Examiner Sunray Chang has allowed 231 of 401 decided applications (58%) in Computer Architecture, Software, and Information Security.
Sunray Chang maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 401 disposed applications, 231 were allowed and 170 were abandoned, yielding an allowance rate of 58%. This record spans a single art unit. The allowance rate reflects the share of decided applications—those allowed or abandoned—and does not include pending filings. The figure is pooled across all art units in which this examiner has issued decisions.
This pooled record aggregates decisions across all art units where the examiner has acted. The overall allowance rate and application counts describe the examiner's historical record and do not predict the outcome of any specific application. Pooled figures mask variation among individual art units; a separate section of this page presents per-art-unit detail. Aggregate statistics are correlational, not causal.

A correlation, not proof that interviews cause allowances. Based on 134 decided applications with an interview and 267 without.
Methodology. This page pools every art unit in which Examiner Sunray 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: 401 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.
