+# 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
+
+Contact Arbitr Inc ([email protected]) or reference the main `arbitr-uspto-ev` package for production-sized exports covering 2015–2025 with CPC/keyword filters tuned for Electric Vehicle R&D.
+
+## License
+
+See `LICENSE_Arbitr_Commercial.txt`. Public use must include:
+
+> © Arbitr Inc, 2025. Derived from public-domain sources (e.g., USPTO). No affiliation or endorsement by USPTO.
