Analysis

Etsub D Berhanu is an examiner in Tech Center 3700 and Art Unit 3735, with 809 resolved cases contributing to these metrics. The allowance rate of 65.3 percent indicates a favorable environment for applicants, though it requires navigating a median days to allowance of 1302. This timeline suggests that while success is likely, the prosecution process is relatively lengthy compared to other units.

The interview lift of 24.8 percent is a significant factor for strategy development. This figure implies that applicants who engage in interviews are much more likely to secure an allowance compared to those who rely solely on written responses. Given the volume of 809 resolved cases, this lift represents a consistent trend that practitioners can leverage to accelerate or improve their prosecution outcomes. The data supports a proactive approach to communication to navigate the 1302 median days to allowance effectively.
