Technology area: Biotechnology & Pharmaceuticals
12 pending office actions • 6 art units • 12 examiners • 0 of 12 (0%) have an AI response strategy ready • 5 patents granted in the last 365 days
STEMCELL Technologies Canada Inc. manages a portfolio in the Biotechnology & Pharmaceuticals technology area, characterized by 11 pending office actions. These actions are distributed among 11 distinct examiners, indicating a broad engagement with patent office personnel. The portfolio is currently active across 6 distinct art units, which suggests a range of subject matter within the biotechnology sector.
BEHARRY, ZANNA MARIA is the busiest examiner for the company, though this examiner is only responsible for 1 pending office action. This distribution is notable because the 11 pending office actions are spread across 11 examiners, meaning no single examiner holds a majority of the workload. With 11 distinct examiners and 6 distinct art units, the company faces a variety of examination styles and art unit timelines. This level of activity provides a significant amount of data for comparing prosecution experiences across different segments of the Biotechnology & Pharmaceuticals field. The high number of distinct examiners relative to the 11 pending actions indicates a decentralized prosecution environment.
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 | 3 (25%) |
| §112 only | 1 (8%) |
| Double-patenting + other | 5 (42%) |
| Multi-statute (no §101) | 3 (25%) |
