Hansol Chemical Co., Ltd. has 8 pending office actions in Chemistry & Materials. The docket is spread across 8 distinct examiners and 6 distinct art units, combining complete examiner dispersion with some art-unit concentration.
NGUYEN, KHANH TUAN is the busiest examiner, with 1 pending matter. Portfolio oversight should therefore emphasize consistent technical positions across matters while allowing for different examination settings.
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 (12%) |
| §112 only | 2 (25%) |
| Multi-statute (no §101) | 5 (62%) |
