Analysis

Drew Joseph Mitchum is an examiner in Tech Center 3700, working in Art Unit 1792. He has 2 resolved cases, which provides a very limited dataset for analysis. The allowance rate for these cases is 50.0 percent, reflecting the outcome of only 2 matters.

The record shows an interview lift of 0.0 percent. This figure indicates that for the 2 resolved cases, interviews did not result in an increased likelihood of allowance compared to the 50.0 percent baseline. Practitioners should be aware that this metric may change as more cases are resolved in Art Unit 1792.

The median days to allowance for this examiner is 1240. This duration is based on the small number of successful applications in his record. While the 2 resolved cases offer some insight, the 1240-day timeline and the 50.0 percent allowance rate should be viewed as preliminary figures.
