Tech Center 2800 • Art Units: 2154 2818 2827 2893

This examiner grants 93% of resolved cases

Analysis

Huan Hoang has a high volume of 1231 resolved cases in Tech Center 2800 and Art Unit 2154. The allowance rate is 93.3%. This 93.3% rate is exceptionally high, suggesting a very favorable environment for patent grants. The 1231 resolved cases provide a massive data set that underscores a consistent and efficient examination style in Tech Center 2800.

The interview lift of 5.6% is low, likely because the baseline allowance rate of 93.3% is already very high. This 5.6% lift indicates that while interviews are available, they are not the primary driver of success. For the 1231 cases resolved, the 93.3% allowance rate remains the most significant metric. Practitioners should focus on maintaining the high quality of their initial filings to leverage this 93.3% rate.

The median days to allowance is 620. This 620-day timeline is notably short, indicating a very rapid pace of resolution. Applicants in Art Unit 2154 can expect a faster path to grant compared to other units. The combination of a 93.3% allowance rate and a 620-day median pendency makes this one of the most efficient dockets for the 1231 cases handled.
