Alfa Laval Corporate AB has 21 pending office actions in the Chemistry & Materials technology area. These actions are handled by 11 distinct examiners, which is a portion of the total pending actions. The portfolio is concentrated within 5 distinct art units, suggesting a focused technical range for these chemistry related applications. With only 5 distinct art units involved, the prosecution process is likely more centralized than portfolios with a higher art unit count, despite the involvement of 11 distinct examiners for the 21 pending office actions.
The busiest examiner, COOLEY, CHARLES E, is managing 7 pending office actions. This represents a significant portion of the total pending actions for the company. For a practitioner, the influence of COOLEY, CHARLES E is substantial, as this one examiner handles a large share of the pending workload. The concentration of 21 pending office actions within 5 distinct art units allows for a more streamlined strategy that focuses on the specific requirements and precedents of those few specialized groups. Managing 7 pending office actions with a single examiner requires a highly consistent technical narrative.
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 (29%) |
| §112 only | 2 (10%) |
| Multi-statute (no §101) | 13 (62%) |
