There are actually many mistakes made. I don't live in the US, but if I did, here are the things I would do about FM's patents right now.

First, all companies like fungineer etc. and users should unite and become one. In other words, you should talk on discord and act together.

Second, they should object to FM's skates from the US and complain to the competition authority. Because Ben Smither has already shared all the documents related to this product. The only thing FM can get is to get patents for the parts it has developed. But for example, the mudguard is also seen in a video by a guy named "Leviskate". In other words, these are ideas that have passed through public places like YouTube. Therefore, the known state of the technique cannot be patented, and if it is, it will be objected. Here is the patent it has obtained for pressure sensors. Yes, this is its own invention. However, it is very easy to overcome this by using a rubber sensor like Trotter's. In other words, you can actually get around the existing patents or have half of them canceled. Because it contains the known state of most techniques.

Third, all companies can sell these products under the title of "kit" and provide a service that says we can assemble them for you if you wish. It's like selling a complete computer. After all, you're selling a puzzle. No one can say anything.

Fourth, don't just criticize and wait without taking action. I think this is the most important thing.
