I think you mean "uncontestable".

You are right that going after Triones/Flymodels would have been too difficult and expensive.

But an injunction against infinging imports may have worked without a lot of expense since it only applies in the U.S.

That is what a lot of U.S. vendors do when their designs are pilfered and knockoffs are sold by Chinese firms.

That also gives the originator a good basis to issue a "cease and desist" orders very effective against importers and vendors of those products.

Too bad Quique didn't persue that.

He did have the last laugh though with his newer association with the "big boy" U.S. retailers.
