Analysis

Cao H. Nguyen is an examiner in Tech Center 2100 and Art Unit 2171. The data for this profile is based on 1152 resolved cases. The allowance rate is 90.9 percent, which serves as the baseline probability of success for applications in this portfolio. This rate provides a benchmark for practitioners to evaluate the likelihood of a grant when filing in this unit.

The median days to allowance is 932. This figure represents the time required for an application to reach a grant. Practitioners can use the 932-day timeline to manage client expectations regarding the duration of the prosecution process. This duration reflects the pace of work for the 1152 resolved cases concluded by the examiner.

The interview lift is 7.4 percent. This metric indicates the increase in the allowance rate when an interview is conducted. When compared to the 90.9 percent allowance rate, the 7.4 percent lift suggests that oral advocacy provides a modest benefit for resolving outstanding issues. For matters in Art Unit 2171, the data indicates that interviews are associated with a higher likelihood of moving a case toward allowance.
