Primearth Ev Energy Co. Ltd. has 11 pending office actions in Chemistry & Materials. The matters involve 10 examiners across 7 art units, showing a broad prosecution workload with multiple examination channels and some examiner or technical overlap.
PILLAY, DEVINA is the busiest examiner, with 2 pending matters. That assignment warrants focused coordination, but the majority of the workload lies elsewhere. Counsel should combine portfolio-level review of recurring chemistry and materials issues with matter-specific analysis for each examiner and art unit.
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 | 7 (54%) |
| §112 only | 1 (8%) |
| Double-patenting only | 1 (8%) |
| Double-patenting + other | 1 (8%) |
| Multi-statute (no §101) | 3 (23%) |
