Data preview
Dataset card
EP granted patent claim sets from the European Patent Office, distributed by Hugging Face user mhurhangee. The dataset compiles one claim per row across roughly 4.4 million rows from September 2021 through August 2025.
What this dataset contains
The dataset consists of text records of granted EP patent claims, with each row representing a single independent or dependent claim. Coverage spans the period 2021-09-15 to 2025-08-06, providing a recent snapshot of European patent grant activity. Sample rows include excerpted claim language from mechanical domains such as wellbore drilling and motor vehicle seat protective films.
Structure and fields
Records are distributed in parquet format and split across train, validation, and test partitions totaling 4,420,734 rows. The sole documented column is text, stored as a string Value type, holding the raw claim text. The dataset is tagged with the cc-by-4.0 license and is compatible with the datasets, dask, polars, and mlcroissant libraries.
How analysts use it
Investors and IP analysts can mine the text field to monitor patent grant volumes by technology area or to train NLP models that classify claim scope and detect litigation-relevant language. The data also supports tracking filing-to-grant trends among European applicants, which can inform assessments of corporate innovation pipelines. Licensing under CC-BY-4.0 permits reuse with attribution, though the publisher license field is marked unstated.
