Chemetall GmbH has 7 pending office actions in Chemistry & Materials. The portfolio spans 5 distinct examiners and 5 distinct art units, indicating distribution across several examination groups, with some examiner or art-unit assignments supporting more than one pending matter.
ZHENG, LOIS L is the busiest examiner, with 3 pending matters. This examiner represents the largest identified concentration of work, making examiner-specific issue tracking important. Counsel should still maintain cross-portfolio coordination because the remaining matters are distributed across distinct examination relationships and technical groups.
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 | 2 (29%) |
| Multi-statute (no §101) | 5 (71%) |
