Examiner Eric Chang has allowed 395 of 578 decided applications (68%) in Computer Architecture, Software, and Information Security.
Eric Chang's public record spans 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 578 disposed applications, 395 were allowed and 183 abandoned, yielding an allowance rate of 68%. The allowance rate varies across his art units, ranging from 64% to 81%. This pooled figure represents his overall record in TC 2100 and reflects the aggregate outcome of decided cases across both units.
A pooled record aggregates statistics across multiple art units, producing a single allowance rate that describes past outcomes without distinguishing between individual units. The overall figure—here, 68% over 578 decided applications—is a historical summary. The range (64% to 81%) shows variation among the art units but does not predict the outcome of any particular application. Aggregate rates are correlational data about past dispositions, not forecasts.
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. This page pools every art unit in which Examiner Eric Chang 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: 578 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.
