Velan Inc. manages 3 pending office actions within the Medical Devices & Mechanical Engineering technology area. These actions are distributed across 3 distinct examiners and 3 distinct art units. This one-to-one ratio between 3 pending office actions, 3 distinct examiners, and 3 distinct art units indicates that each matter is being handled in a completely different technical group by a different individual. There is no overlap in the current prosecution of these 3 pending office actions.
TIETJEN, MARINA ANNETTE is one of the examiners involved, currently overseeing 1 pending office action. This 1 pending office action is one of the 3 pending office actions in the portfolio. The involvement of 3 distinct art units suggests that the company's mechanical filings are technically diverse. For practitioners, this means that each of the 3 pending office actions requires a completely independent strategy tailored to the specific 1 distinct art unit and 1 distinct examiner involved. The 3 pending office actions represent a decentralized prosecution effort where each application must be advanced on its own merits within the Medical Devices & Mechanical Engineering field. Practitioners should focus on the specific standards of each of the 3 distinct art units to be successful.
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%) |
| §112 only | 1 (33%) |
| Multi-statute (no §101) | 1 (33%) |
