The Changing Geography of the International Diffusion of Technological Knowledge
Economic Research Working Paper No. 92
This paper examines the evolving geography of international technological knowledge diffusion over the last four decades using multiple patent-based indicators. We first review the main mechanisms through which knowledge diffuses across borders—including trade and global value chains, foreign direct investment, skilled migration, global science, and markets for technology—highlighting their complementarities and the role of domestic capabilities. We then provide new empirical evidence based on cross-border patent citations, technological trajectories defined by IPC recombinations, patent-to-science linkages, and international patent families. The results reveal persistent asymmetries, with a small group of advanced economies remaining central knowledge hubs, alongside the rising role of emerging countries, especially China. Science-based technologies diffuse farther and faster, while capability constraints continue to limit integration for many regions.

How Do New Technologies Diffuse?
Economic Research Working Paper No. 91
Technology diffusion is central to economic development. This paper examines diffusion patterns for 31 technologies for 139 countries over two centuries, extending existing databases to include recent digital technologies and renewable energy technologies. Using cross-country panel regressions, we find that while adoption lags have declined from 50 years (pre-1950) to 15 years (post-2000), adoption intensity in developing economies remains at 53% of advanced economy levels. We document diverging intensity for older technologies but emerging convergence for post-2000 technologies, suggesting digital innovations may reduce the technology gap. These findings inform policies aimed at accelerating technology diffusion to developing economies.
World Intellectual Property Report 2026: Technology on the Move - Executive Summary
This Executive Summary highlights the key findings of WIPO's flagship World Intellectual Property Report 2026.The World Intellectual Property Report 2026 reveals striking patterns in how technologies spread globally, with profound implications for economic development.
World Intellectual Property Report 2026: Technology on the Move
Pushing the world's technological frontier by inventing new and better technologies is a necessary condition for long-term growth. For new and better technologies to raise economic productivity, they need to be widely adopted and used in the economy. Technology diffusion is a central part of the innovation journey. This report explores how different technologies diffuse within and across economies globally and the role of innovation ecosystems to foster it.
Innovation Capabilities Outlook 2026
This inaugural edition presents groundbreaking analytical methodology using patents, trademarks, publications, and exports data to comprehensively map global capability networks and systematically examine strategic diversification pathways for worldwide innovation ecosystems. Innovation Capabilities Outlook 2026 establishes a global baseline for innovation ecosystem analysis.
The Future is Under the Glass: Digital Design Protection and Appropriation Strategy
Economic Research Working Paper No. 97
The paper examines how legal certainty shapes protection and appropriation of digital designs such as icons, animations, and layouts. Leveraging the 2012 Apple v. Samsung verdict as a decisive clarification of their protectability and enforceability, we analyze USPTO design patents from 2009–2015 using a matched difference-in-differences approach. We show that legal certainty reduces due diligence costs far more than monitoring costs. This asymmetry lowers the threshold for securing protection, leading to a 9 percent increase in digital design patents. At the same time, appropriation shifted away from licensing toward transfers, with the effect strongest in dense design spaces where monitoring costs remain high despite increased legal certainty. These findings extend transaction cost theory by showing that legal certainty unevenly reduces transaction costs, which in turn alters protection thresholds and shifts appropriation strategies. They also demonstrate how policy changes influence innovation when value is created “under the glass.”.
Patent Cooperation Treaty (PCT)
Regulations under the PCT (as in force from January 1, 2026)
The Patent Cooperation Treaty makes it possible to seek patent protection for an invention simultaneously in each of a large number of countries by filing an "international" patent application. Such an application may be filed by anyone who is a national or a resident of a Contracting State.
The Technological Potential of Innovation Ecosystems: An Inter-Dimensional Network Approach
Economic Research Working Paper No. 90
In developing countries' innovation activities, limited patenting suggests structural gaps that hinder technological progress. This paper investigates whether countries can leverage their scientific and productive capabilities to realize untapped technological potential. We analyze connections between trade, science, and technology across global innovation ecosystems and introduce an indicator to assess where countries are positioned to expand their technological capabilities. Our results show that the indicator predicts technological output growth, though growth slows when countries exceed their predicted potential, indicating diminishing returns. The indicator performs better in more complex ecosystems. These findings provide valuable insights for policymakers, offering a framework to address weaknesses in innovation ecosystems and foster balanced, sustainable technological development.
An International Guide to Patent Case Management for Judges
Produced with the support of the University of California at Berkeley School of Law and the Berkeley Judicial Institute, this Guide highlights the progress achieved in patent case management in 12 patent-heavy jurisdictions. The Guide offers an overview of the patent system in each jurisdiction, including the role of patent offices in evaluating and deciding on patent validity, and the judicial structures responsible for resolving patent disputes. Thereafter chapters are structured on the different stages of patent litigation in civil infringement cases. Readers can create their own custom guide by selecting any combination of jurisdictions and topics covered in the Guide.
