Analysis

Marianne Dibrino has a lower allowance rate of 42.8% across 635 resolved cases in Art Unit 1641 of Tech Center 1600. The median days to allowance is quite long at 1732, indicating a prolonged prosecution process. However, the interview lift of 42.2% is very high, suggesting that interviews are a critical tool for overcoming the examiner's initial resistance and reaching an allowance.

In Tech Center 1600, practitioners must be prepared for a lengthy prosecution, as evidenced by the 1732-day median. The 42.8% allowance rate suggests that success is not guaranteed, but the 42.2% interview lift offers a powerful way to significantly increase the chances of success compared to the baseline. Given the 635 resolved cases, the data strongly supports the use of interviews as a central part of the prosecution strategy. Applicants should be patient with the 1732-day timeline but proactive in scheduling interviews to leverage the substantial lift in Art Unit 1641.
