Analysis

Duy M. Dang is an examiner in Tech Center 3600, assigned to Art Unit 2486. He has a high volume of 877 resolved cases and maintains a very high allowance rate of 91.0%. This figure suggests a very favorable environment for patent applicants. The interview lift is a modest 6.5%, which is likely due to the fact that the allowance rate is already exceptionally high without additional intervention.

The efficiency of prosecution is reflected in the median of 952 days to allowance. This timeline is relatively fast for Tech Center 3600, allowing for a resolution in under three years. For practitioners, the 877 resolved cases provide a reliable statistical foundation. The 91.0% allowance rate and the 952-day median pendency indicate that applications move quickly and successfully through Art Unit 2486. The 6.5% interview lift suggests that while interviews are helpful, they are not always necessary to achieve a grant.
