Examiner Aleksandr Kerzhner has allowed 174 of 250 decided applications in Computer Architecture, Software, and Information Security.
Aleksandr Kerzhner maintains a public record across 3 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over hundreds of decided applications, the examiner's pooled allowance rate is 70%. This rate represents the share of applications in the decided category—those allowed or abandoned—and excludes pending applications. The allowance rate ranges from 39% to 74% across the examiner's art units, reflecting variation in outcomes by subject area within the technology center.
This record aggregates data from multiple art units into a single pooled figure. The 70% allowance rate describes the examiner's historical record across all decided applications and reflects past dispositions only. Pooled figures do not account for differences among individual art units and are not predictions of outcomes in any specific application. They provide context for the examiner's overall record in TC 2100.
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 information retrieval and database structures.
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 66 decided applications with an interview and 152 without.
Primarily examines information retrieval and database structures.
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.
Based on 33 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.

Methodology. This page pools every art unit in which Examiner Aleksandr Kerzhner 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: 252 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.
