Analysis

Louis J Rufo manages prosecution in Art Unit 1759 within Tech Center 1700. Across 720 resolved cases, the examiner has an allowance rate of 54.4%. Practitioners should note the significant interview lift of 22.9%, which indicates that direct communication with the examiner may substantially improve the probability of a grant. The median days to allowance stands at 1223, reflecting the typical duration for cases that reach a successful conclusion.

The data suggests that while over half of the applications are eventually allowed, the process requires a significant time investment. The 22.9% interview lift provides a clear tactical path for attorneys facing initial rejections. By engaging the examiner directly, applicants can bridge the gap between the baseline allowance rate and a successful outcome, potentially navigating the 1223-day median pendency more effectively. With 720 cases resolved, these statistics represent a well-established pattern for this examiner.
