This examiner grants 68% of resolved cases

Analysis

Tuongminh Nguyen Pham has overseen 506 resolved cases in Tech Center 3700 and Art Unit 3752. The allowance rate is 67.8 percent, which is a moderate rate that suggests a balanced examination style in the mechanical arts. This 67.8 percent rate indicates that approximately two out of three applications reach a successful conclusion. The 506 resolved cases provide a sufficient dataset for understanding the examiner's typical approach to prosecution. Practitioners should prepare for a balanced path that may involve multiple rounds of response.

The interview lift is 35.3 percent, which is one of the highest recorded for this group. This 35.3 percent figure strongly suggests that interviews are the most effective way to move a case toward allowance. The median days to allowance is 1042, indicating that applicants should expect a prosecution cycle that lasts for a significant period. Practitioners should prioritize scheduling interviews early in the process to overcome the 1042-day median wait time. The contrast between the 67.8 percent allowance rate and the 35.3 percent interview lift highlights the value of verbal advocacy.
