Analysis

Eva Y Montalvo is an examiner in Tech Center 2800 and Art Unit 2800, with a history of 314 resolved cases. Her allowance rate stands at 77.4 percent, which points toward a grant for a majority of the applications she reviews. The median days to allowance is 1105, reflecting the typical duration applicants can expect when navigating the prosecution process. The 314 resolved cases provide a robust sample size for understanding these trends and the general pace of examination within Tech Center 2800.
