Daihen Corporation has 7 pending office actions in Transportation, E-Commerce & Mechanical Systems. The portfolio involves 7 distinct examiners across 4 distinct art units. Every pending matter is therefore associated with a different examiner, while some technical units contain more than one matter.
EVANS, KARSTON G is the busiest examiner, with 1 pending matter. Since the busiest examiner handles only one matter, the practical management challenge is coordination across the examiner group rather than concentration with one reviewer. Counsel should still look for technical themes that can support consistent disclosure and claim treatment across the art units.
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 | 4 (57%) |
| Double-patenting + other | 1 (14%) |
| Multi-statute (no §101) | 2 (29%) |
