Ningde Amperex Technology Limited maintains a large portfolio with 152 pending office actions in the Chemistry & Materials technology area. These actions are distributed among 108 distinct examiners across 19 distinct art units, indicating a massive and highly diversified prosecution effort.
APPLEGATE, SARAH ARIMINTIA is the busiest examiner, currently handling 4 pending office actions. This represents a low concentration of work per examiner, as the vast majority of the 108 distinct examiners are likely managing a single action each. The spread across 19 distinct art units shows that the company's battery and material technologies are being scrutinized by a wide array of specialized units within the USPTO.
With 152 pending office actions, the company must manage a high volume of responses. The diversity of the portfolio suggests that their innovations span numerous chemical and material classifications, requiring a sophisticated legal strategy to navigate the various examination standards encountered.
Based on the USPTO statutory response window for each pending office action. 25 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. 25 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 | 4 (3%) |
| Double-patenting only | 1 (1%) |
| Double-patenting + other | 4 (3%) |
| Multi-statute (no §101) | 67 (44%) |
| 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.
