W. R. Grace & Co.-conn. has 7 pending office actions in Chemistry & Materials. The matters involve 6 distinct examiners across 5 distinct art units, so the workload is distributed across several examination channels.
LEE, RIP A is the busiest examiner, with 2 pending matters. The limited concentration supports separate examiner review, while the art-unit spread calls for matter-specific analysis rather than a single portfolio-wide response approach.
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 | 2 (29%) |
| §112 only | 1 (14%) |
| Multi-statute (no §101) | 4 (57%) |
