Daihen Corporation has 7 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed among 7 distinct examiners, resulting in a count of actions equal to the count of examiners. These examiners are located within 3 distinct art units, which suggests that the company's mechanical engineering filings are reviewed by a few specific technical groups at the patent office.
EVANS, KARSTON G is the busiest examiner for the portfolio. This examiner is managing 1 busiest examiner pending office action. The distribution of 7 actions across 7 different examiners indicates that no single examiner is handling multiple pending matters for the company. This decentralized approach across 3 distinct art units ensures that the prosecution of each application is independent of the others. The company must navigate the specific requirements of 3 different art units while dealing with 7 individual examiners. This distribution minimizes the impact of any single examiner's perspective on the overall portfolio.
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 | 3 (43%) |
| Double-patenting + other | 1 (14%) |
| Multi-statute (no §101) | 3 (43%) |
How the docket's pending cases split across USPTO tech-center bands.
