TRAN, SARAH ASHLEY is assigned to Tech Center 3600 and Art Unit 3656. The record shows 127 resolved cases, a 69.3% allowance rate, and a 20.2% interview lift. The median time to allowance is 1310 days. The smaller resolved-case base provides a more limited record for broad generalization, but the allowance and interview figures identify both a meaningful approval outcome and a potentially useful role for examiner discussions.

Seiko Epson Corporation, Xingmai Innovation Technology (Suzhou) Co. Ltd., and Volvo Group are the leading companies. The listed firms are Baker Botts L.L.P., Clements Bernard Walker, and FOLEY & LARDNER LLP. Counsel should pair technically precise written responses with focused interviews when claim interpretation or the relevance of the cited art remains contested.
