// READING THIS EXAMINER

What the data says.

Phuong H Nguyen maintains a public record across 5 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across hundreds of decided applications pooled from all art units, the examiner's allowance rate is 68%. The allowance rate—the share of applications that were allowed among all decided (allowed and abandoned) applications—ranges from 56% to 92% across these art units. This range reflects variation in the examiner's record across the different art units within TC 2100. The overall 68% figure represents the aggregate of the examiner's decisions across all five art units combined.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This record aggregates applications across multiple art units within TC 2100, pooling all decided cases. The 68% allowance rate describes the examiner's past record across these combined art units and is not a prediction of any specific application's outcome. Because the data combines different art units with different subject matter concentrations, the aggregate rate may differ substantially from rates in any single art unit. Per-art-unit detail is available separately and may show significant variation from the pooled figure.

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 Phuong H 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: 369 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.
