Technology area: Chemistry & Materials
14 pending office actions • 10 art units • 13 examiners • 0 of 14 (0%) have an AI response strategy ready • 6 patents granted in the last 365 days
Shofu Inc. has 15 pending office actions in the Chemistry & Materials technology area. These actions are assigned to 14 distinct examiners, meaning one examiner is handling multiple cases. COLLISTER, ELIZABETH A is the busiest examiner, with 2 pending actions.
The portfolio is spread across 11 distinct art units. This is a high number of units for only 15 pending office actions, suggesting a very diverse set of technical subjects. The ratio of 14 distinct examiners to the 15 pending office actions shows that almost every examiner is handling only one case.
With 11 distinct art units involved, the company's chemistry and materials work is being evaluated by many different specialized groups at the USPTO. The busiest examiner workload of 2 pending actions represents the only instance of workload concentration for the 15 pending office actions. This broad distribution across 14 distinct examiners and 11 distinct art units reflects a decentralized prosecution environment.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 | 8 (57%) |
| Double-patenting only | 1 (7%) |
| Multi-statute (no §101) | 5 (36%) |
