Tech Center 1600 • Art Units: 1634 1682

This examiner grants 20% of resolved cases

Analysis

Bradley L. Sisson in Art Unit 1634 has a high volume of 746 resolved cases. The allowance rate is 19.7 percent, which is quite low for Tech Center 1600. The interview lift is 20.5 percent. This data suggests that while the examiner is strict, an interview nearly doubles the chances of allowance relative to the baseline rate.

The median time to allowance is 1587 days. This long pendency, combined with the 19.7 percent allowance rate, indicates a difficult prosecution environment. Practitioners should consider the 20.5 percent interview lift as a critical component of their strategy to navigate the lengthy 1587-day timeline.
