Examiner: MA, LISA

Tech Center 3600 • Art Units: 3628

This examiner grants 48% of resolved cases

Analysis

Lisa Ma, an examiner in Tech Center 3600 and Art Unit 3628, has a record of 174 resolved cases. The data shows an allowance rate of 47.7 percent, which indicates an environment where nearly half of the applications result in a grant. This probability of success is coupled with a median days to allowance of 1139, suggesting that the prosecution process typically spans this duration. Practitioners should prepare for an examination that requires sustained effort to reach a favorable conclusion based on these metrics.

The interview lift of 44.8 percent is a standout metric for this examiner. This lift is nearly equal to the baseline allowance rate of 47.7 percent, suggesting that an interview can nearly double the chances of securing an allowance. For cases that face initial rejections, the lift indicates that verbal advocacy is a primary driver of positive outcomes. Given the 1139-day median pendency, practitioners should consider scheduling interviews early in the process to address rejections and potentially reduce the time spent in prosecution within Art Unit 3628.
