What the data says.

David A Spellman maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning one art unit. Across 48 disposed applications, 9 were allowed and 39 were abandoned, yielding an allowance rate of 19% over the decided caseload. This rate reflects the examiner's pooled record and represents the proportion of applications that resulted in allowance among all concluded matters, exclusive of pending applications.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This pooled record aggregates the examiner's work across all art units under their purview. The allowance rate and application counts reflect historical outcomes across that full scope and describe the past record only. These figures are not predictions about any specific application. Pooled data combines different subject areas and prosecution patterns; the aggregate rate does not forecast results in individual cases.

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

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner David A Spellman 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: 48 applications.

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.
