Patenting and US academic research in the 20th century: The world before and after Bayh-Dole

The dramatic growth of patenting and licensing of publicly funded research by American research universities in the closing quarter of the 20th century has stimulated some of the highest-profile debates in science and technology policy today. The issue of what aspects of academic research should be public - and what private - lies at the heart of each of these debates. The movement of academic scientists into commercialisation of discoveries and inventions has been extolled by some as a new model of academic research, one which facilitates economic and social returns from universities. At the same time, this trend has been criticised by others as representing a socially inefficient ‘privatisation’ of academic research and as a threat to the ethos of science itself. This paper places these debates in historical context, with a review of changes in American universities’ patenting policies, procedures and practices throughout the 20th century, an assessment of the logic underlying the passage of the Bayh-Dole Act of 1980, and an overview of its effects on economic returns from university research.     

Universities as partners in U.S. research joint ventures

This paper investigates the conditions when a research joint venture (RJV) will involve a university as a research partner. We hypothesize that larger RJVs are more likely to invite a university to join the venture as a research partner than smaller RJVs because larger ventures are less likely to expect substantial additional appropriability problems to result because of the addition of a university partner and because the larger ventures have both a lower marginal cost and a higher marginal value from university R&D contributions to the ventures’ innovative output. We test this hypothesis using data from the COoperative REsearch (CORE) database, and those data confirm the hypothesis.     

A tale of two literatures: Transaction costs and property rights in innovation outsourcing

This paper investigates the relative importance of property rights and transactions cost factors in driving the decision of firms to outsource innovation. Using data for over 8000 firms from the UK Community Innovation Survey, we find that property right factors dominate over transaction cost factors. Transaction cost variables are more important for process innovation, while property rights variables are more significant for firms involved in product innovation. In addition, we find that firms involved in process innovation have a higher probability of outsourcing innovation than firms involved in product innovation.     

Contests for cooperation—A new approach in German innovation policy

A new approach in German innovation policy organizes contests of proposals for developing innovation networks. Based on an overview of the different programs, we investigate the advantages and problems of such an approach. We find that this type of policy may have a relatively large impact and can, therefore, be regarded as a rather efficient instrument of innovation policy. Compared to conventional policies, administration of the program is a much more critical issue. The contest approach may stimulate learning effects on the side of the administration but may also require a high degree of flexibility. The main disadvantage is the additional time that is required for conducting the contest. As a distinct ‘picking the winner’ approach, the contest approach is not suited as a means for achieving a leveling-out of regional welfare.     

The value of innovation: The interaction of competition, R&D and IP

This paper analyses market valuations of UK companies using a new data set of their R&D and IP activities (1989-2002). In contrast to previous studies, the analysis is conducted at the sectoral-level, where the sectors are based on the technological classification originating from Pavitt [Pavitt, K., 1984. Sectoral patterns of technical change. Research Policy 13, 343-373]. The first main result is that the valuation of R&D varies substantially across these sectors. Another important result is that, on average, firms that receive only UK patents tend to have no significant market premium. In direct contrast, patenting through the European Patent Office does raise market value, as does the registration of trade marks in the UK for most sectors. To explore these variations the paper links competitive conditions with the market valuation of innovation. Using profit persistence as a measure of competitive pressure, we find that the sectors that are the most competitive have the lowest market valuation of R&D. Furthermore, within the most competitive sector (‘science based’ manufacturing), firms with larger market shares (an inverse indicator of competitive pressure) also have higher R&D valuations, as well as some positive return to UK patents. We conclude that this evidence supports Schumpeter by finding higher returns to innovation in less than fully competitive markets and contradicts Arrow [Arrow, K., 1962. Economic welfare and the allocation of resources for invention. In: Nelson, R. (Ed.), The Rate and Direction of Inventive Activity. Princeton University Press, Princeton], who argued that, with the existence of IP rights, competitive market structure provides higher incentives to innovate.     

中国木犀属小志

In the present paper a new species, Osmanthus gracilinervis Chia ex R. L. Lu, is described from Guangxi.  The new species is also distributed in Guangdong, Jiangxi, Zhejiang, Hunan and Sichuan.  Based on the analysis of a great deal of specimens, eight spe- cies, i.e. Osmanthus corymbosus H. W. Li, O. longispermus H. T. Chang, O. angustifolius H. T. Chang, O. triandrus H. T. Chang, O. longicarpus H. T. Chang, O. omeiensis Fang ex H. T. Chang, O. nanchuanensis H. T. Chang and 0. cylindricus H. T. Chang, are reduced as the synonyms of O. marginatus (Champ. ex Benth.)  Hemsl. var. marginatus. O. longissimus H. T. Chang and O. pachyphyllus H. T. Chang are respectively reduced to varieties of O. marginatus, i.e.O.  marginatus var. longissimus (H.T. Chang) R. L. Lu and var. pachy- phyllus (H. T.Chang) R. L. Lu.  And finally O. maximus H. T. Chang is treated in this paper as a synonym of O. matsumuranus Hayata.
