Analysis

Dennis William Ruhl is positioned in Art Unit 3621 of Tech Center 3600. The examiner has a low allowance rate of 26.3% across 581 resolved cases. Despite the low overall rate, the interview lift of 23.5% shows that interviews can be a productive strategy for advancing an application. The median duration to achieve an allowance is 1724 days, which is a significant timeline for practitioners to consider.

The 26.3% allowance rate indicates a rigorous examination environment where the majority of cases do not result in a grant. However, the 23.5% interview lift suggests that direct engagement can nearly double the chances of success compared to the baseline. Given the 1724-day median to allowance, early intervention through interviews may be necessary to navigate the challenges presented by this examiner. The 581 resolved cases provide a high degree of statistical confidence in these trends.
