China University of Petroleum (east China) maintains a focused portfolio in the Chemistry & Materials technology area with 6 pending office actions. These actions are handled by 6 distinct examiners, resulting in a one-to-one ratio between pending matters and the individuals reviewing them. This distribution indicates that the university does not currently have multiple applications before any single examiner in this set. The portfolio is active across 5 distinct art units, showing that even with a small number of actions, the technical subject matter is spread across several specialized groups.
The busiest examiner for the university is DOYLE, BRANDI M, who is currently overseeing 1 pending office action. Because each of the 6 pending office actions is assigned to a different examiner, the prosecution strategy must be tailored to 6 different individual perspectives. The presence of 5 distinct art units for only 6 actions suggests that the university's research in chemistry and materials is technically diverse rather than concentrated in a single niche. This requires the legal team to navigate the specific procedural nuances of multiple USPTO divisions simultaneously.
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 |
|---|---|
| §101 + other | 2 (33%) |
| §103 only | 1 (17%) |
| §112 only | 1 (17%) |
| Double-patenting + other | 1 (17%) |
| Multi-statute (no §101) | 1 (17%) |
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.
