MilliporeSigma has 5 pending office actions in Chemistry & Materials. The matters are assigned to 5 distinct examiners and 5 distinct art units, indicating separate examination paths.
BARGEON, BRITTANY E is the busiest examiner, with 1 pending matter. Portfolio management should emphasize matter-specific arguments while checking that materials terminology, disclosure support, and amendment positions remain consistent where the technologies overlap.
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 + other | 2 (40%) |
| §103 only | 1 (20%) |
| §102 only | 1 (20%) |
| Multi-statute (no §101) | 1 (20%) |
