What the data says.

David J Pearson's public record spans one art unit in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 58 disposed applications, the examiner's allowance rate is 41%, meaning 24 applications were allowed and 34 were abandoned.

The allowance rate is calculated from disposed applications only, not from total filings.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates all art units under the examiner's jurisdiction and presents historical outcomes only. The 41% allowance rate describes past dispositions and does not constitute a prediction about any specific application's outcome. Aggregate figures mask variation across individual art units; applicants may review per-art-unit data separately to understand record detail by assigned subject-matter area.

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 →
