Examiner: LE, HUNG D

Tech Center 2100 • Art Units: 2161 2171

This examiner grants 90% of resolved cases

Analysis

Hung D. Le maintains an allowance rate of 90.1 percent across 1099 resolved cases. Working in Tech Center 2100 and Art Unit 2161, the examiner's data shows that the vast majority of applications result in a grant. This 90.1 percent rate suggests a very favorable environment for applicants and indicates that the examiner is effective at identifying allowable subject matter. The history of 1099 cases offers a clear view of these trends.

The interview lift of 6.4 percent is relatively low, suggesting that the 90.1 percent allowance rate is achieved primarily through standard examination procedures and that the examiner is often persuaded by written arguments alone. The median days to allowance is 861, which is a reasonable and efficient timeframe for reaching a grant. Practitioners can expect a predictable and successful path to allowance with this examiner, as the data suggests a consistent approach. This makes the 861-day median pendency a reliable benchmark for applicants who prioritize a high probability of success and a steady pace of prosecution.
