9 pending office actions • 3 art units • 8 examiners • 0 of 9 (0%) have an AI response strategy ready • 13 patents granted in the last 365 days
Histosonics Inc. currently manages 9 pending office actions within the Medical Devices & Mechanical Engineering technology area. These matters are distributed across 8 distinct examiners and 3 distinct art units. This distribution indicates a spread of examination across the USPTO, with very little concentration among specific examiners.
TURCHEN, ROCHELLE DEANNA is identified as the busiest examiner for this portfolio, currently handling 2 pending office actions. This represents a small portion of the total 9 pending office actions. The presence of 3 distinct art units suggests that the company's medical device innovations are concentrated within a few specialized classifications within the patent office.
Practitioners should note that with 8 distinct examiners for 9 actions, almost every pending matter is being reviewed by a different individual. This limited examiner overlap means that prosecution strategies may need to be tailored to the specific preferences of many different officials. Managing 3 distinct art units requires a focused understanding of the examination guidelines within those specific divisions of the Medical Devices & Mechanical Engineering sector.
Based on the USPTO statutory response window for each pending office action. 2 of the docket's apps have a known mailing date; the rest are excluded from the tile counts.
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 | 5 (56%) |
| Multi-statute (no §101) | 4 (44%) |
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.
