China University of Mining and Technology has 3 pending office actions in Chemistry & Materials. The record includes 3 distinct examiners and 3 distinct art units. DERUSSO, JOHN J is the busiest examiner, with 1 pending matter.
The matters are distributed one per examiner and art-unit pathway in the available record. This can increase the importance of application-specific analysis, particularly where materials, processing conditions, or related technical concepts receive different treatment in examination.
No single examiner is shown as carrying more than the stated 1 pending matter. Counsel can support consistent portfolio management by maintaining a shared technical vocabulary, while tailoring prior-art distinctions and amendment choices to each action’s reasoning.
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 | 1 (33%) |
| Multi-statute (no §101) | 2 (67%) |
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.
