What the data says.

Karen C Tang holds a public record in Technology Center 2100 (Computer Architecture, Software, and Information Security). Across her pooled record, 60 applications have been disposed. Of those decided applications, 20 were allowed and 40 were abandoned, resulting in an allowance rate of 33%. This figure reflects outcomes across a single art unit. The allowance rate is a summary of past dispositions and does not indicate the outcome of any pending or future application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

This examiner's record spans one art unit and is presented as a pooled aggregate. Pooled figures combine all decisions across assigned art units and describe the historical record only. An aggregate allowance rate describes past outcomes across different application types and circumstances within TC 2100. Aggregate figures are not predictions about individual applications and do not account for variations by claim scope, prosecution history, or other case-specific factors.

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 →

// BY ART UNIT

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 & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Karen C Tang 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: 60 applications.

Lynch LLP is not affiliated with, endorsed by, or sponsored by the United States Patent and Trademark Office. Examiner statistics are derived from publicly available USPTO data.

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.
