Analysis

Nikolay K Yushin has an extensive record of 1797 resolved cases in Art Unit 2800 of Technology Center 3600. The examiner maintains an allowance rate of 93.3 percent. The median days to allowance is 668, which is the timeline for this volume of cases. The interview lift of 2.1 percent is minimal, which is expected given that the 93.3 percent allowance rate leaves little room for increase.

Practitioners should focus on meeting the initial requirements of the art unit, as the 668-day timeline and grant rate suggest a path to allowance. With 1797 cases resolved, the examiner demonstrates a predictable approach to patent examination. The 2.1 percent lift indicates that interviews are seldom the deciding factor. The 93.3 percent allowance rate and 668-day median pendency are the metrics for this profile. This data provides a benchmark for efficiency in Technology Center 3600.
