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...

This paper examines the evolution of national competition (antitrust) policies and enforcement approaches vis-à-vis intellectual property rights (IPRs) and associated anti-competitive practices in major jurisdictions over the past several decades. It focuses especially on the underlying process...

The objective of this paper is to show the necessity of reviving the debate on the economic justifications for patent protection. On the one hand, we see the need for the assessment of the overall welfare consequences of the existing systems of patent protection, and on the other hand, we...

We use an exogenous change in German Federal law to examine how entrepreneurial support and the ownership of patent rights influence academic entrepreneurship. In 2002, the German Federal Government enacted a major reform called Knowledge Creates Markets that set up new infrastructure to...

We study the incentives that governments have to protect intellectual property in a trading world economy. We consider a world economy with ongoing innovation in two countries that differ in market size, in their capacities for innovation and in their absolute and comparative advantage in...

The patent system makes organized markets in patents with transparent prices possible. Such prices are here investigated as “signals” for inventors and innovators alike ofv aluable “technology areas”, in an experimental study. They inform decisions of specialized “firms” on...

The question of how prices on patents rights should be determined in impersonal exchanges is examined in a laboratory environment. Dynamic gains from such organized trade with public prices are recorded. The experiment introduces a competitive market with impersonal exchange mechanisms and...

We consider a model of the innovative environment where there is a distinction between ideas for R&D investments and the investments themselves. We investigate the optimal reward policy and how it depends on whether ideas are scarce or obvious. By foregoing investment in a current idea, society...

The Innovation Act was introduced by the French government in 1999, with the aim of encouraging academic institutions to protect and commercialize their scientists’ inventions. We explore the effects of the Act on the distribution of Intellectual Property Rights (IPRs) over academic...
