Hamilton Medical AG has 7 pending office actions in Medical Devices & Mechanical Engineering. The matters are distributed across 6 examiners and 3 art units, indicating broad examiner involvement within a smaller set of technical examination groups. This pattern favors centralized docket control paired with art-unit-specific analysis of recurring claim issues.
CHANG, THOMAS ZHU is the busiest examiner, with 2 pending matters. The concentration is limited to part of the portfolio, while the remaining matters are spread among other examiners. Counsel should identify common technical themes without assuming uniform examination treatment.
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 |
|---|---|
| §101 + other | 1 (14%) |
| §103 only | 2 (29%) |
| §112 only | 1 (14%) |
| Multi-statute (no §101) | 3 (43%) |
