57 pending office actions • 30 art units • 50 examiners • 0 of 57 (0%) have an AI response strategy ready • 57 patents granted in the last 365 days
Mitsubishi Gas Chemical Company, Inc. has 61 pending office actions in Chemistry & Materials. The docket reaches 54 distinct examiners and 31 distinct art units, indicating a large and widely distributed prosecution operation across chemical and materials technologies.
SHUKLA, KRUPA is the busiest examiner, with 2 pending matters. The limited concentration at the busiest examiner means that portfolio oversight cannot depend on a small group of recurring examiner relationships. Counsel should maintain coordinated technology, disclosure, and claim-support guidance while allowing responses to reflect the particular art unit and examiner handling each matter.
The breadth of the docket also increases the value of structured tracking for cited references, amendment themes, and unresolved issues. A centralized review can identify recurring prosecution concerns without treating the separate examination assignments as interchangeable.
Based on the USPTO statutory response window for each pending office action. 11 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. 11 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 (2%) |
| §103 only | 19 (33%) |
| §102 only | 1 (2%) |
| Double-patenting only | 1 (2%) |
| Double-patenting + other | 4 (7%) |
| Multi-statute (no §101) | 31 (54%) |
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.
