Technology area: Biotechnology & Pharmaceuticals
26 pending office actions • 22 art units • 26 examiners • 0 of 26 (0%) have an AI response strategy ready • 17 patents granted in the last 365 days
Keio University has 25 pending office actions in Biotechnology & Pharmaceuticals. The matters are assigned to 25 examiners and 21 art units, reflecting a wide examination footprint across the technology area and a need for portfolio-level coordination.
MATTSON, SEAN D is the busiest examiner, with 1 pending matter. No single examiner accounts for a larger share in the supplied data, so the prosecution workload is dispersed across individual matters rather than concentrated with one examiner.
The art-unit distribution indicates that related biotechnology and pharmaceutical inventions may encounter different examination contexts. Counsel should preserve consistent support for recurring technical concepts while tailoring claim amendments and prior-art responses to each application’s assigned art unit.
Based on the USPTO statutory response window for each pending office action. 8 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. 8 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 (27%) |
| §103 only | 9 (35%) |
| Double-patenting + other | 2 (8%) |
| Multi-statute (no §101) | 8 (31%) |
