Examiner Dayton A. Lewis-Taylor has allowed 618 of 753 decided applications 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). Across hundreds of decided applications, the examiner's allowance rate is 82%. The allowance rate ranges from 54% to 85% across these art units. This pooled figure represents the share of allowed applications among all decided cases—those allowed and abandoned combined—and reflects the examiner's historical record without regard to application status or pending matters.
This record aggregates data from multiple art units under TC 2100. The pooled allowance rate reflects past decisions across all art units combined and describes historical outcomes only. Aggregate figures do not constitute predictions about any specific application. Applicants may review the separate per-art-unit detail to understand variation in allowance rates by individual art unit.
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.
Grounds can co-occur, so the four don't sum to 100%. The art-unit figure is the unweighted mean across examiners in the art unit; §102 and §112 carry no art-unit benchmark.
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.
Grounds can co-occur, so the four don't sum to 100%. The art-unit figure is the unweighted mean across examiners in the art unit; §102 and §112 carry no art-unit benchmark.

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 July 14, 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.
Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes.
