What the data says.reading this examiner

Luis M Perez Fuentes maintains an allowance rate of 85% across hundreds of decided applications in Technology Center 2400. His public record spans one art unit. The allowance rate reflects the percentage of applications that have been allowed or abandoned, excluding pending matters. This figure is pooled across all art units in his portfolio and describes his historical record of dispositions on decided applications. The 85% rate represents the share of decided applications resulting in allowance or abandonment rather than the share of all filings received.

How to read these numbers.

This pooled record aggregates all decided applications across every art unit in the examiner's portfolio. Aggregate figures describe the examiner's past disposition patterns and do not constitute predictions about any individual application. A single allowance-rate percentage masks variation that may exist across different art units or technology areas. Pooled data provides general context for the examiner's historical record but does not forecast outcomes in any specific prosecution.

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 Luis M Perez Fuentes 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: 820 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.
