Dongwoo Fine-chem Co., Ltd. has 18 pending office actions in Chemistry & Materials. The matters involve 16 examiners across 12 art units, indicating a widely distributed docket with limited concentration at the examiner level and broad technical placement.
MERLIN, JESSICA M is the busiest examiner, with 3 pending office actions. Those matters form the clearest examiner-centered cluster in the available data, but the overall distribution means that most prosecution decisions must still account for distinct examiner and art-unit treatment.
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 |
|---|---|
| §101 + other | 1 (6%) |
| §103 only | 7 (39%) |
| §102 only | 1 (6%) |
| §112 only | 1 (6%) |
| Double-patenting + other | 1 (6%) |
| Multi-statute (no §101) | 7 (39%) |
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.
