Analysis

Caleb Logan Esquino is an examiner in Tech Center 3600 and Art Unit 2677, with 30 resolved cases. The allowance rate stands at 56.7 percent, representing a moderate level of difficulty for applicants during the examination process. The median days to allowance for these cases is 1067, which is a standard duration for applications in this technical field.

The interview lift of 0.6 percent is negligible, suggesting that interviews have had very little impact on the outcome of the 30 resolved cases. This indicates that written arguments and formal responses may be just as effective as verbal ones when dealing with this examiner. Practitioners should focus on the 56.7 percent allowance rate and the 1067-day timeline when managing expectations for their applications. Given the 0.6 percent lift, the decision to interview should be based on the need for clarification rather than a statistical expectation of a higher allowance probability.
