What the data says.

David Yiuk Jung maintains a public record across 2 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 263 disposed applications, the examiner allowed 219 and abandoned 44, yielding an 83% allowance rate. This rate reflects the proportion of decided applications that were allowed relative to the total decided, and does not include pending cases. The pooled figure aggregates the examiner's work across both art units and describes the historical record without bearing on any individual application's outcome.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled, cross-art-unit record aggregates statistics across multiple art units. The allowance rate shown here is the proportion of allowed decisions among all decided applications across those units combined. Aggregate historical figures describe the examiner's past record and are not predictions specific to any single application. Understanding the breadth of art units and the overall decided volume provides context for evaluating an examiner's body of work.

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 →

METHODOLOGY & DISCLOSURES

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 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: 263 applications.
