Analysis

NGUYEN, THUY-VI THI works in USPTO Technology Center 3600, art unit 3656. The record contains 792 resolved cases and an allowance rate of 51.9%. The median time to allowance is 1335 days. Interview lift is 11.3%, showing a positive but less pronounced association between interviews and allowance outcomes.

The principal companies are Intuitive Surgical Operations Inc., Toyota Motor Corporation, and NEC Corporation. The listed firms are EIP US LLP, Harrity & Harrity, LLP, and HAUPTMAN HAM, LLP. The allowance rate signals a demanding prosecution environment, making claim preparation and prior-art analysis particularly important. Interviews may still assist with clarification, but the recorded lift supports using them as one element of a broader strategy rather than a substitute for strong written advocacy. The median timing also favors early portfolio planning and careful coordination of prosecution with product development and filing priorities.
