Epirium Bio Inc. has 2 pending office actions in Biotechnology & Pharmaceuticals. The matters are handled by 2 distinct examiners within 1 distinct art unit, combining examiner variation with a shared technical assignment.
CHENG, KAREN is the busiest examiner, with 1 pending matter. The common art-unit setting may support comparison of claim treatment and technical framing, but each examiner's reasoning should still be addressed directly in the corresponding response.
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 |
|---|---|
| §112 only | 1 (50%) |
