Examiner Vincent Wen-Liang Chang has allowed 356 of 469 decided applications (76%) in Computer Architecture, Software, and Information Security.
Vincent Wen-Liang Chang maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning four art units: 2115, 2116, 2119, and 2127. Across 469 decided applications, his allowance rate is 76%, reflecting 356 allowed applications and 113 abandoned applications. His pooled allowance rate ranges from 60% to 83% across these art units, indicating variation in allowance rates depending on the specific art unit and record composition.
This pooled record aggregates data across four art units within TC 2100. The overall 76% allowance rate describes past outcomes on decided applications and is not a prediction of any specific application's outcome. Variation across individual art units (60% to 83%) reflects differences in examination patterns or case composition by art unit. Pooled figures are descriptive of historical record only.
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 →
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.
Primarily examines electric power networks, supply, and distribution.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 147 decided applications with an interview and 134 without.
Primarily examines control or regulating systems.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 27 decided applications with an interview and 101 without.
Primarily examines neural-network / biological-model computing, and machine learning.
Based on 31 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Primarily examines control or regulating systems, and electric power networks.

Methodology. This page pools every art unit in which Examiner Vincent Wen-Liang 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: 500 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.
