According to a comprehensive new study by the European Patent Office (EPO), Germany, France and the UK join Japan, the US and South Korea in leading the emerging green tech revolution, filing 80% of all patent applications in the field.
EPO Chief Benoît Battistelli said China, India and Brazil are catching up quickly and have ramped up their efforts in niche clean tech sectors. China is now the major player in the wind energy sector, despite having published very few patents in this industry until five years ago.
"In wind energy, China has gone from being nowhere five years ago to being the leading player globally. For India and Brazil, photovoltaic technology and hydropower are the major sources of patents," said Battistelli.
Political signal sparks green innovation
The study by the EPO, the UN Environment Programme, and the International Centre for Trade and Sustainable Development, reveals a surge in new patent applications in the clean energy sector following the Kyoto protocol.
Battistelli said political signals can help spur investment by industry in low-carbon technology, arguing that a future deal on climate mitigation could generate a new wave of innovation in the energy sector.
"The key message is that the policy and regulatory framework influences how businesses invest. In all environmental issues the market is decided by the regulatory framework. The market needs to be framed," he said.
Meanwhile, the Belgian presidency tabled a non-paper aimed at breaking the deadlock over proposals for a single EU-wide patent system.
The paper was discussed at the Competitiveness Council yesterday (30 September), where the majority of member states recognised the importance of an urgent solution and sided with the text drawn up by the European Commission at the end of June, reads a presidency statement. But a small minority of countries still had remarks concerning this text or formulated a counterproposal.
The EPO study, published yesterday (September 30), provides details of where green-industry patents are held and whether they are licensed. Battistelli says there is willingness in the industry to offer more flexible terms to low-income countries.
Technology transfer continues to be a key issue in climate talks and the EPO plans to take its study to the next round of negotiations in Cancun later this year. The data compiled as part of the study is available free online and will be updated daily.
"This kind of information has become central to climate negotiations where the role of patents is controversial – many people consider patents an obstacle to technology transfer. But until now, the discussion has not been based on hard data. This study will feed into the debate on climate change and technology transfer, said the EPO chief.
Battistelli said some see patents as a brake on the dissemination of innovations in the clean tech sector.
