Compared with Taiwan and Korea, China has been registering relatively few solar PV patents at the USPTO, and a low level of intra-national knowledge flow (only 2.8% or 14 local-citations out of a total number of 488 backward citations).
Given the relatively mature state of solar technology and the number of companies operating and seeking to operate in the sector, it is not surprising that there has been an increase in litigation in recent years concerning the patents underlying solar technologies. One of the most significant disputes to date has been between SolarEdge and Huawei.
Companies involved in this increased uptake of solar power need to be aware of patents not just where they are ultimately used, but also where they manufacture and assemble panels and their components. This is reflected in patenting trends.
The patents relate to technology for the improvement of the efficiency of solar cells. The first instance decision concerning the German designation of EP 22 20 689 B1, before Regional Court of Dusseldorf, ruled in Hanwha Q-Cells' favour.
The solar photovoltaic industry is of particular interest in that it is poised between exploitation of first generation (crystalline silicon technologies) and new thin film and organic compound technologies, thus providing distinct sources of knowledge flow as measured by patent citations and linkage.
With the awareness of global warming and the rise of fossil fuel energy prices since the late 1990s, the patenting rate concerning green technologies surged in the 2000s ( Bauer and Neuhaus, 2008, Glachant et al., 2009 ). Solar PV is one of the rapid growth alternative-energy technologies to be adopted ( Mowery et al., 2010 ).
