Analysis

Nghi V Nguyen operates in Art Unit 1641 of Tech Center 1600, where 494 cases have reached a resolution. The allowance rate for these matters is 53.6%, providing a clear picture of the probability of a grant. This 53.6% rate is a central feature of the examiner's historical data across his 494 resolved cases.

The median days to allowance is 1318, which serves as a benchmark for the time required to complete the prosecution process.
