Technology area: Medical Devices & Mechanical Engineering
3 pending office actions • 2 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready • 11 patents granted in the last 365 days
Sulzer Management AG has 3 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are handled by 3 distinct examiners across 2 distinct art units. Chirag Jariwala is the busiest examiner, currently overseeing 1 pending action.
The distribution of 3 actions to 3 different examiners means that no single examiner has a majority of the pending workload. The 2 distinct art units involved suggest that the portfolio spans multiple technical specialties within the mechanical engineering field. Practitioners will need to tailor their strategies to the 3 individual examiners while accounting for the specific practices of the 2 art units.
Since Chirag Jariwala and the other examiners each manage 1 pending action, the portfolio's progress is not dependent on any one individual. This spread requires the legal team to maintain 3 active lines of communication. The goal is to achieve consistency in the 2 art units while responding to the unique feedback provided by each of the 3 examiners.
Based on the USPTO statutory response window for each pending office action. 1 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%) |
