The Economic Value of Patent Portfolios
Gambardella, Alfonso; Harhoff, Dietmar; Verspagen, Bart - C.E.P.R. Discussion Papers - 2013
Patent holders may choose to protect innovations with single patents or to develop portfolios of multiple, related inventions. We propose a simple decision-making model in which patent-holders may allocate resources to either expanding the number of related patents or investing in higher value...
