Sunnybrook Research Institute has 6 pending office actions within the Biotechnology & Pharmaceuticals technology area. These 6 actions are distributed among 6 distinct examiners, meaning each pending matter is being handled by a different person. This distribution requires the institute to engage with six unique examiners, adapting its strategy to the specific preferences of each official.
The portfolio is active across 5 distinct art units. CWERN, JONATHAN is the busiest examiner for the company, currently managing 1 pending office action. Since each of the 6 examiners is responsible for exactly 1 action, the workload is evenly spread across the 5 art units and the assigned personnel. This lack of examiner overlap across the 6 actions means that the institute's success depends on the individual determinations of six different officials. Managing these diverse relationships across 5 art units is essential for the institute's biotechnology and pharmaceutical intellectual property goals.
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 |
|---|---|
| §101 + other | 1 (14%) |
| §103 only | 2 (29%) |
| Multi-statute (no §101) | 4 (57%) |
How the docket's pending cases split across USPTO tech-center bands.
