Kingfa Sci & Tech Co. Ltd. has 8 pending office actions in Chemistry & Materials. The matters are distributed across 7 distinct examiners and 7 distinct art units, indicating a broad docket with limited numerical overlap among assignments. The docket therefore requires coordination, but the data does not point to a single examination center.
USELDING, JOHN E is the busiest examiner, with 2 pending matters. That examiner has the largest stated assignment, while the remaining matters are spread across other examiners and art units. Counsel may benefit from reviewing the two matters together for consistent claim terminology and response positions, without assuming that the same approach applies to the rest of the portfolio.
The matching examiner and art-unit figures suggest that most examination paths are distinct. A centralized docket review can identify related technical themes, track deadlines, and avoid inconsistent amendments. Substantive strategy should remain tied to each office action because the available data does not identify common rejections or shared claim sets.
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 | 3 (38%) |
| §103 only | 3 (38%) |
| Multi-statute (no §101) | 2 (25%) |
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.
