What the data says.

Hexing Liu maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning 2 art units. Across 216 disposed applications, 142 were allowed and 74 were abandoned, yielding an allowance rate of 66%.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates data across multiple art units within TC 2100. The allowance rate and application counts describe the examiner's past record and do not constitute a prediction about any specific application. Pooled figures mask variation that may exist between individual art units. Applicants seeking detail about a particular art unit may reference separate per-art-unit data if available. All figures are historical and correlational only.

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 →

  • What do these figures mean for my application?
    These statistics describe the examiner's historical record and are not a prediction of any specific application's outcome. Actual results depend on claim scope, prior art, and prosecution conduct.

METHODOLOGY & DISCLOSURES

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: 216 applications.

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.
