Idemitsu Kosan Co.,ltd. has 80 pending office actions in Chemistry & Materials. The docket reaches 67 distinct examiners and 38 distinct art units, creating a broad prosecution footprint. This dispersion supports centralized issue tracking, but it also calls for local analysis of examiner treatment and art-unit expectations.
DEGUIRE, SEAN M is the busiest examiner, with 6 pending matters. The concentration is meaningful for that examiner’s assigned cases, yet it does not describe the entire docket. Counsel should separate examiner-specific patterns from broader Chemistry & Materials issues when prioritizing interviews, amendments, and appeal decisions.
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 | 3 (4%) |
| §103 only | 30 (37%) |
| §102 only | 2 (2%) |
| §112 only | 1 (1%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 6 (7%) |
| Multi-statute (no §101) | 38 (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.
