This examiner grants 88% of resolved cases
Ryan A. Lepisto is an examiner in Tech Center 4100 and Art Unit 2872. He has a high volume of 1183 resolved cases, which provides a very robust dataset for analysis. His allowance rate is 87.7 percent, indicating that a vast majority of applications in his docket reach issuance. This 87.7 percent rate suggests a favorable environment for applicants seeking patent protection. The median days to allowance is 681, indicating an efficient path through the patent office compared to many other examiners.
The interview lift is 7.8 percent, which is a modest increase in the probability of success. Because the baseline allowance rate is already 87.7 percent, most cases reach allowance regardless of whether an interview occurs. However, the 7.8 percent lift still offers a benefit for resolving remaining issues. Practitioners can expect a relatively fast resolution of 681 days on average when working with this examiner. The combination of a high allowance rate and a short timeline makes Art Unit 2872 under his review a productive venue for patent prosecution. Applicants should focus on clear written advocacy to maintain the momentum of the 681-day median timeline.
