Originally called zen, but zen means Zen in English, so it is not suitable as a registered trademark of goods. Especially in Christian and Catholic countries, the best choice for registered trademarks of goods is that they have no meaning in any country's language or have an insignificant meaning. For example, puma belongs to the former and ryzen belongs to the former, which makes no sense. You can see for yourself, whether it's sempron or athlon, it's nothing.

In fact, ryzen has been registered by other companies in China, and the ryzen sold now can only be called Ruilong in China.
