Sunnybrook Research Institute has 8 pending office actions in the Medical Devices & Mechanical Engineering technology area. These matters are distributed among 8 distinct examiners, meaning every pending case is being reviewed by a different person. This creates a diverse examination environment with no overlap in the personnel handling the current applications. The portfolio spans 7 distinct art units, reflecting a broad range of technical classifications within the Medical Devices & Mechanical Engineering sector.
CWERN, JONATHAN is the busiest examiner, currently managing 1 pending office action. With 8 distinct examiners and 7 distinct art units, practitioners must be prepared for a fragmented prosecution process that requires individual strategies for each pending matter. The high count of 7 distinct art units suggests that the institute's technology is being evaluated against a wide array of prior art and technical standards. Counsel should treat each of the 8 pending office actions as an independent effort, as the lack of examiner overlap means that arguments successful in one case may not influence the others.
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 (12%) |
| §103 only | 3 (38%) |
| Multi-statute (no §101) | 4 (50%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
