6 pending office actions • 1 art units • 5 examiners • 0 of 6 (0%) have an AI response strategy ready • 2 patents granted in the last 365 days
Salts Healthcare Limited has 5 pending office actions in Medical Devices & Mechanical Engineering. Those matters involve 4 distinct examiners but only 1 distinct art unit, indicating that the portfolio’s prosecution activity is distributed among examiners within a common technical examination setting.
YANG, CHENG FONG is the busiest examiner, with 2 pending matters. The remaining work is therefore spread across other examiners, while the shared art-unit setting may make consistent claim terminology and argument strategy useful across the portfolio. Counsel should review whether recurring issues are examiner-specific or reflect a common art-unit approach, then coordinate responses without assuming that one response will resolve every matter.
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 (17%) |
| Double-patenting + other | 1 (17%) |
| Multi-statute (no §101) | 4 (67%) |
