MilliporeSigma currently has 10 pending office actions in the Chemistry & Materials technology area. These 10 actions are handled by 10 distinct examiners, meaning every pending matter is being reviewed by a different individual. This lack of overlap is further reflected in the 8 distinct art units involved, showing a degree of technical variety across the portfolio. This distribution of 10 pending office actions across a range of examiners and units suggests a diverse research and development focus.
The busiest examiner, BARGEON, BRITTANY E, is responsible for 1 busiest examiner pending action. This confirms that no single examiner has a dominant role, as the 10 pending office actions are distributed among 10 distinct examiners. For practitioners, this means prosecution strategies must be individualized for each application across the 8 distinct art units. The distribution suggests that the portfolio covers different chemical and material sub-specialties. Managing 10 distinct examiners requires an organized approach to account for different sets of preferences and standards. The involvement of 8 distinct art units further defines the prosecution landscape, requiring expertise in multiple technical classifications.
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 + other | 2 (20%) |
| §103 only | 3 (30%) |
| §102 only | 1 (10%) |
| §112 only | 1 (10%) |
| Multi-statute (no §101) | 3 (30%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
