Do hydrogen-producing cars in China have to pay patent fees?

As for the patents of hydrogen energy, at present, 90% of the patents of hydrogen energy vehicles in the world are in the hands of Japanese companies. Enterprises in other countries have to pay a large patent fee to use it, but other car companies will definitely not do it. The existence of patent problems has led many car companies to turn to the development of pure electric vehicles. At present, major car companies are waiting for the patent of Japanese companies to expire. Nowadays, many countries are adopting the way of developing pure electric vehicles, supplemented by hydrogen energy vehicles. As long as the patent protection period expires, they should choose to develop vigorously.

Compared with pure electric vehicles, hydrogen energy vehicles are more in line with the concept of new energy vehicles, and are better in environmental protection, battery life and use. But there are many problems at present, and it is hard to say whether they can be solved. Therefore, pure electric vehicles are a better choice at this stage.
