Regents of the University of Minnesota is managing 90 pending office actions in the Biotechnology & Pharmaceuticals technology area. These actions are distributed across 88 distinct examiners and 47 distinct art units. This indicates a large and diverse portfolio with many different individuals and specialized groups involved. The 47 distinct art units show that the university's research covers a vast array of technical classifications within the biotech and pharmaceutical sectors.
PATEL, RONAK C is the busiest examiner, with 2 pending office actions. The other pending actions are spread among the other distinct examiners. With 88 distinct examiners involved, the university faces a high degree of variability in how its applications are reviewed. The 47 distinct art units for 90 actions indicate that while some specialized groups handle multiple applications, the individual examiners within those groups are mostly unique. Practitioners must manage separate prosecution tracks, as the high number of examiners limits the ability to reuse successful negotiation tactics across the portfolio.
Based on the USPTO statutory response window for each pending office action. 27 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. 27 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 (11%) |
| §103 only | 23 (26%) |
| §112 only | 3 (3%) |
| Double-patenting only | 2 (2%) |
| Double-patenting + other | 7 (8%) |
| Multi-statute (no §101) | 42 (47%) |
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.
