SUMITOMO RIKO Company Limited has 26 pending office actions in Transportation, E-Commerce & Mechanical Systems. The matters involve 25 examiners across 18 art units, showing broad examiner dispersion and substantial movement across technical groups. A portfolio-level review can help preserve consistency, but prosecution decisions will often need to remain application-specific because the examiner assignments are widely distributed.
IRVIN, THOMAS W is the busiest examiner, with 2 pending matters. That limited concentration does not outweigh the broader dispersion, so counsel should use examiner intelligence selectively while maintaining art-unit and technology-based coordination across the docket.
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 | 9 (39%) |
| §102 only | 3 (13%) |
| §112 only | 1 (4%) |
| Multi-statute (no §101) | 10 (43%) |
