Conflict Resolution, Public Goods, and Patent Thickets
Post-grant validity challenges at patent offices rely on the private initiative of third parties to correct mistakes made by patent offices. We hypothesize that incentives to bring post-grant validity challenges are reduced when many firms benefit from revocation of a patent and when firms are caught up in patent thickets. Using data on opposition against patents at the European Patent Office w...
متن کاملPatent Thickets, Trolls and Unproductive Entrepreneurship
I introduce and analyze an equilibrium model of invention, patenting and infringement under monopolistic competition. Profitable use of inventions requires adaptation to complementary technologies. With patents, a thicket of conflicting rights emerges and costly infringements occur. This taxes invention and lowers welfare. When an inventor may be a “troll”—patent without inventing—the rate of i...
متن کاملPatent Thickets, Licensing and Innovative Performance
We examine the relationship between fragmented intellectual property (IP) rights and innovative performance, taking into consideration the role played by in-licensing of IP. Controlling for a variety of firm and market characteristics, we find that firms facing more fragmented IP landscapes are more likely to report expenditures on in-licensing and for those firms that do incur license costs we...
متن کاملPatent Thickets: Strategic Patenting of Complex Technologies
Patent race models assume that an innovator wins the only patent covering a product. But when technologies are complex, this property right is defective: ownership of a product’s technology is shared, not exclusive. In that case I show that if patent standards are low, firms build “thickets” of patents, especially incumbent firms in mature industries. When they assert these patents, innovators ...
