Examiner Tracy C Chan has allowed 387 of 466 decided applications (83%) in Computer Architecture, Software, and Information Security.
Tracy C Chan maintains an 83% allowance rate across 466 disposed applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner's record spans two art units, with allowance rates ranging from 75% to 89% across these units. Of 501 total applications on record, 387 were allowed and 79 were abandoned. This pooled figure represents decided cases only and does not include pending applications. The range reflects variation in allowance rates among the individual art units within TC 2100.
This profile aggregates the examiner's record across multiple art units within TC 2100. The overall allowance rate of 83% describes historical dispositions and is a pooled statistic, not a prediction of the outcome of any particular application. Art units within the technology center show different allowance rates; the aggregate figure masks this variation. Each application is examined on its individual merits according to patentability law, independent of historical rates.
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.

Methodology. This page pools every art unit in which Examiner Tracy C Chan 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: 501 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.
