Technology area: Chemistry & Materials
17 pending office actions • 9 art units • 17 examiners • 0 of 17 (0%) have an AI response strategy ready • 1 patents granted in the last 365 days
Jiangsu Zenergy Battery Technologies Co. Ltd. maintains a robust portfolio with 16 pending office actions in the Chemistry & Materials technology area. These actions are distributed across 8 distinct art units, indicating a broad technical footprint within the USPTO. The involvement of 16 distinct examiners means that every pending action is currently being reviewed by a different individual. This distribution across 8 art units reflects a decentralized prosecution strategy.
CHENG, VIVIAN S is identified as the busiest examiner for the company, currently managing 1 pending office action. This single action is part of the total pending workload, as 16 distinct examiners are handling the current matters. The fact that the busiest examiner only has 1 pending action highlights the high level of examiner diversity. Practitioners should note that while the portfolio is centered in Chemistry & Materials, it spans 8 distinct art units, requiring coordination across multiple specialized sub-units at the patent office.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 (24%) |
| §112 only | 2 (12%) |
| Multi-statute (no §101) | 11 (65%) |
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.
