Bargaining failure and freedom to operate: Re-evaluating the effect of patents on cumulative innovation
Gaessler, Fabian; Harhoff, Dietmar; Sorg, Stefan - 2019
We investigate the causal effect of patent rights on cumulative innovation, using large-scale data that approximate the patent universe in its technological and economic variety. We introduce a novel instrumental variable for patent invalidation that exploits personnel scarcity in post-grant...

Patents, freedom to operate, and follow-on innovation: Evidence from post-grant opposition
Gäßler, Fabian; Harhoff, Dietmar; Sorg, Stefan; von … - 2024
We study the blocking effect of patents on follow-on innovation by others. We posit that follow-on innovation requires … patents on low-value original innovations, invalidation predominantly increases low-value followon innovation outside the … contrast, for patents on high-value original innovations, invalidation mainly increases high-value follow-on innovation in the …

Truly standard-essential patents? A semantics-based analysis
Brachtendorf, Lorenz; Gäßler, Fabian; Harhoff, Dietmar - 2020
Standard-essential patents (SEPs) have become a key element of technical coordination in standard-setting organizations … approximating the standard essentiality of patents. We provide details on the procedure that generates the measure of standard …

The Economic Value of Patent Portfolios
Gambardella, Alfonso - 2017
Patent holders may choose to protect innovations with single patents or to develop portfolios of multiple, related … patents. We propose a decision-making model in which patent holders allocate resources to either expanding the number of … related patents or investing in higher value of patents in the portfolio. We estimate the derived value equation using …
