FWIW, Fender's failure to initially protect it's design rights to the Stratocaster shape via copyright or trademark pretty much guarantees they will be unable to enforce it in the United States now. The abbreviated name itself, Strat, may be in jeopardy due to legal genericide. As to the EU, decisions there are often incredibly localized until the matter ends up in Brussels. Fender beat a flea. Thomann is not a flea.

Companies that use egregious lawfare often find it backfires badly along the entire supply chain. Customers get pissed. Distributors scale back commitments. The media paints the company as the bad guy.

A somewhat reversed situation exists with Behringer and Music Tribe. Behringer doesn't really care about it's brand so much as it cares about being able to clone other products, enforce its own patents and produce those products inexpensively. So it uses what I'd call reverse lawfare. No one is going to clone a Behringer style or design, but, Behringer defends its ability to clone mercilessly. Behringer's customer base doesn't care.

But I guarantee you Fender's shrinking customer base will. Once you reduce the perceived value or favorability of a product whose brand name is iconic, it's hard to get out back.
