IHI Corporation has 29 pending office actions in Chemistry & Materials. Those actions involve 29 distinct examiners and 19 distinct art units. The one-to-one relationship between actions and examiners indicates that each pending matter is assigned to a different examiner, while the art-unit distribution shows that some units handle multiple matters.
ZAMORA ALVAREZ, ERIC J is the busiest examiner, with 1 pending matter. No examiner carries more than that single matter in the supplied data. A prosecution team should therefore treat the portfolio as broadly distributed, using application-level tracking and art-unit review rather than relying on a concentrated examiner strategy.
Based on the USPTO statutory response window for each pending office action. 7 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. 7 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 (4%) |
| §103 only | 10 (36%) |
| §102 only | 2 (7%) |
| Double-patenting + other | 1 (4%) |
| Multi-statute (no §101) | 14 (50%) |
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.
