Analysis

HUYNH, LUAT T works in tech center 3600 and art unit 3661. The profile covers 614 resolved cases, with a 92.8% allowance rate and a median of 838 days to allowance. The 8.9% interview lift is positive, but it is smaller than the allowance-rate signal, suggesting that the overall prosecution record is already strongly favorable without relying heavily on interviews.

Qualcomm Incorporated, Komatsu Ltd., and Sumitomo Electric Industries Ltd. appear among the leading companies. Brooks Kushman P.C., Sheppard Mullin Richter & Hampton LLP, and Troutman Pepper Locke LLP are the listed firms. Applicants may therefore place particular emphasis on preserving claim scope during amendment practice, while still using interviews to clarify issues when they arise.
