BAL FENTON DATA SET LORETT 2026
Description
This dataset contains 31,595 patent documents retrieved through systematic data mining on Google Patents Public Datasets (patents-public-data.patents.publications) via Google BigQuery, covering the period 2010–2026. The dataset was generated as part of a Freedom to Operate (FTO) analysis for a technology based on the oxidation of dimercaprol (British Anti-Lewisite, BAL) via a Fenton-type process for the therapeutic and localized generation of hydrogen sulfide (H₂S). Documents are organized into three thematic blocks: (1) therapeutic applications of H₂S and gasotransmitters (8,392 documents), (2) medical and synthetic uses of dimercaprol/BAL (606 documents), and (3) Fenton-type reactions and thiol-oxidative processes generating small molecules including H₂S (22,597 documents). Retrieval was performed using multilingual Boolean queries (English, Spanish, French, German, Chinese, Japanese) applied to title, abstract, and claims fields. Each record includes publication number, publication date, country code, patent family ID, title, abstract, IPC classification, CPC classification, and assignees. The dataset was processed and deduplicated using Python (pandas), resulting in 31,595 unique records across 22,514 patent families. It serves as the primary input for the KNIME-based depuration and IPC filtering workflow described in the associated methodology. The SQL script used for data extraction is provided as supplementary material.
