Osaka Soda Co. Ltd. has 5 pending office actions in Chemistry & Materials. The matters involve 5 examiners across 4 art units, indicating broad examiner coverage with some shared art-unit assignments.
KOPEC, MARK T is the busiest examiner, with 1 pending matter. The current record does not identify a dominant examiner, so counsel’s main coordination task is maintaining consistency across matters that may share technical examination environments.
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 (20%) |
| §102 only | 1 (20%) |
