Analysis

Lauren Peng Farrar serves in Tech Center 3900 and Art Unit 3763, where she has overseen 790 resolved cases. Her allowance rate of 78.6% suggests a strong probability of success for applicants. However, the median days to allowance is 2201, indicating a very long prosecution period for reaching a final grant.

For those practicing in Art Unit 3763, this 15.5% lift is a valuable tool for overcoming potential rejections. The 790 resolved cases reflect a well-established history of examiner behavior.
