Yamaguchi University has 5 pending office actions in Biotechnology & Pharmaceuticals. The matters involve 5 distinct examiners and 4 distinct art units, showing broad examiner distribution with some concentration among technical groups.
XU, JUSTIN is the listed busiest examiner, with 1 pending action. The lack of a larger examiner concentration favors separate prosecution planning for each matter. The 4-art-unit structure can still support technical grouping when reviewing recurring terminology, disclosure support, or prior-art issues.
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 + other | 1 (20%) |
| §103 only | 1 (20%) |
| §112 only | 2 (40%) |
| Multi-statute (no §101) | 1 (20%) |
