Analysis

Daniel J Berns is an examiner in Tech Center 1700 and Art Unit 1734 with 826 resolved cases. He maintains an allowance rate of 73.0 percent and a median days to allowance of 977. These figures provide a baseline for what practitioners can expect during the prosecution of an application. The 826 resolved cases suggest that these metrics are based on a significant amount of historical data within the 1700 tech center.

The data shows an interview lift of 34.2 percent. This suggests that engaging in an interview can increase the probability of an allowance beyond the 73.0 percent baseline. With the resolved cases, the 34.2 percent lift is a relevant metric for strategic planning. Practitioners should consider the 977-day median when advising clients on the likely duration of their case. The contrast between the allowance rate and the lift indicates that direct communication is a factor in the outcomes for this examiner. Using this information to improve upon the 73.0 percent allowance rate is a strategy for any applicant.
