Analysis

RAYAN, MIHIR K is assigned to tech center 2600 and art unit 2619. The record shows 609 resolved cases, an 84.9% allowance rate, and a median of 860 days to allowance. The interview lift is 10.6%, so the profile associates interviews with a modest improvement relative to the overall allowance result.

The principal companies are Samsung Display Co., Ltd., Apple Inc., and Robert Bosch GmbH. The listed firms are Womble Bond Dickinson US LLP, BIRCH STEWART KOLASCH & BIRCH, LLP, and COOLEY LLP. Practitioners can use the combination of substantial case volume and an 84.9% allowance rate to inform examiner-specific preparation, while the 860-day median remains relevant for filing and portfolio timelines. The limited interview lift suggests that interview practice should be tailored to the issues in each application rather than treated as the sole driver of outcome.
