Tech Center 3700 • Art Units: 3782 3785

This examiner grants 67% of resolved cases

Analysis

Brian Thai-Binh Khong, based in Tech Center 3700 and Art Unit 3782, has resolved 298 cases with an allowance rate of 67.1 percent. The median days to allowance is 1120. These metrics suggest a moderate probability of success within a standard timeframe for the technology center, with about two-thirds of cases reaching a grant.

The interview lift is 36.9 percent, which is a significant increase over the 67.1 percent baseline allowance rate. This suggests that Khong is very responsive to the interview process and that verbal engagement is highly effective. Practitioners should prioritize scheduling interviews to clarify technical points or claim interpretations, as the data shows a high correlation between verbal engagement and successful outcomes.

For applicants, the 1120 median days to allowance provides a predictable timeframe. The 36.9 percent interview lift is a key strategic tool that should be utilized early in the process. By engaging with Khong directly, practitioners can significantly enhance their chances of success and potentially resolve complex technical issues more efficiently than through written responses alone.
