Assignee Name Cleaning: here is a link to a crosswalk (.dta) that maps PatentsView assignee identifiers (USPTO) to cleaned and harmonized assignee names (variable 'new_assignee_name'). Example: for 'Microsoft Corporation' and 'Microsoft Technology Licensing, LLC',  'new_assignee_name' assigns the value of 'Microsoft'.  If you use this crosswalk, please cite: 'Dossi, G., and Morando, M., 2023, Political Ideology and Innovation, CEP Discussion Paper N. 1969'.
