// READING THIS EXAMINER

What the data says.

Examiner Nan Hutton maintains a pooled allowance rate of 71% across 246 disposed applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner works across 5 art units: 2152, 2154, 2155, 2163, and 2169. Allowance rates across these art units range from 53% to 91%, reflecting variation in the examiner's record by subject matter within TC 2100. This pooled figure represents the examiner's overall record and describes past dispositions only.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates an examiner's work across multiple art units into a single allowance rate. This aggregate describes the examiner's historical disposition of applications and does not predict the outcome of any specific filing. The range from minimum to maximum allowance rates shows variation across different art units; individual applications fall within the particular art unit's record, not necessarily the overall pool.

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 Nan Hutton 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: 246 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.
