Kemira Oyj has a prosecution workload of 8 pending office actions in the Chemistry & Materials technology area. These actions are distributed among 7 distinct examiners and spread across 5 distinct art units. VERA, ELISA H is the busiest examiner for the portfolio, managing 2 pending office actions.
The use of 7 distinct examiners for the pending office actions indicates a decentralized prosecution process. This requires the company to manage multiple professional relationships and adapt to a variety of examination styles. The complexity is increased by the involvement of 5 distinct art units, meaning the company's technology is being reviewed across several different specialized divisions of the USPTO.
VERA, ELISA H's role as the busiest examiner with 2 pending office actions provides a point of concentration in the portfolio. The other pending office actions are handled by different examiners. Practitioners must navigate the procedural nuances of the art units while ensuring consistency across the 8 pending office actions. This level of diversity in examiners and art units suggests a broad patent strategy within the Chemistry & Materials sector.
Based on the USPTO statutory response window for each pending office action. 1 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 | 1 (17%) |
| §103 only | 1 (17%) |
| Multi-statute (no §101) | 4 (67%) |
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.
