Tech Center 3600 • Art Units: 3644

This examiner grants 69% of resolved cases

Analysis

Trinh T Nguyen has overseen 1044 resolved cases in Art Unit 3644 of Tech Center 3600. The examiner's allowance rate is 69.0 percent, which provides a reliable baseline for predicting prosecution outcomes. These 1044 resolved cases represent a significant body of work, offering practitioners a high degree of confidence in the examiner's established grant patterns and decision-making process.

The median days to allowance is 901, serving as a benchmark for the expected time from filing to patent issuance. This 901-day figure is an essential metric for managing client expectations and planning the various stages of the prosecution process. It indicates that the examiner maintains a relatively efficient pace of work compared to other units with longer pendency.

The interview lift of 27.4 percent suggests that direct engagement is a very effective strategy for moving cases toward allowance. This 27.4 percent increase over the 69.0 percent allowance rate indicates that interviews can significantly improve the probability of a grant by allowing for real-time clarification. Practitioners should leverage the 901-day median pendency and this high interview lift to optimize their overall strategy.
