32 pending office actions • 12 art units • 27 examiners • 0 of 32 (0%) have an AI response strategy ready • 36 patents granted in the last 365 days
Medtronic Vascular Inc. has 32 pending office actions in Medical Devices & Mechanical Engineering. The matters involve 27 distinct examiners and 12 distinct art units, showing broad examiner exposure across a sizable medical-device prosecution docket.
HEIN, DEVIN C is the busiest examiner, handling 2 pending matters. No single examiner accounts for a large concentration of the listed activity, so prosecution planning should emphasize consistent claim terminology, disclosure positions, and response quality across separate examination relationships. The art-unit distribution also supports maintaining technical issue maps by application, rather than assuming that one response strategy will transfer uniformly throughout the portfolio.
Based on the USPTO statutory response window for each pending office action. 12 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. 12 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 | 5 (16%) |
| §103 only | 11 (34%) |
| §102 only | 1 (3%) |
| Double-patenting only | 1 (3%) |
| Multi-statute (no §101) | 14 (44%) |
How the docket's pending cases split across USPTO tech-center bands.
