SK Nexilis Co. Ltd. has 4 pending office actions in Chemistry & Materials. The matters involve 3 distinct examiners and 3 distinct art units, indicating separate art-unit paths with one examiner handling more than one action.
ZACHARIA, RAMSEY E is the busiest examiner, with 2 pending matters. That assignment merits coordinated review for recurring claim language, cited references, and technical explanations. The other examiner assignments still require matter-specific responses tailored to their respective 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 | 1 (25%) |
| Multi-statute (no §101) | 3 (75%) |
