Analysis

NGUYEN, LUCAS QUOC is assigned to tech center 2800 and art unit 1786. The profile contains 2 resolved cases, both reflected in a 100.0% allowance rate. The interview lift is 0.0%, so the available record does not show an interview-related change in allowance outcomes. The median time to allowance is 1391 days, which is a significant timing signal despite the small sample.

The listed companies are Samsung Display Co., Ltd., LT Materials Co., Ltd., and LG Display Co., Ltd. The leading firms are Womble Bond Dickinson US LLP, CANTOR COLBURN LLP, and Duane Morris LLP (UDC). Practitioners should treat the outcome as preliminary because the resolved-case record is very small. The timing figure may inform planning, but neither it nor the allowance result should be generalized broadly.
