Sinopec Dalian Research Institute Of Petroleum And Petrochemicals Co. Ltd. has 4 pending office actions in the Chemistry & Materials technology area. These actions are distributed across 4 distinct examiners and 3 distinct art units. This distribution shows a relatively broad prosecution front for the company within its primary technology area. The presence of 4 distinct examiners for 4 pending actions means that no single examiner has a dominant influence over the current portfolio, which may help mitigate the risk of a single difficult examination style affecting multiple applications.
TAM M NGUYEN is the busiest examiner, currently handling 1 busiest examiner pending action. While there are 4 pending office actions in total, the workload is spread evenly, as the busiest examiner only manages 1 of them. The use of 3 distinct art units suggests that the company is navigating several different technical classifications simultaneously. Practitioners should be prepared to manage different sets of examiner guidelines across these 3 distinct art units to ensure consistent protection for the company's chemical and material innovations.
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 |
|---|---|
| §112 only | 1 (25%) |
| Multi-statute (no §101) | 3 (75%) |
