Zhuhai Cosmx Battery Co., Ltd. has 41 pending office actions in Chemistry & Materials. The portfolio reaches 39 examiners and 18 art units, showing substantial examiner dispersion alongside repeated use of certain technical groups. The number of pending matters exceeds the number of examiners, so some assignments contain multiple matters, while the art-unit distribution is more concentrated.
CHMIELECKI, SCOTT J is the busiest identified examiner, with 2 pending matters. That limited concentration does not replace the need for portfolio-level coordination. Counsel should maintain consistent positions on battery-related claim scope and disclosure while separately monitoring art-unit practices and examiner-specific response opportunities.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 | 11 (30%) |
| §102 only | 3 (8%) |
| §112 only | 2 (5%) |
| Double-patenting + other | 2 (5%) |
| Multi-statute (no §101) | 19 (51%) |
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.
