Co2Pac Limited has 2 pending office actions in the Medical Devices & Mechanical Engineering technology area. These 2 actions are split between 2 distinct examiners. The portfolio is also divided between 2 distinct art units, meaning each action is being reviewed in a different technical group.
Stephen J Castellano is the busiest examiner with 1 pending office action. This distribution shows that the company's current medical device filings are being handled independently by different examiners and art units. With 2 pending office actions and 2 distinct examiners, there is no overlap in the personnel reviewing the company's applications. The 2 distinct art units further indicate that the 2 pending matters are being evaluated in separate technical contexts within the USPTO, requiring a unique strategy for each of the 2 actions.
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 (50%) |
| Multi-statute (no §101) | 1 (50%) |
