318 pending office actions • 48 art units • 195 examiners • 0 of 318 (0%) have an AI response strategy ready • 277 patents granted in the last 365 days
Becton, Dickinson and Company maintains a large prosecution presence in the Medical Devices & Mechanical Engineering technology area with 320 pending office actions. These actions are distributed among 196 distinct examiners, which reflects the scale of the company's innovation. This volume requires a management system to track 320 pending office actions across many individuals.
The company's work spans 49 distinct art units, showing a broad technical footprint within the Medical Devices & Mechanical Engineering field. LOPEZ, SEVERO ANTON P is the busiest examiner, currently managing 10 busiest examiner pending actions. While SEVERO ANTON P LOPEZ is the most active, his 10 busiest examiner pending actions represent only a small fraction of the total 320 pending office actions.
For practitioners, the ratio of 196 distinct examiners to 320 pending office actions means that many examiners are handling multiple cases. The involvement of 49 distinct art units further highlights the diversity of the portfolio, as each unit may have its own specific examination culture. Managing 10 busiest examiner pending actions for a single examiner like SEVERO ANTON P LOPEZ is a key task within the larger 320 pending office actions.
Based on the USPTO statutory response window for each pending office action. 99 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. 99 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 | 7 (2%) |
| §101 + other | 19 (6%) |
| §103 only | 117 (37%) |
| §102 only | 10 (3%) |
| §112 only | 11 (3%) |
| Double-patenting only | 5 (2%) |
| Double-patenting + other | 16 (5%) |
| Multi-statute (no §101) | 132 (42%) |
| No statute on record | 1 (0%) |
