Analysis

Duc T. Duong is an examiner in Tech Center 2600, specifically Art Unit 2419. He has a record of 774 resolved cases. This extensive experience in computer-related technologies provides a reliable basis for analyzing his prosecution tendencies. His high volume of resolutions indicates a seasoned examiner who is well-versed in the specific challenges of Tech Center 2600 and Art Unit 2419.

The examiner maintains a very high allowance rate of 89.4 percent. This suggests a highly favorable environment for applicants. He also provides an interview lift of 2.2 percent. While this lift is modest, it still indicates that interviews provide a slight benefit.

The combination of an 89.4 percent allowance rate and a 1035-day median suggests a very productive and predictable path to grant.

The 2.2 percent interview lift can be used as a strategic option to maintain progress toward the 89.4 percent success rate.
