Medtronic Vascular Inc. maintains 30 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are handled by 26 distinct examiners, which suggests a broad distribution of the company's intellectual property across various examination desks. NGUYEN, TUAN VAN is identified as the busiest examiner, currently holding 2 busiest examiner pending actions. This volume of 30 pending office actions represents a significant active docket for the applicant.
The portfolio's activity spans 10 distinct art units, reflecting a variety of technical focuses within the medical device field. With 26 distinct examiners involved, the applicant must address a wide array of examiner perspectives and requirements. The distribution of 30 pending office actions across 10 distinct art units suggests that while there is some clustering of technology, the prosecution remains relatively dispersed. Coordinating responses for 30 pending office actions across 10 distinct art units and 26 distinct examiners requires a disciplined and organized legal strategy.
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.

|---|---|
| §101 + other | 4 (13%) |
| §103 only | 11 (37%) |
| Multi-statute (no §101) | 15 (50%) |
