NSK Ltd. has 5 pending office actions in Semiconductors, Circuits & Optics. The matters are assigned to 5 examiners and 3 art units, creating broad examiner distribution with some art-unit clustering.
JOHNSON, ERIC is the busiest examiner, with 1 pending matter. No examiner accounts for multiple listed actions, so prosecution management should emphasize consistent portfolio controls while tailoring substantive responses to each examination record and art-unit context.
Based on the USPTO statutory response window for each pending office action. 3 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. 3 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 (12%) |
| §101 + other | 2 (25%) |
| §103 only | 2 (25%) |
| Multi-statute (no §101) | 3 (38%) |
