Asahi Kasei Battery Separator Corporation has 6 pending office actions in Chemistry & Materials. Those matters involve 6 distinct examiners and 5 distinct art units, so the portfolio spans multiple examination assignments rather than a single recurring channel.
WALLS, CYNTHIA KYUNG SOO is the busiest examiner, with 1 pending matter. No examiner accounts for a larger share of the listed workload, which supports matter-specific review of claim scope, cited art, and response timing.
The difference between examiner and art-unit breadth indicates that at least some examination assignments share an art unit while remaining separated by examiner. A coordinated internal docket can preserve consistency across the portfolio without assuming that one response approach will fit every matter.
Based on the USPTO statutory response window for each pending office action. 4 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. 4 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 | 4 (67%) |
| Multi-statute (no §101) | 2 (33%) |
