TCL Zhonghuan Renewable Energy Technology Co. Ltd. maintains a robust prosecution pipeline with 11 pending office actions in the Medical Devices & Mechanical Engineering technology area. These matters are distributed across 9 distinct examiners, which suggests a diverse range of perspectives and potential outcomes within the USPTO. The workload spans 4 distinct art units, indicating that the company's technical interests in this field are broad enough to trigger multiple specialized review groups.
The busiest examiner for this portfolio is QI, HUA, who is currently managing 3 busiest examiner pending actions. This concentration with a single examiner represents a significant portion of the 11 pending office actions, making the relationship with this examiner a priority for the company's legal strategy. With 9 distinct examiners in total, the company must manage various examination styles simultaneously. The distribution across 4 distinct art units further highlights the complexity of the portfolio's technical footprint. Successfully navigating these matters will require a multifaceted approach to satisfy the requirements of the various examiners involved.
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 |
|---|---|
| §101 + other | 1 (9%) |
| §103 only | 5 (45%) |
| Multi-statute (no §101) | 5 (45%) |
