# Arbitr USPTO EV Dataset — Sample Release

This repository contains a lightweight sample of the full `arbitr-uspto-ev` dataset so you can inspect the schema, directory layout, and licensing terms on Hugging Face before downloading the complete archive.

## What's Inside

- `data/patents/patents_2025-10.parquet` — 200-row slice from the Oct 2025 granted-patent export (PTGRDT).
- `data/applications/applications_2025-10.parquet` — 200-row slice from the Oct 2025 application export (APPDT).
- `data/texts/texts_sample.jsonl.gz` — same JSONL claims sample provided in the full dataset.
- `data/provenance/` — provenance summary + download log for this sample.
- `metadata/` — schemas, CPC whitelist, and machine-readable manifest matching the on-disk structure.
- `LICENSE_Arbitr_Commercial.txt` — Arbitr Inc Commercial Dataset License v1.1 (required for redistribution).
- `CHANGELOG.md` — release history for the sample package.

## Purpose

- Give Hugging Face users a quick preview of the normalized schema and CPC filtering.
- Provide a minimal artifact (<1 MB) for automated tests.
- Document licensing and provenance in the same layout as the production dataset.

## Using the Sample

```python
import pandas as pd

patents = pd.read_parquet("data/patents/patents_2025-10.parquet")
applications = pd.read_parquet("data/applications/applications_2025-10.parquet")
```

The schema is identical to the full release, so any pipelines built against this sample will work against the larger dataset (subject to licensing).

## Getting the Full Dataset
