Edwards Lifesciences CardiAQ LLC manages a company patent portfolio in the Medical Devices & Mechanical Engineering technology area. The portfolio currently has 4 pending office actions. These actions are handled by 4 distinct examiners across 2 distinct art units. This distribution suggests that while each application has a unique examiner, there is significant technical overlap within the patent office departments.
The busiest examiner for this portfolio is YABUT, DIANE D, who is handling 1 busiest examiner pending office action. With 4 pending office actions and 4 distinct examiners, no single examiner dominates the workload. However, the use of only 2 distinct art units for 4 actions implies that multiple applications are being processed within the same technical units. For a practitioner, this means they must navigate the individual preferences of four different people, but they may find consistency in the broader art unit policies for the portfolio. This requires a balanced strategy that accounts for both individual examiner styles and shared art unit standards within the medical device field to ensure efficient prosecution.
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 + other | 1 (25%) |
| §103 only | 1 (25%) |
