Examiner Li B Zhen has allowed 152 of 294 decided applications (52%) in Computer Architecture, Software, and Information Security.
Examiner Li B Zhen maintains a public record spanning 4 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 294 disposed applications, the examiner allowed 152, for an overall allowance rate of 52%. This rate reflects decided applications only—allowed and abandoned combined—and excludes pending matters. The allowance rate varies across the examiner's art units, ranging from 9% to 61%. The pooled figure aggregates work across multiple art units and describes the examiner's historical record without predicting outcomes in any individual application.
A pooled record aggregates an examiner's statistics across multiple art units, creating an overall snapshot rather than unit-specific data. The allowance rate presented here—52% over 294 decided applications—is a historical summary and is not a prediction of any specific application's outcome. Variation across art units (9% to 61%) reflects differences in subject matter or application complexity within TC 2100. Pooled figures describe what has occurred; they do not indicate what will occur in any pending matter.
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.
Allowance rate for applications with an examiner interview versus without one.
A correlation, not proof that interviews cause allowances. Based on 121 decided applications with an interview and 110 without.
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 17 decided applications with an interview and 29 without.
Primarily examines program control and execution, and software engineering.
Based on 9 applications — too small a sample to characterize the rejection mix reliably; shown for completeness.
Primarily examines neural-network / biological-model computing, and machine learning.
Methodology. This page pools every art unit in which Examiner Li B Zhen 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: 301 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.
