We explore the tail of patented invention value distributions by using value estimates obtained directly from patent holders. The paper focuses on those full-term German patents of the application year 1977 which were held by West German and U.S. residents. The most valuable patents in our data...

The U.S. has been under pressure to abandon the unique first-to-invent feature of its patent law for awarding patents. The opposition to reform however argues that switch to a first-to-file rule, the international norm, will undermine innovation. We evaluate this argument in a dynamic stochastic...

This paper analyses the nature of knowledge spillovers from research and development (R&D) in the field of liquid crystal display technology by estimating the impact of inventors' changing organizational and collaborative affiliations on the probability of citations in US patents filed between...

We examine the implications of pre-grant publication (PP) of patent applications in the context of a cumulative innovation model. We show that pre-grant publication of patents lead to fewer applications and fewer inventions, but it raises the probability that new technologies will reach the...

This policy paper on science-industry technology transfer has four emphases: the rationale of recent changes in German science policy, the contribution of diverse transfer channels to economic development as well as the role of IPR in that context, the differences in the institutional framework...

The question of protecting intellectual property rights by academic inventors was never seriously contemplated until the introduction of the Bayh-Dole Act in 1980 in the US. The Act allowed universities to retain patent rights over inventions arising out of federally-funded research and to...

This paper develops a methodology to compare the quality of examination services in different patent offices. Quality is defined as the extent to which patent offices comply with their patentability conditions in a transparent way. The methodology consists of a two-layer analytical framework...

Intellectual property rights and competition policy are intimately related. In this paper I survey the economic literature analyzing the interaction between intellectual property law and competition law and how the boundary between these two policies is drawn in practice. Recognizing that...

We examine the implications of pre-grant publication (PP) of patent applications in the context of a cumulative innovation model. We show that pre-grant publication of patents lead to fewer applications and fewer inventions, but it raises the probability that new technologies will reach the...
