Analysis

Monica A. Mandel works in Tech Center 3600 and Art Unit 3621. She has 326 resolved cases with an allowance rate of 18.1 percent. This low rate indicates a difficult prosecution environment. The median days to allowance is 2090, representing an extended commitment for those who eventually secure a patent.
