Examiner Fen Christopher Tamulonis has allowed 53 of 102 decided applications (52%) in Computer Architecture, Software, and Information Security.
Fen Christopher Tamulonis maintains a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security) spanning 2 art units. Across 102 disposed applications, the examiner allowed 53 and abandoned 49. The allowance rate is 52% of decided applications. This pooled figure reflects the examiner's combined record across multiple art units and represents the historical rate at which applications were allowed relative to total disposed counts. The record does not include pending applications.
This pooled record aggregates data across all art units where the examiner works. The 52% allowance rate describes the past disposal record and is calculated from decided applications only—pending cases are excluded. Pooled figures represent the examiner's overall history, not a prediction of any specific application's outcome. Art-unit-specific records, where available separately, may show variation and are independent of this aggregate summary.
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 71 decided applications with an interview and 21 without.
Primarily examines neural-network / biological-model computing, and machine learning.
Based on 10 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Methodology. This page pools every art unit in which Examiner Fen Christopher Tamulonis 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: 102 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.
