Solugen Inc. has 9 pending office actions in Chemistry & Materials. The matters involve 9 distinct examiners and 8 distinct art units, showing broad distribution across examiners with some art-unit overlap. BREEN, KIMBERLY CATHERINE is the busiest examiner, with 1 pending office action.
The near correspondence between pending matters and examiner assignments indicates that the portfolio is not centered on a recurring examiner. The lower art-unit count indicates that some matters share examination environments, which may provide a basis for monitoring common technical and procedural treatment. Counsel should preserve matter-specific response plans while using art-unit groupings to identify recurring claim interpretation or prior-art issues. Examiner history remains relevant for individual interviews and amendments, but the profile supports a broader art-unit review as the more practical coordination tool.
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 | 3 (33%) |
| §112 only | 1 (11%) |
| Double-patenting only | 1 (11%) |
| Multi-statute (no §101) | 4 (44%) |
How the docket's pending cases split across USPTO tech-center bands.
