15 pending office actions • 5 art units • 12 examiners • 0 of 15 (0%) have an AI response strategy ready • 30 patents granted in the last 365 days
Chengdu Monolithic Power Systems Co., Ltd. has 16 pending office actions in Semiconductors, Circuits & Optics. The portfolio spans 12 distinct examiners and 5 distinct art units, showing that prosecution is distributed across multiple technical and examiner assignments rather than concentrated in one unit.
RETEBO, METASEBIA T is the busiest examiner, with 2 pending matters. The spread supports matter-by-matter tracking of claim scope, cited art, and response timing, while the limited concentration with the busiest examiner suggests that no single examiner controls most of the active workload.
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.
| Bucket | Cases |
|---|---|
| §103 only | 3 (20%) |
| §102 only | 4 (27%) |
| Multi-statute (no §101) | 8 (53%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
