BEIJING RESEARCH INSTITUTE OF CHEMICAL INDUSTRY, CHINA PETROLEUM & CHEMICAL CORPORATION has 7 pending office actions in Chemistry & Materials. The matters involve 6 distinct examiners across 5 art units, showing broad distribution with some repeated examination context.
SAWYER, JENNIFER C is the busiest examiner, with 2 pending actions. Those matters may support coordinated analysis of chemical claim scope and recurring prior-art issues, while the remaining actions require examiner- and art-unit-specific preparation.
The spread of assignments makes centralized docket review important. Counsel should align technical terminology and disclosure positions across the portfolio, but preserve response strategies that reflect each examination record.
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 | 2 (29%) |
| §112 only | 1 (14%) |
| Double-patenting + other | 1 (14%) |
| Multi-statute (no §101) | 3 (43%) |
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.
