Patent database for Australian listed companies

Patent data is sourced from the Australian Government’s Intellectual Property Government Open Data (IPGOD) 2019 (https://data.gov.au/dataset/ds-dga-a4210de2-9cbb-4d43-848d-46138fefd271/details?q=patent%202019). Companies are identified as a recipient of a patent if their current or historical company names, or the names of their controlled subsidiaries are named as the patent applicant in IPGOD. The standardisation and matching process is conducted following Mann (2018) and Kogan et al. (2017a, 2017b). Patent applicant and company/subsidiary names are rigorously cleaned and standardised by removing symbols (e.g., “,” or “@”) and common words (e.g., “Limited” or “Ltd”) for matching. The matching procedure is conducted following Mann (2018) and Kogan et al. (2017a, 2017b) using the Levenshtein distance. A full breakdown of the database construction is provided in Bedford et al. (2020).
