6 pending office actions • 4 art units • 6 examiners • 0 of 6 (0%) have an AI response strategy ready • 9 patents granted in the last 365 days
24M Technologies Inc. has 6 pending office actions in the Chemistry & Materials technology area. These actions are spread across 4 distinct art units, indicating that the company's technical filings are distributed among several specialized groups within the patent office. The prosecution involves 6 distinct examiners, meaning that every pending office action is being handled by a different individual.
CULLEN, SEAN P is the busiest examiner for the portfolio, currently responsible for 1 pending office action. Since there are 6 distinct examiners for the 6 pending office actions, each examiner is responsible for a single action. The 4 distinct art units suggest that while the examiners are all different, some of them are working within the same technical divisions to review the filings in Chemistry & Materials.
This distribution requires the company to maintain 6 separate examiner relationships while navigating the specific procedural nuances of the 4 distinct art units. The lack of concentration under any single examiner, including CULLEN, SEAN P, suggests a prosecution landscape where each application is evaluated independently. Practitioners must manage 6 different sets of examiner preferences across the Chemistry & Materials sector.
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 |
|---|---|
| §102 only | 1 (17%) |
| Multi-statute (no §101) | 4 (67%) |
| No statute on record | 1 (17%) |
