Analysis

Mordecai Mizani Leavitt is assigned to Art Unit 1623 within Tech Center 4100. The available data for this examiner is based on 6 resolved cases, which is a small but notable sample size. Every case in this set resulted in an allowance, leading to a 100.0 percent allowance rate. This perfect rate suggests an exceptionally favorable environment for applicants, although it is based on a limited number of outcomes. The interview lift is recorded at 0.0 percent, meaning that interviews did not change the outcome for the cases in this specific data set.

The median time to allowance for these cases is 1062 days. This 1062-day timeline provides a baseline for the expected duration of prosecution from filing to grant. While the 100.0 percent allowance rate is highly encouraging, practitioners should remain aware that the 6 resolved cases represent a small portion of the examiner's potential career output. The 0.0 percent interview lift suggests that the examiner may be inclined to allow cases based on the written record alone. In Tech Center 4100, this examiner's current metrics point toward a highly efficient and successful path for patent applications, provided the 1062-day median pendency aligns with the applicant's goals.
