Ch Biotech R&D Co. Ltd. has 18 pending office actions in Biotechnology & Pharmaceuticals. The portfolio spans 16 distinct examiners and 11 distinct art units, showing substantial distribution across examination resources. The difference between pending matters and examiner assignments indicates some examiner-level overlap, while the art-unit spread reflects multiple technical channels.
BARBER, KIMBERLY is the busiest examiner, with 3 pending matters. That concentration is material within the supplied examiner distribution and supports reviewing those matters together for recurring objections, claim language, and disclosure positions. The remaining matters require coordination across the wider examiner and art-unit network.
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 | 1 (6%) |
| §112 only | 4 (24%) |
| Double-patenting only | 1 (6%) |
| Double-patenting + other | 8 (47%) |
| Multi-statute (no §101) | 3 (18%) |
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.
