DOOSAN ENERBILITY CO., LTD. has 16 pending office actions in Medical Devices & Mechanical Engineering. The matters involve 15 distinct examiners across 14 distinct art units, indicating broad dispersion and limited repetition in both examination personnel and technical classifications. A matter-level workflow with technical grouping should fit the available portfolio structure.
PRUITT, JUSTIN A is the busiest examiner, with 2 pending matters. That small cluster permits targeted comparison of prosecution treatment, but it does not represent the overall docket. Counsel should maintain examiner-specific preparation while monitoring the separate art-unit assignments.
Based on the USPTO statutory response window for each pending office action. 5 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. 5 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 (6%) |
| §103 only | 9 (53%) |
| §112 only | 1 (6%) |
| Multi-statute (no §101) | 6 (35%) |
