Examiner Han V Doan has allowed 190 of 226 decided applications (84%) in Computer Architecture, Software, and Information Security.
Examiner Han V Doan maintains a public record across 3 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 226 disposed applications, the examiner issued allowances in 190 cases, for an overall allowance rate of 84%. Across the examiner's art units, allowance rates range from 82% to 100%. The record spans art units 2136, 2137, and 2186. A total of 36 applications were abandoned. This pooled figure aggregates outcomes across multiple art units and describes historical dispositions only.
This profile reports the examiner's pooled allowance rate—a historical aggregate across multiple art units in TC 2100. The 84% figure describes past decided cases and is not a prediction of any specific application's outcome. Allowance rates vary across art units (82% to 100%), reflecting differences in subject matter and prosecution patterns within the technology center. Pooled statistics describe the record as a whole and do not forecast results in any individual 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 97 decided applications with an interview and 80 without.
Primarily examines input/output (I/O) data transfer, and memory access and allocation.
Primarily examines computer-aided design (CAD).
Based on 13 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Methodology. This page pools every art unit in which Examiner Han V Doan 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: 246 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.
