// READING THIS EXAMINER

What the data says.

Examiner Tuan S Nguyen has a pooled allowance rate of 77% across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). His record spans four art units within TC 2100. The allowance rate across these art units ranges from 56% to 93%, reflecting variation in the composition and outcomes of applications examined across different subject areas within the technology center. This pooled figure represents applications that have been decided—either allowed or abandoned—and excludes pending cases.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates allowance rates across multiple art units, producing a single overall percentage that reflects the examiner's historical outcomes across different areas of TC 2100. This aggregate figure describes past decisions and does not function as a prediction for any individual application. The range of allowance rates among art units shows where outcomes have varied; individual application outcomes depend on claim substance, prior art, and examination history.

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 →

// BY ART UNIT

The record, art unit by art unit.

Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Tuan S Nguyen has a public record within Technology Center 2100. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 14, 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: 539 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.
