Niveau: Supérieur, Doctorat, Bac+8
Solar - 1 Invention and transfer of solar technologies, 1978 – 2003 This note is a technical annex to a general report on Invention and Transfer of Climate Change Mitigation Technologies on a Global Scale: A Study Drawing on Patent Data. The complete report can be downloaded at: The note describes the invention and transfer of solar technologies in the world between 1978 and 2003. These technologies include solar photovoltaics (PV), concentrating solar power (CSP) and solar heat (heating & cooling). The first section focuses on the number of inventions and gives descriptive statistics on the main inventor countries. Section 2 deals specifically with the international flows of technologies and investigates which countries are the main exporters and importers of solar technology. Key points • The number of inventions decreased between 1978 and 1988, and increased between 1988 and 2003 at an average annual rate of 5.3%, without returning to the level of 1978. 895 inventions sought legal protection in 2003, down from 1,191 in 1978. • During the 1998-2003 period, the main inventor country was Japan (42% of total inventions) followed by Germany and the USA (with respectively 17% and 11%). • The main recipient country is also Japan, with 28% of all patents filed between 1998 and 2003, followed by Germany and the USA.

Invention and transfer of solar technologies, 1978 – 2003 This note is a technical annex to a general report onInvention and Transfer of Climate Change Mitigation Technologies on a Global Scale: A Study Drawing on Patent Data. The complete report can be downloaded at: http://www.cerna.ensmp.fr/index.php?option=com_content&task=view&id=192&Itemid=288 The note describes the invention and transfer of solar technologies in the world between 1978 and 2003. These technologies include solar photovoltaics (PV), concentrating solar power (CSP) and solar heat (heating & cooling). The first section focuses on the number of inventions and gives descriptive statistics on the main inventor countries. Section 2 deals specifically with the international flows of technologies and investigates which countries are the main exporters and importers of solar technology. Key points The number of inventions decreased between 1978 and 1988, and increased between 1988 and 2003 at an average annual rate of 5.3%, without returning to the level of 1978. 895 inventions sought legal protection in 2003, down from 1,191 in 1978. During the 19982003 period, the main inventor country was Japan (42% of total inventions) followed by Germany and the USA (with respectively 17% and 11%). The main recipient country is also Japan, with 28% of all patents filed between 1998 and 2003, followed by Germany and the USA. Meanwhile, 7.3% of patents were filed in China and 2.4% in Korea. International technology transfer is slowly increasing. The share of exported inventions has risen from 12% in 1984 to 18% in 2003. Meanwhile, the average number of countries in which a given innovation is used has been stable around 1.6. Although they lag far behind developed countries, emerging economies have increased their production of inventions by 17.4% annually during the last period considered (19982003). China leads this group with 8% of the worldwide production of innovation during this timeperiod. These innovations are seldom exported, suggesting they are tailored to local needs.
