What the data says.reading this examiner

D'Arcy Winston Straub maintains a public record in Technology Center 2400 across one art unit. His pooled allowance rate is 79% across hundreds of decided applications. This rate reflects the share of applications that were allowed among all decided applications (allowed and abandoned) in his record. The 79% allowance rate represents his historical disposition of applications within TC 2400. This record is descriptive of past decisions and does not constitute a prediction for any specific pending or future application.

How to read these numbers.

This pooled record aggregates all of the examiner's decided applications across his art unit(s) in TC 2400. The allowance rate is a historical aggregate and describes past dispositions only—it is not a prediction of the outcome of any particular application. Pooled figures reflect the examiner's overall record and are useful for understanding the historical context of examination in this technology center, but individual application outcomes depend on claim scope, prior art, and prosecution conduct.

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 D'Arcy Winston Straub has a public record within Technology Center 2400. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 22, 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: 290 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.
