// READING THIS EXAMINER

What the data says.

Nathan Sadler maintains a 74% allowance rate across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). His record spans 2 art units. The allowance rate reflects the share of applications that were allowed among all decided (allowed and abandoned) applications in his pooled record. Allowance rates across his art units range from 54% to 81%, indicating variation in outcomes by art-unit subject matter. This pooled figure aggregates those separate records and describes past examination outcomes only, not any individual application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates examination outcomes across multiple art units within TC 2100. The 74% allowance rate is a historical snapshot of decided applications and does not predict the outcome of any particular case. Because different art units cover different subject matter, allowance rates can differ meaningfully between them. A pooled figure masks that variation; individual art-unit records are examined separately on this site to provide more granular context.

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 Nathan Sadler 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: 808 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.

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.
