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

Analysis

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.
