7 pending office actions • 1 art units • 6 examiners • 0 of 7 (0%) have an AI response strategy ready • 1 patents granted in the last 365 days
Salts Healthcare Limited maintains a portfolio with 7 pending office actions, all located within 1 distinct art unit. This indicates a high degree of technical specialization in Medical Devices & Mechanical Engineering, as all active matters are being processed by the same administrative group. However, the workload is distributed among 6 distinct examiners, which introduces a variety of individual perspectives into the prosecution process.
CHENG FONG YANG is the busiest examiner for this entity, currently managing 2 pending actions. This makes them the only examiner with multiple active matters, as the remaining actions are spread across the other examiners. While the 1 distinct art unit provides a consistent technical baseline, the high number of examiners relative to the 7 pending office actions suggests that the company must tailor its arguments to many different individual styles. Successfully managing these matters requires addressing the specific feedback of the 6 distinct examiners involved.
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.

|---|---|
| §103 only | 1 (14%) |
| Double-patenting + other | 1 (14%) |
| Multi-statute (no §101) | 5 (71%) |
