Tianjin Sanan Optoelectronics Co., Ltd. has 11 pending office actions in the Semiconductors, Circuits & Optics technology area. These 11 actions are distributed among 11 distinct examiners, meaning every pending matter is currently before a different individual. The portfolio is active across 6 distinct art units. THIEN T MAI is the busiest examiner for the company, holding 1 pending office action.
With 11 distinct examiners for 11 pending actions, the prosecution workload is entirely decentralized. The 6 distinct art units indicate that the company's semiconductor and optics technology is being reviewed by several different specialized examination teams. Managing 11 pending office actions across 11 distinct examiners requires a broad approach to prosecution, as each application is being reviewed by a different person. This lack of concentration means that no single examiner's feedback will necessarily predict the outcome of other pending matters in the portfolio.
Based on the USPTO statutory response window for each pending office action. 3 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
Every pending office action with a known statutory deadline, placed on a days-until-due axis. Dots left of Today are overdue; the further right, the more runway. Cases that share a deadline window stack vertically. 3 of the docket's apps have a known mailing date.
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 | 4 (36%) |
| Multi-statute (no §101) | 7 (64%) |
How the docket's pending cases split across USPTO tech-center bands.
