Examiner April Ying Shan Blair has allowed 82 of 108 decided applications (76%) in Computer Architecture, Software, and Information Security.
April Ying Shan Blair maintains a pooled allowance rate of 76% across 108 disposed applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). Her public record spans 6 art units: 2111, 2117, 2135, 2187, 2191, and 2196. Of 143 total applications, 82 were allowed and 26 abandoned. The allowance rate across her art units ranges from 61% to 100%, reflecting variation in her record within TC 2100. This pooled figure aggregates her work across multiple art units and represents her historical disposition record only.
A pooled allowance rate aggregates an examiner's performance across multiple art units into a single figure. This rate describes past dispositions—applications decided as either allowed or abandoned—and does not constitute a prediction about any specific application. The range shown reflects differences in allowance rates among individual art units; the pooled rate is a weighted summary across all units in the examiner's record. Pooled data provides context for an examiner's overall record but does not predict outcomes on particular cases.
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.
Primarily examines input/output (I/O) data transfer, and memory access and allocation.
Primarily examines computer-aided design (CAD).

Methodology. This page pools every art unit in which Examiner April Ying Shan Blair 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: 143 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.
