When the U.S. patent data was filtered by company size, it was found that companies with over $10 billion in sales filed about 10x more than smaller entities with sales <$100 million. Also, as the “Portfolio Preservation by Company Size” figure shows, larger entities also retain more of their portfolios over time: almost 16% more. It is speculated that this might be because (1) of the higher resource level of the larger companies (smaller companies would maintain more of their portfolios if they could), and (2) larger entities have the ability to fund licensing-out activities and obtain value from tangential art that smaller companies don’t.
