54 pending office actions • 8 art units • 26 examiners • 0 of 54 (0%) have an AI response strategy ready • 107 patents granted in the last 365 days
KARSTEN MANUFACTURING Corporation manages a large portfolio of 55 pending office actions in the Medical Devices & Mechanical Engineering technology area. These actions are distributed among 27 distinct examiners and 8 distinct art units. This indicates a significant concentration of matters within a relatively small number of administrative groups compared to the total volume of cases.
The busiest examiner, PIERCE, WILLIAM M, is currently handling 10 pending office actions, which is a substantial portion of the total 55. This concentration suggests that PIERCE, WILLIAM M has a significant influence on the overall prosecution timeline for the company. With 27 distinct examiners involved, many examiners are likely handling multiple cases, allowing for some consistency in prosecution across the portfolio.
The use of only 8 distinct art units for 55 pending office actions further reinforces the idea that the company's innovations are concentrated in specific technical niches within Medical Devices & Mechanical Engineering. Practitioners can leverage this concentration by identifying patterns in how these 8 distinct art units and 27 distinct examiners respond to similar arguments. The high volume of 55 pending office actions requires a robust management system to track the various deadlines and examiner interactions.
Based on the USPTO statutory response window for each pending office action. 11 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. 11 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.
