Analysis

WHITROCK, ZACHARIAH KIRBY is assigned to Tech Center 4100 and Art Unit 3783. The record contains 4 resolved cases, all reflected in a 100.0% allowance rate. The median is 1106 days to allowance, and the interview lift is 0.0%, so the available data shows no measurable interview effect.

The listed companies are Becton, Dickinson and Company, Shl Medical AG, and Boston Scientific Corporation. The listed firms are Knobbe, Martens, Olson & Bear, LLP, MCDONNELL BOEHNEN HULBERT & BERGHOFF LLP, and Maschoff Brennan (OC)(BD). The very limited case volume makes broad conclusions inappropriate. Practitioners should treat the allowance result as preliminary and rely on application-specific analysis rather than assuming that interviews or prior outcomes will predict disposition.
