Sharkninja Operating LLC has 48 pending office actions in Medical Devices & Mechanical Engineering. The docket spans 42 examiners and 19 art units, which indicates substantial dispersion across the examination process. Because the examiner footprint is broad, a single examiner-centered strategy would not address most of the pending work.
ZERPHEY, CHRISTOPHER R is the busiest examiner, with 2 pending actions. That limited concentration makes the examiner a useful coordination point, but the wider docket requires separate tracking of examiner correspondence and art-unit practice. Organizing matters by technical issue and response deadline should help maintain consistency across the portfolio.
Based on the USPTO statutory response window for each pending office action. 10 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. 10 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 | 13 (29%) |
| §102 only | 6 (13%) |
| §112 only | 1 (2%) |
| Double-patenting + other | 1 (2%) |
| Multi-statute (no §101) | 24 (53%) |
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.
