Analysis

An Bach Phan has a limited history in Art Unit 1724 of Tech Center 3700, with 4 resolved cases. The allowance rate is 75.0 percent, though this figure is based on a very small sample size. This 75.0 percent rate suggests that three out of four applications in this initial dataset reached a successful conclusion. The 4 resolved cases provide a preliminary look at the examiner's prosecution style. Practitioners should monitor these metrics as the examiner's docket continues to grow over time.

The interview lift is 50.0 percent, suggesting that interviews may be highly beneficial for resolving rejections. This 50.0 percent lift indicates that direct communication with the examiner is associated with a higher probability of allowance in this small sample. The median days to allowance is 1055, which serves as the primary timing benchmark for successful prosecution. Practitioners should use this 1055-day figure to manage client expectations regarding the duration of the examination. The combination of a 75.0 percent allowance rate and a 50.0 percent interview lift provides an initial positive outlook for applicants.
