China University of Petroleum (east China) has 6 pending office actions in Chemistry & Materials. The matters are distributed across 6 distinct examiners and 6 distinct art units, with each pending action represented by a separate examiner and technical unit in the profile.
CEPLUCH, ALYSSA L is the busiest examiner, with 1 pending matter. The evenly distributed assignments make consistent claim-development standards and matter-level monitoring more practical than a strategy centered on one recurring examiner.
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.
