3 pending office actions • 3 art units • 3 examiners • 0 of 3 (0%) have an AI response strategy ready • 2 patents granted in the last 365 days
Mitsubishi Chemical UK Limited has 3 pending office actions within the Chemistry & Materials technology area. These actions are distributed among 3 distinct examiners, meaning that each pending matter is receiving an independent review. This distribution requires the company to manage three separate sets of examiner expectations within its Chemistry & Materials portfolio.
The 3 pending office actions are spread across 3 distinct art units, indicating a high degree of technical and organizational dispersion. PROCTOR, CACHET I is the busiest examiner, managing 1 busiest examiner pending action. With 3 distinct examiners and 3 distinct art units involved, no single individual or group has a dominant influence over the 3 pending office actions. This structure suggests that the company's current patent applications cover a wide range of specialized topics within the Chemistry & Materials field.
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 |
|---|---|
| §103 only | 1 (33%) |
| Multi-statute (no §101) | 2 (67%) |
