What the data says.

Christopher N Do has a public record spanning 2 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 83 disposed applications, his allowance rate is 67%, meaning 56 applications were allowed and 27 abandoned. The allowance rate ranges from 54% to 73% across his art units, reflecting variation in outcomes between the different subject-matter areas in which he works. This pooled figure aggregates his record across all units and describes historical disposal outcomes without application to any pending matter.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates an examiner's work across multiple art units and reflects past dispositions. The overall allowance rate—here, 67% across 83 decided applications—is a historical summary and is not predictive of any individual application's outcome. The range (54% to 73%) shows that different art units within TC 2100 have produced different allowance rates in this examiner's record. Pooled data does not isolate which art unit will examine a given application or how that specific unit's dynamics will affect prosecution.

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 Christopher N Do 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: 83 applications.

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.
