Examiner Ivan Alexander Castaneda has allowed 3 of 5 decided applications (60%) in Computer Architecture, Software, and Information Security.
Examiner Ivan Alexander Castaneda maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 43 total applications, 5 have been disposed of (allowed or abandoned). Of those 5 decided applications, 3 were allowed, yielding an allowance rate of 60%. The examiner's work spans a single art unit. This pooled record reflects outcomes on applications that have reached a final decision; pending applications are not included in the allowance-rate calculation.
This record aggregates all of the examiner's applications across their art unit(s) in TC 2100. The allowance rate describes past dispositions and reflects the share of decided cases that issued as allowed. Aggregate figures describe the examiner's historical record and are not predictions about the outcome of any specific application. Individual art-unit records, where available separately, provide additional detail on subject-matter-specific patterns.
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 program control and execution.
Based on 43 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Methodology. This page pools every art unit in which Examiner Ivan Alexander Castaneda 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 June 25, 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: 43 applications.

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.
