Examiner Tian-Pong Chang has allowed 129 of 197 decided applications (65%) in Computer Architecture, Software, and Information Security.
Examiner Tian-Pong Chang maintains a public record across 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 197 disposed applications, the examiner allowed 129 and abandoned 68, yielding an allowance rate of 65%. This rate is computed from decided applications only and does not reflect pending filings. The record spans two distinct art units, pooled here to show the examiner's combined output across the technology center.
A pooled record aggregates an examiner's decisions across multiple art units into a single allowance rate. The 65% figure describes historical dispositions and is not a prediction of any specific application's outcome. Aggregate statistics reflect past decisions on diverse subject matter within the technology center. Individual art-unit records, where available separately, may show different rates. Pooled data is useful context for understanding an examiner's overall record but does not determine any single case.
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 input/output (I/O) data transfer.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 83 decided applications with an interview and 99 without.
Primarily examines computer-aided design (CAD).
Based on 15 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Methodology. This page pools every art unit in which Examiner Tian-Pong 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: 197 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.
