Examiner Yicun Wu has allowed 809 of 970 decided applications in Computer Architecture, Software, and Information Security.
Yicun Wu maintains an 83% allowance rate across hundreds of decided applications in Technology Center 2100 (Computer Architecture, Software, and Information Security). The examiner's record spans 5 art units within this technology center. The allowance rate—computed as allowed applications divided by all decided applications (allowed and abandoned combined)—represents the examiner's historical disposition on decided matters. Allowance rates vary across the examiner's art units, ranging from 76% to 96%. This pooled figure aggregates that variation and does not describe the rate for any single art unit.
A pooled record combines data from multiple art units into a single aggregate profile. The overall allowance rate reflects historical outcomes across all of the examiner's art units combined and describes past dispositions, not predictions for any individual application. The range shown (76% to 96%) indicates that allowance rates differ among the art units the examiner works in. Pooled statistics are useful for general context; detailed per-art-unit breakdowns appear 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 →
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.
Primarily examines information retrieval and database structures.
Grounds can co-occur, so the four don't sum to 100%. The art-unit figure is the unweighted mean across examiners in the art unit; §102 and §112 carry no art-unit benchmark.

Methodology. This page pools every art unit in which Examiner Yicun Wu 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 July 14, 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: 992 applications.
Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes.
