Analysis

ONDREJCAK, ANDREW DOMENIC works in tech center 3700 and art unit 3752. The record contains 24 resolved cases, with a 45.8% allowance rate and a median of 1184 days to allowance. Interview lift is 43.2%, indicating a positive association between interviews and allowance outcomes. The small case base makes the figures less stable, so practitioners should avoid treating them as a firm prediction for an individual application.

The principal companies are Tyco Fire Products L.P., Has LLC, and Huawei Technologies Co., Ltd. The listed firms are Foley & Lardner LLP, Belvis Law, and Barnes & Thornburg LLP (IN). The relatively low allowance rate supports early review of claim scope and prior-art distinctions. Interviews may provide useful access to the examiner's concerns, but the 1184-day median reinforces the need for written fallback positions and timely decisions on continued prosecution.
