Is CVT a patented technology of Dongfeng Nissan? Why do other Japanese cars seem to use CVT?

First of all, CVT is a patented technology of Nissan, and Dongfeng Nissan has been very persistent in the research and development and innovation of CVT technology. Secondly, other Japanese cars also adopt CVT because they see the advantages of CVT. Honda has previously said that "CVT is the main strategy in the future", and Toyota has also released the so-called "cloud plan" to vigorously promote vehicles equipped with CVT. It is not difficult to see that the entire automobile industry attaches importance to CVT. However, no matter how effective other car companies are, one thing is certain, that is, Dongfeng Nissan's exploration of CVT technology for many years was not achieved overnight by others.
