated concentration in technical groups. The difference between pending matters and examiners shows limited examiner repetition, while the smaller art-unit count provides a stronger basis for technical portfolio coordination.
HANYON, SAMANTHA LEE is the busiest identified examiner, with 2 pending matters. That repeated assignment may support focused review of examination treatment, but it is only one part of a broad docket. Counsel should combine art-unit monitoring with consistent claim strategy, disclosure support, and centralized tracking of office-action responses.
Based on the USPTO statutory response window for each pending office action. 17 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. 17 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 (5%) |
| §103 only | 34 (59%) |
| §102 only | 5 (9%) |
| §112 only | 1 (2%) |
| Multi-statute (no §101) | 14 (24%) |
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.
