What the data says.reading this examiner

Brian P Whipple maintains a pooled allowance rate of 89% across more than a thousand decided applications in Technology Center 2400. His record spans 6 art units within this technology center. The allowance rate ranges from 52% to 97% across these art units, reflecting variation in the composition and outcomes of applications handled in different art-unit groups. This pooled figure represents the share of decided applications (allowed and abandoned combined) that resulted in allowance, and does not include pending applications.

How to read these numbers.

This examiner's pooled record aggregates applications across multiple art units. The overall allowance rate describes the examiner's past record and reflects the combined outcomes of decided applications across all art units served. Such aggregate figures describe historical outcomes and are not predictions for any specific application. Individual art units may show different allowance rates; those rates appear in the art-unit-specific section of this page.

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 Brian P Whipple 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: 1,060 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.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
