Analysis

Justin S. Lee examines applications in Tech Center 3600 and is part of Art Unit 2172. He has overseen 483 resolved cases, providing a reliable foundation for statistical analysis. His allowance rate is 74.5 percent, which is a favorable metric for those appearing before him. This 74.5 percent rate indicates that a large majority of resolved cases result in an allowance.

The interview lift for this examiner is 25.6 percent. This 25.6 percent increase in the likelihood of allowance following an interview is a strong incentive for practitioners to engage in oral advocacy. Given the 483 resolved cases, this lift is a consistent feature of his examination practice. Attorneys should view the interview as a primary tactic to secure a grant, potentially moving the probability well beyond the initial baseline.

The median days to allowance is 1130. This duration suggests a longer prosecution cycle compared to some other units, requiring patience from the applicant. The 1130-day figure represents the typical time required to navigate the process to a successful conclusion. With a high allowance rate, the eventual outcome is often positive, even if it takes over a thousand days to reach.
