Inari Medical Inc. has 20 pending office actions in Medical Devices & Mechanical Engineering. The matters are assigned to 15 distinct examiners across 5 distinct art units, indicating substantial concentration within the art-unit structure and repeated examiner assignments.
NGUYEN, TUAN VAN is the busiest examiner, with 4 pending matters. That relationship is a clear coordination point for claim strategy and response arguments. The limited art-unit spread also supports centralized review of recurring examination issues across the portfolio.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 |
|---|---|
| §103 only | 10 (53%) |
| Double-patenting only | 1 (5%) |
| Double-patenting + other | 1 (5%) |
| Multi-statute (no §101) | 7 (37%) |
