Paul Wurth S.A. has 5 pending office actions in Chemistry & Materials. The matters involve 4 examiners and 3 art units, indicating overlap at both assignment levels.
ALDAZ CERVANTES, MAYELA RENATA is the busiest examiner with 2 pending matters. That examiner relationship offers an opportunity for coordinated review, while the art-unit distribution calls for separate consideration of unit-specific practice.
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 only | 1 (20%) |
| §101 + other | 1 (20%) |
| §103 only | 1 (20%) |
