Examiner Dayton A. Lewis-Taylor has allowed 618 of 753 decided applications (82%) in Computer Architecture, Software, and Information Security.
Dayton A. Lewis-Taylor maintains a public record across 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 753 decided applications, the examiner's allowance rate stands at 82%, based on 618 allowed and 135 abandoned applications. The allowance rate ranges from 54% to 85% across these art units, reflecting variation in outcomes across different subject areas within TC 2100. This pooled figure aggregates the examiner's work across multiple art units and describes the historical record without predicting outcomes for individual applications.
This record pools decisions across multiple art units within a single technology center. The 82% allowance rate reflects past outcomes on 753 decided applications—allowed and abandoned combined—and does not predict the disposition of any specific application. The range of 54% to 85% across art units illustrates that allowance rates vary by subject matter. Aggregate statistics describe historical performance and are correlational, not causal, indicators of how applications progress.
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 →
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.
Primarily examines interconnection and data transfer between memory, I/O, and processing units, and program control and execution.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 146 decided applications with an interview and 539 without.
Primarily examines data-processing methods for specific functions, and processing data by its order or content.
Methodology. This page pools every art unit in which Examiner Dayton A. Lewis-Taylor 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: 790 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.
