Examiner David Yiuk Jung has allowed 219 of 263 decided applications in Computer Architecture, Software, and Information Security.
David Yiuk Jung holds a public record across 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across hundreds of decided applications, the examiner's allowance rate is 83%, meaning that of all applications in the examiner's decided pool (allowed and abandoned combined), 83% were allowed. This rate reflects the examiner's historical disposition across the pooled record and does not constitute a prediction of any specific application's outcome.
This profile aggregates the examiner's record across multiple art units within TC 2100. The pooled allowance rate represents a historical summary of decided applications and is descriptive of past decisions only. Individual applications vary by claims, prior art, and arguments. The aggregate figure does not predict outcomes in any particular case or indicate how any future application will be examined.
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 network security, and computer and data security.

Methodology. This page pools every art unit in which Examiner David Yiuk Jung 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: 263 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.
