6 Frequently Asked Questions about “Patent issues for high-efficiency photovoltaic cells”
What are the patents for solar cells?
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.
Are solar technology patents being litigated?
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.
Does PV technology have a role in patenting?
The technical review of these patents has shown the global continuous efforts for improving PV technologies and addressing their technical challenges. Taken together, the results show that the PV technological system has been deeply connected with patenting activities since its emergence in the past century.
Are Hanwha Q-Cells and LONGi Solar infringements a problem?
Another separate, ongoing multi-jurisdictional dispute of note is between Hanwha Q-Cells and Longi Solar. In 2019, Hanwha Q-Cells launched infringement proceedings initially in the US and Germany against Longi and additional defendants REC and JinkoSolar. The patents relate to technology for the improvement of the efficiency of solar cells.
Do solar panels need patents?
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.
What is the relationship between the PV sector and patenting activities?
Besides its growing global trends, the significant relation between the PV sector and patenting activities can further be illustrated by two observations: The first is the numerous radical PV inventions that were initially filed in patents (e.g. Siemens reactor, HIT cells, and DSSC).
