K&N Engineering Inc. has 16 pending office actions in Chemistry & Materials. The portfolio spans 12 distinct examiners and 8 distinct art units, showing broad distribution across examination groups and substantial examiner coverage. Several matters therefore share examiner or art-unit relationships, creating opportunities to identify recurring claim and prior-art issues.
CLEMENTE, ROBERT ARTHUR is the busiest examiner, with 3 pending matters. This is the largest identified examiner-specific assignment, while the remaining work is distributed across other examiners and art units. Counsel should prioritize a unified technical record and cross-matter issue mapping, then tailor responses to the distinct examination relationships.
Based on the USPTO statutory response window for each pending office action. 6 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. 6 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 (25%) |
| Double-patenting + other | 1 (6%) |
| Multi-statute (no §101) | 11 (69%) |
