Technology area: Chemistry & Materials
5 pending office actions • 4 art units • 5 examiners • 0 of 5 (0%) have an AI response strategy ready • 1 patents granted in the last 365 days
Yantai Zhenghai Magnetic Material Co. Ltd. has 5 pending office actions in Chemistry & Materials. Those matters involve 5 distinct examiners across 4 distinct art units, so the portfolio spans several examination assignments despite remaining within one technology area.
SIDDIQUI, ADIL ABDUL WAJID is the busiest examiner with 1 pending action. No examiner holds a majority of the pending work, which favors matter-specific preparation and limits the value of relying on one examiner-focused prosecution strategy.
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 |
|---|---|
| §112 only | 3 (60%) |
| Multi-statute (no §101) | 2 (40%) |
