Hollingsworth & Vose Company has 8 pending office actions in Chemistry & Materials. The matters involve 7 distinct examiners across 4 distinct art units, showing a substantial workload distributed among examiners but grouped within a smaller set of technical units. Some examiner repetition is present, although no single examiner dominates the profile.
MCKENZIE, THOMAS B is the busiest examiner, with 2 pending matters. Counsel should use the shared art-unit structure to identify recurring claim and materials issues, while tailoring arguments to each examiner’s treatment of the record. Centralized review of specification support and amendment consequences may help avoid inconsistent positions across the pending matters.
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 | 4 (44%) |
| §112 only | 1 (11%) |
| Double-patenting + other | 2 (22%) |
| Multi-statute (no §101) | 2 (22%) |
