Coarse Cleaned EP Patents
This dataset contains the description and first claim from granted European Patent (EP) documents that have been cleaned for NLP tasks such as pretraining language models.
Contains one years worth of English granted EP patents from 04 September 2024 to 04 Sep 2025.
Each line is a JSON object representing a single patent with the following fields:
description: The cleaned English description text.claim1: The cleaned first claim in English.
Cleaning and Processing Steps
Language Filtering
- Only patents with an English description (
<description lang="en">) are included. - Only the first claim (
<claims lang="en"><claim num="0001">) is extracted.
- Only patents with an English description (
Text Extraction
- Text is extracted recursively from child XML elements.
- Paragraphs (
<p>) are preserved and separated by double newlines (\n\n).
Special Token Replacement
Certain XML tags are replaced with tokens, with the original content removed:<table>→<TAB><img>→<IMG><figref>→<FIG><patcit>→<CIT><nplcit>→<NPL><chemistry>→<CHM><maths>→<MAT><heading>→<HEAD><ol>,<ul>,<dl>→ removed entirely
Number Normalization
- Numbers with optional SI units (e.g., "20 mm", "3.5 kg") are replaced with
<NUM>. - Numbers inside words like "CO2" are preserved.
- Numbers with optional SI units (e.g., "20 mm", "3.5 kg") are replaced with
Whitespace Normalization
- Redundant spaces are removed.
- Paragraph separation is maintained using double newlines.
Comments Removal
- XML comments such as
<!-- EPO <DP n="1"> -->are removed.
- XML comments such as
Trimmed outliers
- Longest 10% of claims and descriptions (seperately) removed.
- Shortest 2% of claims and descriptions (seperately) removed.
Exact deduping
- Removed exact duplicates based on claim1 and description.
Paragraph outliers
- Removed paragraphs less than 40 characters long.
- Removed paragraphs greater than 10240 characters long.
- Removed duplicate paragraphs within same document.
Output Format
- Saved as JSONL, one patent per line.
- Suitable for downstream NLP processing, including language model pretraining.
