N E Chemcat Corporation has 5 pending office actions in Chemistry & Materials. The matters span 5 distinct examiners and 4 distinct art units, combining broad examiner distribution with some overlap in technical examination groups.
HAILEY, PATRICIA L is the busiest examiner, with 1 pending matter. No examiner has a larger identified share, so counsel should use portfolio-level coordination without assuming a common examiner approach.
Based on the USPTO statutory response window for each pending office action. 2 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 (40%) |
| Multi-statute (no §101) | 3 (60%) |
