Analysis

Kevin K. Pyo is a highly active examiner in Tech Center 2800 and Art Unit 2871, with 883 resolved cases. His allowance rate of 87.0% is very high, suggesting that most applications he reviews will eventually be granted. Such a high success rate suggests that the examination process here is exceptionally conducive for those seeking patent protection.

The interview lift is 9.9%, which is lower than many other examiners. This lower lift is likely due to the high baseline allowance rate of 87.0%, as there is less room for improvement through an interview. However, the 9.9% lift still indicates that interviews can be a useful tactic for resolving the few cases that do not immediately move toward allowance among the 883 resolved cases.

The median days to allowance is 813, which is a specific duration for the cases handled by Pyo. This efficiency, combined with the 87.0% allowance rate, suggests a streamlined prosecution experience. Applicants can expect a shorter 813-day timeline and a high probability of success when working with this examiner.
