// READING THIS EXAMINER

What the data says.

Bernard E Cothran holds a public record of 434 total applications across four art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Of 390 disposed applications, 181 were allowed, yielding an overall allowance rate of 46%. The examiner's record spans multiple art units (2123, 2128, 2147, 2188), and allowance rates across these units range from 27% to 65%. This pooled figure reflects decided cases only and aggregates outcomes across different subject areas within TC 2100.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This record presents pooled data across multiple art units, meaning the 46% allowance rate is an aggregate across different areas of TC 2100, not a single-unit statistic. Allowance rates vary by art unit (27% to 65% range), so a specific application's record depends on which unit examines it. These figures describe past outcomes and are not predictions about any individual application.

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 Bernard E Cothran 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: 434 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.
