Evoco Limited has 2 pending office actions in the Chemistry & Materials technology area. These 2 actions are split between 2 distinct examiners and 2 distinct art units. This indicates that each pending matter is being examined in a different technical group by a different individual, reflecting a lack of technical overlap in the current filings.
Larissa Rowe Emrich is the busiest examiner for the portfolio, currently handling 1 pending office action. With only 2 pending actions total, Emrich is responsible for one of the company's current matters. The busiest examiner pending count of 1 shows that no single examiner is managing more than one case for this company at this time.
The use of 2 distinct art units for just 2 pending office actions highlights the technical diversity of these filings within the Chemistry & Materials field. Practitioners should be prepared for different examination approaches, as 2 distinct examiners are involved across different technical groups. This decentralized structure for a small portfolio means that the prosecution of each matter will likely proceed independently of the other.
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.

|---|---|
| Double-patenting + other | 1 (50%) |
