What the data says.reading this examiner

Alan Louis Lindenbaum maintains a pooled allowance rate of 50% across hundreds of decided applications in Technology Center 2400. His record spans three art units: 2413, 2419, and 2466. The allowance rate ranges from 45% to 92% across these art units, reflecting variation in the decided applications within each. This pooled figure represents applications that have reached a final disposition—either allowed or abandoned—and does not include pending applications.

How to read these numbers.

A pooled record aggregates decided applications across multiple art units, smoothing individual unit differences into a single overall rate. This aggregate figure describes the examiner's historical record and reflects the mix of applications and dispositions across all assigned art units. Pooled statistics are descriptive of past performance and are not predictions about any specific application or art unit.

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 Alan Louis Lindenbaum 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: 514 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.
