// READING THIS EXAMINER

What the data says.

Of 791 disposed applications, 649 were allowed, yielding an allowance rate of 82%. The examiner's record spans art units 2138, 2186, and 2188.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record combines outcomes from multiple art units into a single aggregate figure. The overall allowance rate of 82% describes past dispositions across all three art units and is not a prediction of any specific application's outcome. Variation across art units—reflected in the 72% to 86% range—shows that allowance rates differ by art unit. Aggregate statistics do not predict individual case results.

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 Michael C Krofcheck 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: 820 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.
