Beijing Shiyan Technology Co. Ltd. currently has 4 pending office actions within the Semiconductors, Circuits & Optics technology area. These 4 actions are distributed among 4 distinct examiners, indicating that each pending matter is being reviewed by a different individual. The portfolio spans 3 distinct art units, suggesting some technical overlap between the cases. CHARLES S CHANG is the busiest examiner, though he is responsible for only 1 pending office action.
The distribution across 4 distinct examiners means that no 1 examiner has a dominant influence over the portfolio. With 3 distinct art units involved, the company must manage its prosecution strategy across several different technical groups. This variety requires the legal team to adapt to different examiner styles within the Semiconductors, Circuits & Optics field. The fact that CHARLES S CHANG has 1 pending action shows that the workload is evenly spread. Practitioners should consider that the pending office actions are not concentrated under 1 examiner, which may lead to diverse outcomes.
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 |
|---|---|
| §101 only | 1 (25%) |
| §103 only | 1 (25%) |
| Multi-statute (no §101) | 2 (50%) |
