// READING THIS EXAMINER

What the data says.

Evan S Aspinwall maintains a pooled allowance rate of 84% across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). His record spans four art units (2152, 2154, 2156, and 2162). The allowance rate ranges from 78% to 99% across these art units, reflecting variation in the decided-application population within each unit. This pooled figure represents the share of his decided applications (allowed and abandoned combined) that resulted in allowance, and does not account for pending cases.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled allowance rate aggregates results across multiple art units into a single figure. This rate describes the examiner's past record on decided applications and is not a prediction of any specific application's outcome. Because the record spans different art units with different allowance rates, the pooled figure masks variation by subject area. The range (78% to 99%) shows that individual art units differ materially, making the pool a summary measure rather than a guide to any particular 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 →

// 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 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 July 14, 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.

Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.
