Analysis

Chi D. Nguy is assigned to Tech Center 2400 and Art Unit 2431. The data set consists of 511 resolved cases, offering a broad view of prosecution outcomes. The allowance rate is 75.3 percent, which serves as the primary probability of success for applications in this examiner's portfolio.

The median days to allowance is 1260. This duration represents the middle point of the time required for an application to reach a grant. Practitioners should account for this 1260-day period when advising clients on the expected length of the patent acquisition process. This timing metric is based on the 511 resolved cases that have reached a conclusion.

The interview lift is 15.8 percent. This metric quantifies the increase in the probability of allowance following an interview. Compared to the 75.3 percent allowance rate, the 15.8 percent lift indicates that direct engagement with the examiner can be a useful strategy. For matters in Art Unit 2431, the data shows that oral advocacy is associated with a higher likelihood of achieving a grant.
