What the data says.

Hung H Dang holds a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning 70 disposed applications across 2 art units. Of those 70 decided applications, 44 were allowed and 26 were abandoned, yielding an allowance rate of 63%. This pooled figure represents the examiner's aggregate record across all assigned art units and reflects outcomes on applications that have reached final disposition. The record does not include pending applications.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates the examiner's performance across multiple art units within TC 2100. Aggregate allowance rates describe the historical distribution of allowed and abandoned applications—they are factual summaries of past decisions, not predictions about any specific pending application. Individual art units may have different allowance rates; pooled figures smooth those differences and are useful for understanding overall patterns, not for forecasting individual case 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 Hung H Dang 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 June 25, 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: 70 applications.

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.
