Sanden Corporation operates in the Medical Devices & Mechanical Engineering technology area. The company has 8 pending office actions. These actions are distributed among 8 distinct examiners, ensuring independent evaluation for each matter. This distribution suggests that the company's applications are subject to a wide variety of individual perspectives rather than being funneled to a small group of specialists.
The prosecution involves 4 distinct art units. This suggests that the company's innovations are being categorized into four different specialized groups. Practitioners must be prepared to address the specific nuances of these 4 units. The variety of art units indicates that the portfolio's technical scope is expansive, requiring expertise in multiple disciplines to effectively respond to office actions.
ESTEVEZ, DAIRON is the busiest examiner for the portfolio. This examiner is responsible for 1 pending office action. The busiest examiner pending count is 1, confirming that the workload is evenly split among the examiners. No single examiner has a concentrated influence over the current pending portfolio. Practitioners should focus on the individual requirements of each official involved.
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 |
|---|---|
| §103 only | 4 (57%) |
| Multi-statute (no §101) | 3 (43%) |
