Examiner Tewodros E Mengistu has allowed 72 of 140 decided applications (51%) in Computer Architecture, Software, and Information Security.
Tewodros E Mengistu has a public record spanning 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 140 decided applications, the allowance rate is 51%. The allowance rate ranges from 46% to 53% across the examiner's art units. This pooled figure represents applications that were either allowed or abandoned; pending applications are excluded from the calculation. The record reflects dispositions in art units 2121 and 2127.
A pooled record aggregates data across multiple art units, presenting a combined allowance rate rather than separate rates for each unit. The overall allowance rate of 51% describes the examiner's historical record across all their art units and is not a prediction of any specific application. Allowance rates are calculated from decided applications only. Separate, detailed rates for each individual art unit are available elsewhere on 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 →
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 neural-network / biological-model computing, and machine learning.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 91 decided applications with an interview and 21 without.
Primarily examines neural-network / biological-model computing, and machine learning.
Based on 28 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Methodology. This page pools every art unit in which Examiner Tewodros E Mengistu 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: 192 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.
