// HOW TO READ THESE NUMBERS

How to read these numbers.

This profile aggregates the examiner's record across all assigned art units in TC 2100. The allowance rate and application counts describe historical outcomes only—they are a summary of past decisions, not a forecast for any individual application. Different art units within the technology center may have distinct subject-matter scope. Pooled figures mask variation; per-art-unit detail appears in a separate section of this page.

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 →

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Phuong Thao Cao 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.

Figures are rounded for display. Pooled sample: 929 applications.

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.
