Arkray Inc. has 19 pending office actions in Chemistry & Materials. The matters are distributed among 17 examiners and 14 art units, indicating a broad prosecution footprint with repeated assignments at both the examiner and art-unit levels. The difference between pending matters and examiners shows that some examiners handle more than one matter, while the art-unit figure reflects further grouping.
QIAN, SHIZHI is the busiest examiner, with 3 pending matters. This is the most concentrated examiner relationship identified in the profile. Counsel can use that cluster to coordinate response timing and technical positions, while preserving separate strategies for matters assigned outside that examiner and art-unit grouping.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 (5%) |
| §101 + other | 5 (26%) |
| §103 only | 3 (16%) |
| Multi-statute (no §101) | 10 (53%) |
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.
