Evoqua Water Technologies LLC has 7 pending office actions in Chemistry & Materials. These matters involve 6 examiners and 3 art units, indicating a portfolio distributed across several examination settings.
NORRIS, CLAIRE A is the busiest examiner, with 2 pending matters. That allocation is higher than the individual allocation reflected for the other examiners, but it remains one part of a multi-examiner record.
The presence of 3 art units makes technical grouping important for prosecution management. Counsel should separate art-unit-specific patterns from issues that recur across the water technology portfolio, while aligning arguments and amendments where the claim subject matter supports a common approach.
Based on the USPTO statutory response window for each pending office action. 3 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 3 of the docket's apps have a known mailing date.
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 |
|---|---|
| §103 only | 6 (75%) |
| Multi-statute (no §101) | 2 (25%) |
