Examiner Sen Thong Chen has allowed 106 of 158 decided applications in Computer Architecture, Software, and Information Security.
Examiner Sen Thong Chen's public record spans 2 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Across hundreds of decided applications, the examiner's pooled allowance rate is 67%. This aggregate figure reflects allowed and abandoned applications only; pending applications are excluded from the calculation. The allowance rate ranges from 62% to 79% across the examiner's art units, indicating variation in outcomes by subject-matter area within TC 2100. The pooled 67% rate represents the examiner's overall historical record across these distinct art units.
This profile aggregates the examiner's record across multiple art units in TC 2100. A pooled allowance rate describes past dispositions and does not predict the outcome of any specific application. The range shown reflects differences in allowance rates among the examiner's individual art units; the aggregate 67% is a summary across all decided applications in those units. Historical statistics provide context for past decisions and do not indicate how any future application will be examined or decided.
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, and software engineering.
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 55 decided applications with an interview and 56 without.
Primarily examines program control and execution.
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 47 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.

Methodology. This page pools every art unit in which Examiner Sen Thong Chen 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: 158 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.
