BEIJING RESEARCH INSTITUTE OF CHEMICAL INDUSTRY, CHINA PETROLEUM & CHEMICAL CORPORATION has 6 pending office actions in the Chemistry & Materials technology area. These actions are distributed among 6 distinct examiners and 5 distinct art units. MELISSA A RIOJA is the busiest examiner, managing 1 pending office action.
The distribution of 6 pending office actions across 6 distinct examiners means that every active matter is being reviewed by a different person. This high level of variety is mirrored in the 5 distinct art units involved. MELISSA A RIOJA handles 1 pending office action, which is consistent with the workload of the other examiners in the portfolio. Practitioners should be prepared for a wide range of examination styles.
The presence of 5 distinct art units further suggests that the portfolio covers a broad spectrum of technical topics within Chemistry & Materials. This decentralized structure requires a highly adaptable prosecution strategy to address the unique requirements of 6 different examiners. With 5 distinct art units for 6 pending office actions, there is very little overlap in the administrative or technical oversight of the portfolio.
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 (17%) |
| §112 only | 2 (33%) |
| Double-patenting + other | 1 (17%) |
| Multi-statute (no §101) | 2 (33%) |
