// READING THIS EXAMINER

What the data says.

Examiner Hung T Havan maintains a public record across 3 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 125 disposed applications, the examiner allowed 58 and abandoned 67, yielding an allowance rate of 46%. Across the examiner's art units, allowance rates range from 18% to 64%, reflecting variation in the distribution of dispositions within each unit's record. This pooled figure describes past outcomes across all three art units combined and does not characterize any individual art unit's record.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled examiner record aggregates outcomes across multiple art units into a single allowance rate. The 46% figure represents allowed applications as a percentage of all decided applications (allowed plus abandoned), excluding pending cases. This aggregate describes the examiner's historical record across all assigned units and is not a forecast for any individual application. Variation across art units (18% to 64%) is normal and reflects differences in each unit's application mix and disposal patterns.

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 →

// BY ART UNIT

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Hung T Havan 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: 125 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.
