Analysis

Catherine C. Premraj operates within Tech Center 3700 and Art Unit 3794, where she has overseen 209 resolved cases. Her allowance rate of 56.5 percent provides a baseline for expectations when filing applications in her docket. This 56.5 percent rate indicates the proportion of cases that successfully reach a grant.

The data shows an interview lift of 48.6 percent. This metric suggests that applications are more likely to reach allowance after a formal interview.

While 1519 days is the median, the interview lift suggests that proactive communication might be a factor in navigating the examination process. The 209 resolved cases provide the sample size for these performance trends.
