Maxterial Inc. currently has 4 pending office actions within the Chemistry & Materials technology area. These matters are distributed among 4 distinct examiners, meaning each examiner is currently responsible for a single action. This ratio between actions and examiners suggests a broad exposure to different individual examiner perspectives.
The portfolio spans 3 distinct art units, indicating some technical concentration despite the variety of examiners. YE, XINWEN is listed as the busiest examiner with a single pending office action. This workload is shared by the other distinct examiners involved in the company's current prosecution efforts.
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.
| Bucket | Cases |
|---|---|
| §103 only | 1 (25%) |
| Double-patenting only | 1 (25%) |
| Multi-statute (no §101) | 2 (50%) |
