What the data says.

Examiner Hosuk Song maintains a public record across 2 art units in Technology Center 2100 (Computer Architecture, Software, and Information Security). Over 276 disposed applications, 242 were allowed and 34 were abandoned, resulting in an 88% allowance rate. This rate describes the examiner's historical record of decided cases and reflects outcomes across both assigned art units on a pooled basis. The allowance rate is computed from disposed applications only and does not include pending filings.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates data from multiple art units into a single statistic. The 88% allowance rate reported here is the examiner's combined record across 2 different art units and reflects past dispositions. This aggregate figure describes what has occurred, not what will occur in any individual application. Art units within TC 2100 may have different subject matter, and pooled rates mask variation between them; per-art-unit detail is available separately.

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 Hosuk Song 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: 276 applications.
