This article is the second in our renewable energy patent tracker series. The first, published early March 2021, compared patent trends for renewable energy generation technology from 2016 to 2020 with data from the first two months of this year. Using the Y02 classification scheme developed by the EPO for labelling climate change mitigation technologies, we compared the number of publications in different renewable energy fields (solar PV, solar thermal, wind, geothermal, hydro and from the sea) and ranked the biggest patent filers in these areas. In this instalment, we update our statistics for this year, incorporating data from up until the 19th May, and extend our trend analysis over the ten years leading up to 2021.
Insights: filing trends
Those statistics are complimented by the release of the Patent Index 2020 – patent filing statistics at the European Patent Office (EPO). The annual Patent Index allows for both a general assessment of innovation, and a deeper analysis into filing trends within Europe.
As climate change and the energy transition drive fundamental shifts in technology, industry, investment and regulatory policy, innovation and technology have never played a more important role. In this article, we discuss how climate change and the energy transition are driving these shifts, the technologies needed to meet net-zero and how this is reflected by patent filings in renewable energy field. We gather the perspectives of leaders and decision makers in the fields of energy, technology, business and government, presenting at the recent CERAWeek 2021 conference.
