Technology area: Medical Devices & Mechanical Engineering
2 pending office actions • 1 art units • 2 examiners • 0 of 2 (0%) have an AI response strategy ready • 3 patents granted in the last 365 days
CRRC Qingdao Sifang Co., Ltd. holds a patent portfolio in the Medical Devices & Mechanical Engineering technology area. There are 2 pending office actions and 2 distinct examiners currently active. Despite having multiple examiners, all prosecution is occurring within 1 distinct art unit, which suggests a consistent technical focus for these filings.
The busiest examiner for the portfolio is SANDHU, AMRITBIR K, who is responsible for 1 busiest examiner pending office action. Since the workload is distributed among the distinct examiners, the Medical Devices & Mechanical Engineering area provides the framework for these pending actions. This concentration in a distinct art unit allows for a specialized approach to the technical merits of the applications. The company's strategy must account for the specific standards of the Medical Devices & Mechanical Engineering area while managing separate examiner interactions.
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%) |
