Listed by the USPTO as NGUYEN, ANH TUAN TUONG
Tech Center 3700 • Art Units: 3731 3779 3795
This examiner grants 4% of resolved cases
Anh Tuan Tuong Nguyen, operating in Art Unit 3731 of Tech Center 3700, has resolved 72 cases. The examiner has a very low allowance rate of 4.2%, which presents a significant challenge for applicants. The median days to allowance is 1585, reflecting a very long prosecution cycle for those few cases that reach allowance.
Despite the low overall allowance rate, there is an interview lift of 13.3%. This suggests that while success is rare, an interview can improve the odds of overcoming a rejection. Sony Group Corporation and Pentax Of America Inc. are the top companies listed in the data as having navigated this difficult environment.
Firms like CHIP LAW GROUP and Kilpatrick Townsend & Stockton LLP are among those who have managed these proceedings. Given the 4.2% allowance rate and the 1585-day median pendency, practitioners must be prepared for a rigorous and lengthy process. The 13.3% interview lift offers a small but critical advantage that should be utilized in every possible instance.
