Dalhousie University has 3 pending office actions in Medical Devices & Mechanical Engineering. The actions are assigned to 3 distinct examiners and 3 distinct art units, so each matter follows a separate examination path.
NGUYEN, HIEN NGOC is the busiest examiner, with 1 pending matter. The assignments are evenly distributed, and the profile does not show concentration around one examiner or art unit. Counsel should manage each matter independently while coordinating any common technical disclosure or claim terminology.
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 (33%) |
| Multi-statute (no §101) | 2 (67%) |
