Examiner Demetrios C Kerveros has allowed 1,374 of 1,590 decided applications in Computer Architecture, Software, and Information Security.
Demetrios C Kerveros has a pooled allowance rate of 86% across more than a thousand decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). His public record spans four art units: 2111, 2117, 2133, and 2138. The allowance rate ranges from 82% to 93% across these art units. This pooled figure represents the share of his decided applications (allowed and abandoned combined) that resulted in allowance, and does not include pending applications.
A pooled record aggregates an examiner's activity across multiple art units and different subject-matter areas within TC 2100. The overall allowance rate describes past disposition patterns and is not a prediction of outcome for any specific application. The range across art units reflects variation in how applications have been decided within different specialties. Pooled figures are historical summaries, not predictive tools.
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 control or regulating systems.
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 Demetrios C Kerveros 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: 1,629 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.
