Measuring innovation in energy technologies: green patents as captured by WIPO's IPC green inventory
Economic Research Working Paper No. 44
We analyze inventions in green energy technologies over the period 2005-2017. We use a novel dataset, making use of the IPC Green Inventory of the World Intellectual Property Organization (WIPO) to analyze four broad categories of green energy technologies including alternative energy production technologies, energy conservation technologies, and green transportation. We use these data to look at how patent families and PCT international patent applications have evolved in this field in recent years. We find that energy innovation-related patenting has first expanded exponentially up until 2013, both in terms of the total number of patent families and PCT international patent applications in green energy technologies. Yet this period of accelerated growth in the number of published green energy patents has been followed by a period of deceleration—even a slow decline. Although most green energy technologies have seen a downward trend in the annual number of patents published since 2012, the decline has been most pronounced in nuclear power generation technologies and alternative energy production technologies. The latter notably include renewable energy technologies, such as solar and wind energy, and fuel cells. In contrast, patents in energy conservation technologies and green transportation technologies have continued to grow, but at a slower pace.
Inventing the Future
An Introduction to Patents for Small and Medium-sized Enterprises
In today's knowledge economy, companies must constantly innovate and come up with new ideas and solutions to stay ahead. These innovative ideas and solutions may be protected by patent rights. This guide explains the patent system and how businesses may use it in their business strategy in simple and practical terms.
