What the data says.

Examiner Alvaro Rafael Calderon Santiago has a pooled public record of 319 total applications across Technology Center 2100 (Computer Architecture, Software, and Information Security).

This pooled figure—43% across 281 decided cases—describes the examiner's historical record and does not constitute a prediction for any individual application.

// HOW TO READ THESE NUMBERS

How to read these numbers.

A pooled record aggregates decisions across multiple art units into a single allowance rate. This aggregate figure describes past outcomes and reflects the examiner's overall profile across the units represented, but it is not a prediction of any specific application's outcome. Individual art units may show different rates. Allowance rate is calculated as allowed applications divided by disposed (decided) applications; pending cases are excluded.

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 →
