What the data says.reading this examiner

An V Nguyen has a public record of 44% allowance rate across hundreds of decided applications pooled from 1 art unit in Technology Center 2400. The allowance rate reflects the percentage of applications that issued as patents among all decided applications (allowed and abandoned combined), excluding pending applications. This pooled figure aggregates the examiner's record across all art units within the technology center and represents historical disposition data only.

How to read these numbers.

This pooled record combines decided applications from multiple art units into a single aggregate allowance rate. The 44% figure describes the examiner's past record and is not a prediction about any specific application's outcome. Pooled statistics across art units reflect general patterns but do not indicate how any individual application will be examined or disposed of. The data serves as historical context only.

These are aggregate statistics from this examiner's past public record — not predictions about any specific application. The per-art-unit figures below show how the record varies across art units. Our approach to patent prosecution →

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner An V Nguyen has a public record within Technology Center 2400. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 22, 2026. The overall allowance rate is total allowed divided by total decided applications (allowed plus abandoned) across all art units — not an average of the per-art-unit rates; pending applications are excluded. Figures are rounded for display. Pooled sample: 201 applications.

Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes. Where this page compares an examiner's allowance rate to an art-unit average, that comparison is a factual description of the public record, not a characterization of any individual examiner's conduct or competence.
