Battelle Memorial Institute has 75 pending office actions in Chemistry & Materials. The docket spans 72 examiners and 58 art units, indicating extensive prosecution activity across a wide set of examination channels and repeated assignments within some units.
MELENDEZ, ARMAND is the busiest examiner, with 2 pending matters. That limited concentration does not create a dominant examiner relationship for the overall docket. The principal management challenge is coordination across the many examiner and art-unit assignments, including consistent disclosure positions, claim language, and response practices for technically related matters.
Based on the USPTO statutory response window for each pending office action. 25 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. 25 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 | 7 (10%) |
| §103 only | 22 (31%) |
| §112 only | 4 (6%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 1 (1%) |
| Multi-statute (no §101) | 36 (50%) |
| No statute on record | 1 (1%) |
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.
