Silanna UV Technologies Pte. Ltd. has 6 pending office actions in Semiconductors, Circuits & Optics. The matters are assigned to 4 examiners across 4 art units, indicating a portfolio that spans multiple examination channels within the same technology area.
ANYA, IGWE U is the busiest examiner, with 2 pending matters. That assignment is a point for coordination, but it does not encompass the entire pending workload. Counsel should maintain examiner-specific analysis while looking for technical themes that recur across the four art units.
Based on the USPTO statutory response window for each pending office action. 1 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 (33%) |
| §102 only | 1 (17%) |
| Double-patenting + other | 1 (17%) |
| Multi-statute (no §101) | 2 (33%) |
