FAN, WEIHUA is the busiest examiner, with 3 pending actions. Counsel should treat that examiner assignment as a priority workstream and use the two-art-unit structure to coordinate technical arguments, claim terminology, and supporting evidence.
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 |
|---|---|
| §101 + other | 2 (22%) |
| §112 only | 6 (67%) |
| Multi-statute (no §101) | 1 (11%) |
