What the data says.reading this examiner

Chae S Lee maintains a public record in Technology Center 2400 across one art unit. The examiner's pooled allowance rate is 88%, calculated as the share of allowed applications among all decided (allowed and abandoned) applications across hundreds of decided applications. This rate represents the examiner's historical record and describes outcomes on applications already resolved. The record reflects decisions made within the assigned art unit and does not constitute a prediction for any specific pending application.

How to read these numbers.

This pooled record aggregates decisions across all art units where the examiner works. The 88% allowance rate is a historical average derived from hundreds of decided applications and describes past outcomes only. Pooled figures mask variation that may exist within individual art units. Aggregate statistics describe the examiner's overall record and are not predictions about how any particular application will be examined or decided.

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 →

Questions about Examiner Chae S Lee

  • What is this examiner's allowance rate?
    Chae S Lee's pooled allowance rate is 88%, meaning that 88% of the examiner's decided applications (allowed and abandoned) were allowed. This figure is derived from hundreds of decided applications across all assigned art units.
  • How many art units does this examiner work in?
    The examiner works in one art unit within Technology Center 2400. The pooled record shown here combines all decisions made across that assignment.
  • Does this allowance rate apply to my application?
    No. This pooled allowance rate is a historical summary and is not a prediction of any specific application's outcome. Individual applications are examined based on their own merits under applicable patent law.
  • What does 'decided applications' mean?
    Decided applications are those that have been allowed or abandoned. Pending applications are excluded from this calculation. The 88% allowance rate reflects only applications with final outcomes.

METHODOLOGY & DISCLOSURES

Methodology. This page pools every art unit in which Examiner Chae S 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: 443 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.
