Technology area: Semiconductors, Circuits & Optics
8 pending office actions • 5 art units • 8 examiners • 0 of 8 (0%) have an AI response strategy ready • 10 patents granted in the last 365 days
Tianjin Sanan Optoelectronics Co., Ltd. has 8 pending office actions in Semiconductors, Circuits & Optics. The matters involve 8 distinct examiners across 5 distinct art units, so the examiner assignments are fully distributed while the art-unit assignments are more concentrated.
GHYKA, ALEXANDER G is the busiest examiner, with 1 pending matter. Because no examiner handles more than one listed matter, counsel should use portfolio-wide technical guidance without assuming uniform examiner treatment. The repeated art-unit assignments provide a basis for comparing art-unit practice and recurring claim issues.
For prosecution management, counsel can organize the matters first by art unit and then by examiner. That structure may support consistent responses to similar semiconductor issues while preserving the file-specific analysis required by each pending action.
Based on the USPTO statutory response window for each pending office action. 2 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 (25%) |
| Multi-statute (no §101) | 6 (75%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
