Technology area: Medical Devices & Mechanical Engineering
4 pending office actions • 2 art units • 3 examiners • 0 of 4 (0%) have an AI response strategy ready • 2 patents granted in the last 365 days
Alpheus Medical, Inc. focuses on Medical Devices & Mechanical Engineering with 3 pending office actions. These actions are spread across 2 distinct art units. This indicates that the company's medical technology spans different classification areas, requiring a strategy that can adapt to multiple technical standards.
There are 3 distinct examiners involved in the portfolio. ZHANG, LEI is the busiest, currently handling 1 pending office action. The use of three different examiners for the 3 pending actions suggests a lack of examiner overlap in the current cases. This distribution means that each application is receiving an independent review from a different official at the patent office.
Based on the USPTO statutory response window for each pending office action. 1 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 |
|---|---|
| §103 only | 1 (25%) |
| Double-patenting only | 1 (25%) |
| Multi-statute (no §101) | 2 (50%) |
