What the data says.reading this examiner

Anh Nguyen maintains a public record across four art units within Technology Center 2400, with an overall allowance rate of 81% among decided applications. This rate reflects outcomes across hundreds of decided applications pooled from art units 2442, 2454, 2456, and 2458. The allowance rate varies across these art units, ranging from 65% to 94%. The overall 81% allowance rate represents a factual summary of past dispositions and is not a prediction for any specific application.

How to read these numbers.

This record aggregates decisions from multiple art units within TC 2400, yielding a single pooled allowance rate. The aggregate figure describes historical outcomes across a substantial caseload and does not forecast results in any individual case. Variation across art units (65% to 94%) reflects differences in subject matter, application complexity, or examiner decisions specific to each unit's record.

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 Anh 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: 473 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.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
