Examiner Oanh Duong has allowed 85 of 121 decided applications in Computer Architecture, Software, and Information Security.
Examiner Oanh Duong maintains a public record across a single art unit in Technology Center 2100 (Computer Architecture, Software, and Information Security). The pooled allowance rate stands at 70% of decided applications across hundreds of decided applications. This figure represents the percentage of applications that issued as patents or were abandoned, compared to all applications that reached a final disposition. The record reflects the examiner's activity within TC 2100, which covers computer architecture, software, and information security subject matter.
A pooled record aggregates data across all art units where an examiner works. The allowance rate reflects historical decisions on applications that reached closure—both allowed and abandoned cases. This aggregate figure describes the past record and is not a prediction of outcomes on any individual application. Patent prosecution involves many variables beyond examiner statistics, including application-specific claims, prior art, and procedural history.
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 information retrieval and database structures.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 32 decided applications with an interview and 89 without.

Methodology. This page pools every art unit in which Examiner Oanh Duong 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 July 14, 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: 121 applications.
Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

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.
