24 pending office actions • 13 art units • 22 examiners • 0 of 24 (0%) have an AI response strategy ready • 237 patents granted in the last 365 days
Changxin Memory Technologies Inc. has 24 pending office actions in Semiconductors, Circuits & Optics. The matters involve 22 distinct examiners across 12 distinct art units, creating a broad and distributed prosecution workload. The difference between pending matters and examiner assignments indicates that at least some examiner responsibility is shared across matters.
SIPLING, KENNETH MARK is the busiest examiner, with 2 pending matters. That allocation is higher than the allocation shown for the other identified examiners, making this examiner a useful point for focused docket review.
The art-unit dispersion calls for portfolio-level tracking by technical unit as well as by examiner. Counsel can coordinate recurring claim or prior-art issues where assignments overlap, while preserving separate strategies for the many examination relationships.
Based on the USPTO statutory response window for each pending office action. 10 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. 10 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 | 13 (54%) |
| §102 only | 1 (4%) |
| §112 only | 3 (12%) |
| Multi-statute (no §101) | 7 (29%) |
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.
