IPqwery? has produced a nice overview of the intellectual property held by companies within Crunchbase’s Unicorn Leaderboard.
Note: Aggregating this data is not trivial. There are many data manipulations required to accurately compile the IP profile for any company, Unicorn or otherwise. This includes normalizing company names, verifying subsidiary companies and grouping related entities, and even match inventors with their respective companies.
To investigate how this works in more detail, check out the IPqwery? Chrome extension and test it out yourself on Crunchbase.
