An intermediate dataset for US molecular patent grants Retrieves patent grant data from USPTO weekly releases bulkdata.uspto.gov/data/patent/grant/redbook/{year} and keeps only patents with .mol files for downstream data mining use cases. Compared to existing work such as [https://github.com/learningmatter mit/PatentChem/tree/main]. We keep all files of a patent grant, especially .til image files. We also share the data as a git lfs repo instead of a single .zip file to allow easier access. The data directory Each file is a full patent grant with original redbook directory structure preserved. weekly is the weekly release date. Expect inconsistencies for the formate of weekly and depth in sub dir over time. See [https://www.uspto.gov/learning and resources/xml resources] for DTD and Red Book Viewer. Data quality Ideally, USPTO provides the ground truth on chemical structure annotations for the molecular drawings. But the raw data quality appears poor. Some outlandish annotations such as chemical structure annotations on non chemistry related images suggest an automated annotation process with little human QA is used to annotate the drawings. A report on improving data quality is le…
