No need for a lawsuit. Cease and desist letter should be enough.
Of course, I may be completely wrong and Yamaha may not have an issue with it at all.
It has nothing to do with whether Yamaha has an issue with it, and everything to do with the fact that there would be no way to enforce any complaint against such a small-time Chinese manufacturer. A cease and desist letter would be laughed at, nothing more.
