What the data says.reading this examiner

Alan S Chou maintains a public record in Technology Center 2400 spanning one art unit. Across hundreds of decided applications, the examiner's allowance rate stands at 77%. This figure represents the percentage of applications that were allowed among all decided applications (allowed and abandoned, with pending applications excluded from the calculation). The allowance rate is pooled across the examiner's art unit assignments and reflects the historical record of dispositions in closed applications.

How to read these numbers.

This profile aggregates the examiner's record across all assigned art units into a single pooled allowance rate. The aggregate figure describes past examination outcomes and is not a prediction of how any individual application will be examined or decided. Pooled statistics represent correlational data only; they do not establish causation or indicate how specific applications will be handled. Individual application outcomes depend on claim scope, prior art, and other case-specific factors.

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 Alan S Chou 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: 736 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.
