465 pending office actions • 84 art units • 263 examiners • 0 of 465 (0%) have an AI response strategy ready • 532 patents granted in the last 365 days
Contemporary Amperex Technology Co., Limited manages a portfolio in the Chemistry & Materials technology area with 473 pending office actions. These cases are distributed among 261 distinct examiners, indicating a range of individual perspectives at the patent office. The involvement of 49 distinct art units further demonstrates the technical breadth of the portfolio, as the 473 pending actions are spread across many specialized groups. WEINER, LAURA S is the busiest examiner, currently handling 8 pending office actions.
While WEINER, LAURA S has the highest individual workload, her 8 pending actions are a small part of the 473 total pending actions. The fact that 261 distinct examiners are involved means that the company must manage many unique examiner interactions. The 49 distinct art units suggest that the company's chemistry and battery innovations are being reviewed by a variety of technical experts. This distribution across the 261 examiners and 49 art units requires a robust prosecution strategy to maintain consistency across the 473 pending matters.
Based on the USPTO statutory response window for each pending office action. 91 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. 91 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 only | 1 (0%) |
| §101 + other | 15 (3%) |
| §103 only | 137 (29%) |
| §102 only | 20 (4%) |
| §112 only | 9 (2%) |
| Double-patenting only | 1 (0%) |
| Double-patenting + other | 16 (3%) |
| Multi-statute (no §101) | 266 (57%) |
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.
