This paper looks at the special characteristics of radical inventions. It tries to identify those variables that differentiate radical inventions from non-radical inventions. Since radical inventions are very important for the economy as a whole and for the individual firm performances,...

Strategic patenting is widely believed to raise the costs of innovating, especially in industries characterised by cumulative innovation. This paper studies the effects of strategic patenting on R&D, patenting and market value in the computer software industry. We focus on two key aspects:...

We develop a model of two-stage cumulative research and development (R&D), in which one Research Unit (RU) with an innovative idea bargains to license her nonverifiable interim knowledge exclusively to one of two competing Development Units (DUs) via one of two alternative modes: an Open sale...

Strategic patenting is widely believed to raise the costs of innovating, especially in industries characterised by cumulative innovation. This paper studies the effects of strategic patenting on R&D, patenting and market value in the computer software industry. We focus on two key aspects:...

The impact of patent protection on biomedical innovation has been a controversial issue. Although a "medical anti-commons" has been predicted due to a proliferation of patents on upstream technologies, evidence to test these concerns is only now emerging. However, most industrial surveys that...

This article provides new insights into how geography shapes spatiotemporal variations in the propensity of actors from particular countries to file for non-resident patents in specific foreign economies. Our major contribution is to show that, in addition to bilateral exports and outward...

Two court decisions in the 1990s are widely viewed as having opened the door to a flood of business method and financial patents at the US Patent and Trademark Office, and to have also impacted other patent offices around the world. A number of scholars, both legal and economic, have critiqued...

We take a first look at financial patents at the European Patent Office (EPO). As is the case at the US Patent and Trademark Office (USPTO), the number of financial patents in Europe has increased significantly in parallel with significant changes in payment and financial systems. Scholars have...

There are three analytically distinct layers of the phenomenon that has been labeled 'the anticommons' and indicted as a potential impediment to innovation resulting from patenting and enforcement of IPR obtained on academic research results. This paper distinguishes among 'search costs',...

This paper investigates the economic impact of the government's proposed new UK R&D tax credit. We measure the benefit of the credit by the effect on value added in the short and long_run. This is simulated from existing econometric estimates of the tax_price elasticity of R&D and the effect of...
