// READING THIS EXAMINER

What the data says.

Hiep T Nguyen's public record spans 5 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Across more than a thousand decided applications in this technology center, the allowance rate is 95%. The allowance rate ranges from 94% to 98% across these art units. This pooled figure represents the share of applications in the examiner's decided record that were allowed, rather than abandoned, during the period covered by the public record.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates allowance rates across multiple art units, smoothing variation among individual units into a single overall percentage. The 95% figure describes the examiner's past record across all decided applications in TC 2100 and is not a prediction of outcome for any specific application. Pooled data obscures art-unit-level detail; a separate section of this page shows per-unit rates for those seeking unit-specific 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

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Hiep T 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: 1,546 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.
