// READING THIS EXAMINER

What the data says.

Examiner Evan S Aspinwall has disposed of 720 applications across 4 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Of those decided applications, 603 were allowed, yielding an overall allowance rate of 84%. The allowance rate across the examiner's art units ranges from 78% to 99%, reflecting variation in the record as the examiner works across different art-unit assignments within TC 2100. The pooled figure aggregates these separate units into a single historical snapshot.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines results from multiple art units into one aggregate profile. The overall allowance rate—here 84% over 720 decided applications—describes historical output across all units combined and is not a forecast of any future application. The range (78% to 99%) shows that allowance rates differ among the individual art units; this variation is normal and reflects differences in art-unit composition and subject matter. Pooled data is useful for understanding overall examiner patterns but does not predict outcomes in any specific case.

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 Evan S Aspinwall 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: 743 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.
