Analysis

Brian A. Zimmerman operates within Tech Center 3700 and is assigned to Art Unit 2635. The examiner has a total of 33 resolved cases, which provides insight into his prosecution style. The current allowance rate stands at 18.2%, suggesting that obtaining a grant in this art unit can be challenging. Applicants should be prepared for a rigorous examination process given this rate across the 33 resolved cases.

The median days to allowance for successful applications is 934. This indicates the typical duration for the process to reach a conclusion.
