Studies of innovation have focused on the effects of patent laws on the number of innovations but ignored effects on the direction of technological change. This paper introduces a new data set of close to fifteen thousand innovations at the Crystal Palace World's Fair in 1851 and at the Centennial Exhibition in 1876 to examine the effects of patent laws on the direction of innovation. The paper tests the following argument: if innovative activity is motivated by expected profits, and if the effectiveness of patent protection varies across industries, then innovation in countries without patent laws should focus on industries where alternative mechanisms to protect intellectual property are effective. Analyses of exhibition data for twelve countries in 1851 and ten countries in 1876 indicate that inventors in countries without patent laws focus on a small set of industries where patents were less important, while innovation in countries with patent laws appears to be much more diversified. These findings suggest that patents help to determine the direction of technical change and that the adoption of patent laws in countries without such laws may alter existing patterns of comparative advantage across countries.

This paper introduces a new internationally comparable data set that permits an empirical investigation of the effects of patent law on innovation. The data have been constructed from the catalogues of two 19th century world fairs: the Crystal Palace Exhibition in London, 1851, and the Centennial Exhibition in Philadelphia, 1876. They include innovations that were not patented, as well as those that were, and innovations from countries both with and without patent laws. I find no evidence that patent laws increased levels of innovative activity but strong evidence that patent systems influenced the distribution of innovative activity across industries. Inventors in countries without patent laws concentrated in industries where secrecy was effective relative to patents, e.g., food processing and scientific instruments. These results suggest that introducing strong and effective patent laws in countries without patents may have stronger effects on changing the direction of innovative activity than on raising the number of innovations

Previous studies have tended to focus on theeffect that patent laws have on number of innovations, ignoring the effect thatpatent laws have on technological change. Here, a data set of 15,000innovations at two World's Fairs--the London Crystal Palace Exhibition in 1851and the Philadelphia Centennial Exhibition in 1876--is used to examine theeffects of patent laws on technological change. Results indicate that patent laws directly influence innovative activity. Alack of patent laws in nineteenth-century Britain led inventors to focus onindustries for which secrecy was an effective alternative to protection by thelaw. Thus, inventors avoided innovations in the manufacturing and machineryindustries. The decision by the United States to adopt patent laws at the beginning ofthe nineteenth century may have played an important role in encouragingAmerican inventors to focus on the manufacturing and machinery industries,pushing technological innovation. The same positive effect may be observed fordeveloping countries today if technologies are encouraged that differ fromthose invented in developed countries. (LKB).

Patents as an Incentive for Innovation Edited by Rafal Sikorski & Zaneta Zemla-Pacud Patents are a reward for human inventiveness. A well-functioning patent system must provide incentives for innovation, safeguard dynamic competition and protect the public interest – a balancing act fraught with difficulty in the ‘connected’ global world. This ground-breaking book is the first to deeply analyse how patent law today performs its function of stimulating innovation in the crucial sectors of healthcare, agriculture, artificial intelligence and communications technology. Patent specialists, practitioners and scholars from various jurisdictions thoroughly describe how patent rights can be deployed to incentivize investments in researching and developing socially critical innovations without sacrificing the public’s interest in sharing the benefits that are produced. Among the emerging issues of patent rights investigated are the following: protectability and morality of according private rights over material derived from the human body; licensing on fair, reasonable and non-discriminatory (FRAND) terms; the supplementary protection certificate (SPC) manufacturing waiver; patent eligibility of artificial intelligence-related inventions; excessive enforcement of patents by patent assertion entities; enforcement of second medical use innovations; the so-called farmer’s privilege, the farm-save seed exemption, and breeders’ rights; international trade regulations and their influence on patent systems; human enhancement technologies and the consequences of patenting them; specifics of patent protection for biologic medicines; challenges posed by artificial intelligence for the disclosure requirement in patent law; and standard essential patent licensing, particularly in the context of the 5G standard. Perspectives taken into consideration by the authors include protectability criteria, length and scope of the granted protection, mechanisms for dealing with the friction between generalized application and specialized concerns, and rights enforcement. These aspects are analysed on the domestic, international and global levels. The COVID-19 pandemic has highlighted the urgent need to strike the right balance between innovation and access in healthcare and other technologies, a need rooted in patent law. Because the problems discussed – and solutions offered – in this collection of expert essays are of tremendous practical and cultural significance, the book will be of immeasurable value to practitioners, policymakers and researchers in patent law and other fields of intellectual property law.

What is the optimal system of intellectual property rights to encourage innovation? Empirical evidence from economic history can help to inform important policy questions that have been difficult to answer with modern data: 1) Does the existence of strong patent laws encourage innovation? And 2) May patent laws influence the direction - as opposed to the rate - of technical change? Economic history can also help to shed light on the effectiveness of policy tools that are intended to address problems with the current patent system: 3) How do patent pools, as a mechanism to mitigate litigation risks, influence the creation of new technologies? 4) Will compulsory licensing, as a mechanism to improve access to essential innovations in developing countries, discourage innovation in the developing countries? This essay summarizes results of existing research and highlights promising areas for future research.
