Beijing E-Town Semiconductor Technology Co., Ltd. has 5 pending office actions in Chemistry & Materials. The matters involve 5 examiners and 4 art units, indicating separate examiner assignments with limited technical-assignment overlap.
ROST, ANDREW J is the busiest examiner, with 1 pending action. No examiner handles more than one listed matter, so counsel should use individualized prosecution analysis while coordinating terminology and technical disclosures across the related chemistry and materials docket.
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 | 3 (60%) |
| Multi-statute (no §101) | 2 (40%) |
