Largest Patent Holdings

posted on Sep 06, 2014 07:59PM

Of the more than 830 NPEs profiled by PatentFreedom as of July 2014, only 48 are known to hold more than 100 active patent publications in their portfolios. With portfolios of this size, potential licensees can readily assess the potential risk of the portfolio provided they can learn all of the patents owned by the NPE, a complex and expensive exercise that is made easier by PatentFreedom.

The table below ranks NPEs by the number of active patent holdings known and identified by PatentFreedom.
