What the data says.reading this examiner

Philip C Lee maintains a pooled allowance rate of 80% across hundreds of decided applications in Technology Center 2400. His record spans five art units: 2447, 2448, 2452, 2453, and 2454. The allowance rate—the share of applications resulting in allowance or abandonment—ranges from 47% to 87% across these art units, reflecting variation in outcomes within the examiner's portfolio. This pooled figure represents the historical record and does not predict outcomes in any individual application.

How to read these numbers.

A pooled record aggregates decided applications across multiple art units into a single overall statistic. The 80% allowance rate describes past outcomes across all five units combined. This aggregate figure is descriptive of what has occurred, not predictive of what will occur in any future or pending application. Individual art units may show higher or lower rates; the pooled figure reflects the examiner's overall pattern.

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 Philip C Lee has a public record within Technology Center 2400. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 22, 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: 449 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. 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.
