Sungrow Power Supply Co., Ltd. has 25 pending office actions in Semiconductors, Circuits & Optics. The docket covers 24 distinct examiners and 15 art units, indicating broad examiner distribution and repeated matters within the art-unit structure. The examiner count is close to the pending-action count, while the smaller art-unit count supports art-unit-based docket management.
ZHANG, JUE is the busiest examiner, with 2 pending matters. That repeated assignment provides a defined opportunity to compare examination treatment, but it does not represent the broader portfolio. Counsel should coordinate semiconductor and circuit claim themes across the docket while tracking each art unit and examiner separately.
Based on the USPTO statutory response window for each pending office action. 7 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. 7 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 | 7 (28%) |
| §102 only | 3 (12%) |
| Multi-statute (no §101) | 15 (60%) |
How the docket's pending cases split across USPTO tech-center bands.
