Purple Cloud Development Pte. Ltd. has 7 pending office actions in Medical Devices & Mechanical Engineering. The matters are handled by 5 distinct examiners but all fall within 1 distinct art unit, creating examiner variation inside a common technical examination group.
PHAN, AN BACH is the busiest examiner, with 2 pending matters. Counsel can use the shared art-unit context to coordinate technical positions while comparing examiner-specific treatment across the assigned applications.
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 | 2 (29%) |
| §102 only | 1 (14%) |
| Multi-statute (no §101) | 4 (57%) |
