Analysis

David R. Lazaro has an allowance rate of 87.1 percent across 774 resolved cases in Tech Center 2400. Operating in Art Unit 2155, the examiner's statistics point toward a high likelihood of success for applicants. This volume of 774 cases provides a stable foundation for assessing examination trends and preparing prosecution strategies that align with the examiner's historical preferences.

The interview lift of 3.7 percent suggests that interviews have a limited impact on the final outcome compared to the initial examination and written responses. Applicants may find that focusing on the quality of the written record is the most effective way to secure a grant. The median days to allowance is 1031, which defines the expected timeframe for reaching a successful conclusion. This combination of an 87.1 percent grant rate and a 1031-day timeline suggests a steady prosecution environment where persistence in written advocacy is likely to be rewarded with a patent.
