Analysis

DANG, RACHEL YEN VI is a Tech Center 2600 examiner in Art Unit 2661 with 2 resolved cases. The allowance rate is 100.0%, and the median time to allowance is 823 days. Because the resolved-case volume is very limited, these figures should be treated as an early signal rather than a settled prosecution pattern.

The interview lift is 0.0%, so the available data does not show an interview-related change in allowance outcomes. Practitioners should review the individual prosecution record closely before drawing broader conclusions.
