What the data says.reading this examiner

Examiner Khanh Q Dinh maintains a pooled allowance rate of 88% across more than a thousand decided applications in Technology Center 2400. The examiner's public record spans 2 art units. Allowance rates across these art units range from 78% to 91%. The allowance rate reflects the percentage of applications decided—either allowed or abandoned—and does not include pending applications. This pooled figure aggregates the examiner's work across multiple art units and describes the historical record without predicting outcomes in any specific case.

How to read these numbers.

This pooled record combines the examiner's decided applications across 2 art units. Aggregate figures describe past decisions and do not forecast the result of any individual application. Different art units may have different allowance rates, reflected in the stated range. The pooled rate is a summary statistic and does not account for variation in application complexity, claim scope, prior art, or other case-specific factors that affect prosecution outcomes.

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 Khanh Q Dinh 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: 1,062 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.
