This examiner grants 100% of resolved cases

Analysis

Rachel Yen Vi Dang is an examiner in Tech Center 2600 and Art Unit 2661. The current data includes 2 resolved cases, both of which were allowed, resulting in a 100.0 percent allowance rate. The median time to reach these allowances was 823 days. These figures provide an initial look at the examiner's performance, though the 2 cases mean the data may change as more resolutions occur. Applicants should view the 100.0 percent rate as a preliminary indicator of success in this unit.

The interview lift is 0.0 percent, indicating that the interviews conducted, if any, did not result in a higher allowance rate than the baseline for this sample. Practitioners should expect a median pendency of 823 days based on this limited history. While the 100.0 percent allowance rate is a positive sign, the 0.0 percent lift suggests that interviews have not yet been shown to statistically improve outcomes in this unit. As the examiner resolves more cases, these metrics will likely provide a more comprehensive view of the benefits of direct engagement and the stability of the 823-day median pendency.
