PitchBook provides patent data in its company profiles, including number and status of patents; backwards and forwards citations; and type of technology by Cooperative Patent Classification (CPC) section, class, and subclass. More information on individual patents is also available, including filing documents, patent publication ID, inventor name, patent family ID, and CPC code numbers/descriptions.
Lens.org is a free resource where you can find patent data across companies, as it allows searching by keyword and classification (CPC, IPC, or US). Once you initiate a search, there are a myriad of filters you can utilize to focus your results, including company, inventor, status, jurisdiction, and more.
Click on the small folder icon to reveal more/narrower class subdivisions. Click the "New Patent Search" button to reveal your results after checking your desired selection boxes.
