Analysis

AN, IG TAI works in tech center 4100 and art unit 3652. The profile covers 549 resolved cases, with a 57.4% allowance rate and a median of 1322 days to allowance. The interview lift is 24.7%, showing a positive association that may justify deliberate interview preparation. The allowance result is near the middle of the recorded outcomes, so interviews should be paired with careful claim analysis and written responses rather than treated as sufficient on their own.

NVIDIA Corporation, Samsung Electronics Co., Ltd., and Robert Bosch GmbH are the leading companies. The firms are Barnes & Thornburg LLP (IN), CANTOR COLBURN LLP, and Dickinson Wright PLLC - Washington DC. Practitioners should account for the extended median timeline when scheduling prosecution and may use interviews to clarify technical distinctions in complex matters.
