4 pending office actions • 3 art units • 4 examiners • 0 of 4 (0%) have an AI response strategy ready
Muffin Incorporated Dba Cook Advanced Technologies currently has 4 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 3 distinct art units, showing that the company's medical technology portfolio is being reviewed by several different specialized groups at the USPTO. This distribution requires the practitioner to be familiar with the specific examination cultures of 3 distinct art units.
The workload is further divided among 4 distinct examiners, with LANGHALS, RENEE C acting as the busiest examiner for 1 of the pending office actions. Since there are 4 distinct examiners for 4 pending office actions, every active matter in this portfolio is being evaluated by a different individual. This lack of examiner overlap, combined with the spread across 3 distinct art units, indicates a decentralized prosecution environment. Practitioners must develop unique strategies for each of the 4 pending office actions, as there is no opportunity to leverage a relationship with a single examiner across multiple matters.
Based on the USPTO statutory response window for each pending office action. 2 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 + other | 1 (25%) |
| Multi-statute (no §101) | 2 (50%) |
