Are green energy technology patents declining?

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.

When did energy innovation-related patenting expand?

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.

What percentage of patent applications are based on geothermal energy?

In 2019, they accounted for 28 percent of publications in the renewables sector. However, international patent applications relating to geothermal energy accounted for just 1.4 percent of those published in the sector. Source: Economics and Statistics Division, WIPO Another way to analyze patent trends is to look at where the patent comes from.

Are green energy patents accelerating or decelerating?

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.

How many patent applications relating to renewables are there?

Using this measure, the total number of patent applications relating to renewables, based on the filing year of the first listed application, increased from 10,463 in 2002 to a peak of 27,089 in 2011. In 2017 (the most recent year for which data is available) the number was 24,027. What can we deduce from all these figures?
