China National Building Material Group Co. Ltd. has 3 pending office actions in Chemistry & Materials. Each action is associated with a distinct examiner and a distinct art unit, so the portfolio has no indicated concentration at either level.
LOTTER, DAVID E is the busiest examiner with 1 pending matter. Counsel should coordinate technical positions across the actions while preparing examiner-specific responses.
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%) |
