What the data says.

Thomas Duong's public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spans one art unit. Across dozens of decided applications, his allowance rate is 56%. This figure represents the share of applications that were allowed among all decided applications (allowed and abandoned combined), excluding any pending matters. The allowance rate is based on the examiner's pooled record and describes his historical disposition of applications within this technology center.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates the examiner's work across all assigned art units and presents an overall allowance rate. Pooled figures describe past outcomes across multiple art units and are not predictions about the disposition of any specific application. An aggregate allowance rate reflects the examiner's historical record on decided applications but does not indicate how any individual application will be examined or resolved.

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

The record, art unit by art unit.

Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Thomas Duong 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: 71 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.
