Kuraray Co., Ltd. has 69 pending office actions in Chemistry & Materials. The matters involve 64 distinct examiners across 31 distinct art units, showing broad examiner dispersion and recurring activity within technical classifications. The portfolio benefits from coordinated chemistry and materials issue tracking alongside matter-specific prosecution review.
CHOI, PETER Y is the busiest examiner, with 2 pending matters. That cluster is small relative to the full docket, so it supports targeted examiner analysis without defining portfolio priorities. Counsel should use art-unit groupings to identify related claim, disclosure, and prior-art questions.
Based on the USPTO statutory response window for each pending office action. 26 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. 26 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 + other | 1 (1%) |
| §103 only | 35 (50%) |
| §102 only | 2 (3%) |
| §112 only | 2 (3%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 2 (3%) |
| Multi-statute (no §101) | 27 (39%) |
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.
