Analysis

Jayanta Chatterjee examines applications in Tech Center 1700 and Art Unit 1662, with 22 resolved cases. The allowance rate is 45.5%, and the median days to allowance is 952. These figures provide a timeline and success rate for the expected duration of the prosecution process.

A key finding in this profile is the interview lift of 80.0%. This very high lift indicates that interviews are a powerful tool for overcoming rejections and securing an allowance with this examiner. For practitioners, this suggests that direct communication is likely the most effective way to advance a case. Although the 45.5% allowance rate is based on a sample of 22 resolved cases, the 80.0% lift is a strong signal that interviews can change the trajectory of an application. The 952 median days to allowance also helps in planning the overall timeline for prosecution.
