Daiichi Kigenso Kagaku Kogyo Co. Ltd. has 5 pending office actions in Chemistry & Materials. The matters involve 5 examiners across 4 art units, showing that examiner participation is broader than art-unit participation.
HOBAN, MATTHEW E is the busiest examiner, with 1 pending office action. No examiner has more than that stated action count, so counsel may find greater value in comparing files within shared art units than in pursuing one examiner-centered strategy.
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%) |
