Hindustan Petroleum Corporation Limited has 4 pending office actions in Chemistry & Materials. The matters involve 4 examiners across 4 art units, creating fully separate examination paths.
CORALLO, CATRIONA MARY is the busiest examiner with 1 pending action. Counsel should coordinate core chemistry terminology and disclosure positions, but prepare distinct arguments for each art unit and examiner.
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 (25%) |
| §102 only | 1 (25%) |
| Multi-statute (no §101) | 2 (50%) |
