This examiner grants 59% of resolved cases

Analysis

Brendan Thomas Tinsley manages cases in Art Unit 1634 of Tech Center 1600, with 46 resolved cases. The allowance rate is 58.7 percent, and the median days to allowance is 1427. These figures suggest a rigorous examination process with a significant time commitment required from applicants.

The most notable statistic is the interview lift of 73.9 percent. This is an extremely high value, indicating that interviews are the most effective way to secure a grant with this examiner. The disparity between the 58.7 percent baseline allowance rate and the 73.9 percent lift suggests that written prosecution alone may be insufficient. Practitioners should view an interview as a mandatory step in their strategy, as the 73.9 percent lift provides a massive statistical advantage during the 1427 day prosecution period.
