Examiner: MONTANARI, DAVID A

Tech Center 1600 • Art Units: 1632 1677

This examiner grants 65% of resolved cases

Analysis

David A. Montanari examines cases in Tech Center 1600 and Art Unit 1632, with a total of 771 resolved cases. His 64.7% allowance rate is the baseline for success, while the median days to allowance is 1399. This suggests that while a majority of cases eventually reach allowance, the process often requires a significant time commitment.

The most striking data point is the 49.0% interview lift. This is a high figure, indicating that interviews are associated with a much higher likelihood of allowance than the 64.7% baseline. For the 771 resolved cases, the interview has proven to be a transformative tool. Practitioners should prioritize interviews to navigate the 1399-day median pendency, as the 49.0% lift suggests that direct dialogue is an effective way to resolve the examiner's concerns.
