Analysis

Examiner Kieu D Vu operates within Art Unit 2141 of Tech Center 2400. With 87 resolved cases, the examiner demonstrates an allowance rate of 39.1 percent. This rate indicates a challenging prosecution environment where a minority of the applications result in a grant. The 87 resolved cases establish a clear pattern of rigorous examination within this technical field.

The median days to allowance for applications that reach grant is 1468. This duration reflects the time investment required to overcome rejections in Art Unit 2141. However, the data highlights a significant strategic opportunity: the interview lift is 32.9 percent. This 32.9 percent lift suggests that direct interaction with the examiner is highly effective at moving cases toward allowance. Given the 39.1 percent base allowance rate, practitioners may find that the interview process is a critical tool for addressing the examiner's concerns and shortening the 1468 day median timeline.
