Ningde Amperex Technology Limited has 156 pending office actions in Chemistry & Materials. The docket spans 113 distinct examiners and 31 distinct art units, making it a large, distributed prosecution operation with substantial variation in examination assignments.
APPLEGATE, SARAH ARIMINTIA is the busiest examiner, with 4 pending matters. That workload is a focal point, but it represents only part of a much broader examiner network. Counsel should use structured docket controls, preserve art-unit-specific claim and prior-art analyses, and identify recurring issues without assuming that one examiner's treatment governs the full portfolio.
Based on the USPTO statutory response window for each pending office action. 22 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. 22 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 | 74 (48%) |
| §102 only | 2 (1%) |
| §112 only | 3 (2%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 3 (2%) |
| Multi-statute (no §101) | 70 (45%) |
| No statute on record | 1 (1%) |
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.
