Regents of the University of Minnesota has 87 pending office actions in Biotechnology & Pharmaceuticals. The docket involves 87 examiners and 61 art units, showing complete examiner dispersion with recurring assignments at the technical-unit level. The scale and distribution favor centralized docket governance supported by art-unit-specific review.
SHEN, YANXIN NMN is the busiest examiner, with 1 pending action. No examiner has more than that amount in the supplied data, so portfolio strategy should not depend on a single examiner relationship. Consistent internal guidance and matter-level monitoring are more relevant operational priorities.
Based on the USPTO statutory response window for each pending office action. 21 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. 21 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 | 2 (2%) |
| §101 + other | 10 (12%) |
| §103 only | 22 (27%) |
| §102 only | 1 (1%) |
| §112 only | 4 (5%) |
| Double-patenting only | 2 (2%) |
| Double-patenting + other | 6 (7%) |
| Multi-statute (no §101) | 36 (43%) |
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.
