Zhejiang University has 64 pending office actions in Biotechnology & Pharmaceuticals. The portfolio involves 64 distinct examiners across 57 distinct art units, showing complete examiner dispersion and broad technical distribution. This structure creates a substantial coordination task, because similar subject matter may receive different examination treatment across the docket.
BUTCHER, BRIAN M is the busiest examiner, with 1 pending matter. No repeated examiner concentration appears in the supplied data, so counsel should rely on systematic portfolio controls rather than a concentrated examiner playbook. Centralized tracking of claim scope, specification support, and art-unit-specific issues can improve consistency while preserving matter-level flexibility.
Based on the USPTO statutory response window for each pending office action. 19 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. 19 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 only | 3 (5%) |
| §101 + other | 15 (24%) |
| §103 only | 12 (19%) |
| §102 only | 1 (2%) |
| §112 only | 14 (23%) |
| Multi-statute (no §101) | 17 (27%) |
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.
