Qu Xiaohua, founder, chairman and CEO of Canadian Solar, said at the China Solar Storage Original Technology Forum held on February 27 that China's photovoltaic industry has entered the "dark forest" era, and patents have become a weapon for internal circulation. Qu Xiaohua introduced that in the past 24 years, Canadian Solar has accumulated more than 4,000 authorized patents. "We encounter several patent lawsuits initiated by foreign companies every year, and we have never lost a lawsuit." "We oppose photovoltaic companies to engage in malicious competition in the name of patent protection. Canadian Solar hereby promises that it will not, and will not, use litigation as the first means to resolve patent disputes." Qu Xiaohua emphasized. Previously, Trina Solar sued Canadian Solar for patent infringement and claimed more than 1 billion yuan. Canadian Solar has fought back head-on.
