38 pending office actions • 11 art units • 36 examiners • 0 of 38 (0%) have an AI response strategy ready • 35 patents granted in the last 365 days
Cardiac Pacemakers Inc. has 42 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are assigned to 40 distinct examiners, which indicates a high ratio of examiners to cases. This distribution suggests that the company's prosecution efforts are spread widely across many different individuals at the USPTO.
The portfolio is active in 11 distinct art units, showing a significant technical breadth within the Medical Devices & Mechanical Engineering field. ROANE, AARON F is the busiest examiner, holding 3 busiest examiner pending actions. While AARON F ROANE is the most active, his 3 busiest examiner pending actions represent only a small portion of the total 42 pending office actions.
For practitioners, managing 40 distinct examiners across 11 distinct art units requires a coordinated approach to ensure consistency. The fact that most examiners are only handling one case for the company means that 42 pending office actions involve many unique perspectives. Strategy must balance the specific tendencies of AARON F ROANE against the diverse requirements of the 11 distinct art units.
Based on the USPTO statutory response window for each pending office action. 11 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. 11 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 | 3 (8%) |
| §101 + other | 12 (32%) |
| §103 only | 9 (24%) |
| §102 only | 1 (3%) |
| §112 only | 1 (3%) |
| Double-patenting + other | 1 (3%) |
| Multi-statute (no §101) | 11 (29%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
