The valuation of patents using third-party data: the Ocean Tomo 300 Patent Index

Applied Economics, 2016, vol. 48, issue 42, 3995-3998

Abstract: This study is the first investigation of the ability of the financial marketplace to value patent assets via exploiting the informational content of a widely quoted stock market patent index known as the Ocean Tomo 300 Patent Index (OT 300). The results suggest that the OT 300 ‘works,’ in the sense that the index generates buy-and-hold returns economically and statistically in excess of those of the market as a whole as well as a specially created 300-firm benchmark portfolio composed of other very liquid patent-holding firms.
