Patent Documents: Google Patents contains over 120 million patent publications from 100+ patent offices worldwide, available for open access searching . For the current work, a set of 111,730,728 Google Patent documents semantically annotated with OC|processor in May 2021 using both the text and images found in these patents was used. The resulting annotations are available in a BigQuery table in the SciWalker-Open-Data project . As a next (pre-filtering) step, the 18,032,261 unique compounds from the chemistry annotations of patents were reduced to a dataset of 4,182,712 SMILES that contained an "F" character, resulting from a fluorine, iron or francium atom.
