- •
We identify buyers of Ocean Tomo's patent auctions from the USPTO reassignments.
- •
We study firms and NPEs (super-, defensive aggregators) along patent dimensions.
- •
NPEs prefer less complex, legally robust, hot technologies with international scope.
- •
Defensive aggregators prefer higher technical merit and longer residual life.
- •
Intellectual Ventures prefers longer residual life and more assignees.
