Details

Field names in this dataset have been simplified from their original long form to make them easier to work with in R. Patent data fields are commonly concatenated with a semicolon and require tidying for accurate counts. The cited_nonpatent field in this dataset contains irrelevant legal status information and is messy. Applicant names (assignees) were cleaned using VantagePoint by fuzzy matching names grouped on the priority number followed by manual review. In the second step the cleaned data was fuzzy match grouped on the INPADOC family member number.
