Examiner Phil K Nguyen has allowed 548 of 643 decided applications (85%) in Computer Architecture, Software, and Information Security.
Phil K Nguyen maintains a public record spanning 4 art units within Technology Center 2100 (Computer Architecture, Software, and Information Security). Across 643 disposed applications, the examiner issued allowances in 548 cases, yielding an overall allowance rate of 85%. The record covers multiple art units (2115, 2118, 2176, 2187), and allowance rates across these units range from 72% to 98%. This pooled figure represents applications that were either allowed or abandoned; pending applications are excluded from the calculation.
This profile aggregates the examiner's record across four separate art units in TC 2100. Pooled allowance rates combine different subject-matter areas and examination patterns into a single figure. The overall 85% rate describes past dispositions and is not a prediction of any specific application's outcome. The range (72% to 98%) reflects variation among individual art units; detail on per-unit performance appears in the separate art-unit 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. This page pools every art unit in which Examiner Phil K Nguyen 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: 684 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.
