What the data says.

David Ton has a pooled allowance rate of 94% across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). His public record spans 3 art units. The allowance rate—the share of decided applications (allowed and abandoned combined, excluding pending applications)—represents his overall record across these art units. Allowance rates among his art units range from 91% to 97%. This pooled figure aggregates work across multiple art units and does not predict any individual application outcome.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates allowance rates across multiple art units, smoothing variations within each unit into a single overall figure. This aggregate describes historical disposition patterns and is not a prediction about any specific application. Individual art-unit rates may differ from the pooled rate. Pooled figures are useful for understanding an examiner's general record but do not forecast the outcome of any particular case.

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 David Ton 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: 990 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.
