// READING THIS EXAMINER

What the data says.

Examiner Hua Jasmine Song maintains a public record across 6 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 1,316 decided applications, the examiner's allowance rate stands at 94%. This figure represents 1,239 allowed applications against 77 abandoned applications. The examiner's work spans multiple art units, and allowance rates across these units range from 90% to 98%, reflecting variation in the examination record within this technology center.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates data across multiple art units, presenting an examiner's overall allowance rate as a historical summary. The 94% figure describes decided applications in the past and does not constitute a prediction about any specific application. Variation across art units (90% to 98%) reflects differences in examination activity and outcomes by subject area. Aggregate statistics are correlational observations, not causal indicators of how any individual 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 →

// BY ART UNIT

The record, art unit by art unit.

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.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Hua Jasmine Song 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: 1,349 applications.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
