Rheem Manufacturing Company has 34 pending office actions in Medical Devices & Mechanical Engineering. The matters involve 31 distinct examiners and 13 distinct art units, combining substantial examiner dispersion with repeated activity across the art-unit structure.
ZERPHEY, CHRISTOPHER R is the busiest examiner, with 3 pending matters. That assignment is the clearest examiner-level concentration, while 31 examiners overall require a broad prosecution management system. Counsel can coordinate recurring technical issues through the 13 art units, but should preserve examiner-specific positions for the matters assigned outside that concentration.
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 |
|---|---|
| §101 + other | 1 (3%) |
| §103 only | 14 (41%) |
| §112 only | 3 (9%) |
| Multi-statute (no §101) | 16 (47%) |
How the docket's pending cases split across USPTO tech-center bands.
Manual office-action response work runs about 10 hours per case. The time-saved bands below show what IP Author's prosecution pipeline typically delivers — a conservative 20% on the low end, 35% in the middle, 50% on the high end.
