BENNAMANN SERVICES LTD currently manages 3 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 3 distinct examiners and art units. This ratio between actions, examiners, and art units indicates a decentralized prosecution profile where each matter is being reviewed in a unique technical and administrative context.
CASTELLANO, STEPHEN J is identified as the busiest examiner for the portfolio, currently handling 1 pending office action. Since there are 3 pending office actions in total and 3 distinct examiners, no single examiner is managing more than 1 case. This lack of concentration suggests that the company's current patent applications are being evaluated independently across different specialized groups within the patent office.
For practitioners, the involvement of multiple art units means that prosecution strategies may need to be tailored to the specific standards and tendencies of each group. With CASTELLANO, STEPHEN J and the other examiners each handling 1 pending office action, there is no central point of contact for the portfolio. This distribution requires diligent coordination to maintain consistency in the company's overall patent strategy.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 1 (33%) |
| Multi-statute (no §101) | 2 (67%) |
