Examiner Chuck O Kendall has allowed 1,059 of 1,227 decided applications in Computer Architecture, Software, and Information Security.
Chuck O Kendall maintains a public record across 2 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Across more than a thousand decided applications, his pooled allowance rate stands at 86%. The allowance rate ranges from 55% to 87% across these art units, reflecting variation in the record by art-unit assignment. This pooled figure represents the proportion of decided applications—those allowed or abandoned—and does not include pending matters.
A pooled record aggregates data across multiple art units, presenting a single allowance-rate figure that combines outcomes from different subject areas and examiner assignments. This aggregate describes past outcomes and is a historical profile, not a prediction about any specific application. The range between art units indicates that outcomes vary by art-unit context. Applicants review pooled records to understand an examiner's overall record; per-art-unit detail appears in a separate section.
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 software engineering.
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 233 decided applications with an interview and 974 without.
Primarily examines neural-network / biological-model computing, and machine learning.

Methodology. This page pools every art unit in which Examiner Chuck O Kendall 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: 1,265 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. 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.
