>There is something extremely simple Amazon could do about it. If you have a registered brand in the Brand Registry and don't sell the product wholesale - there could be one box to check for that.

This isn't going to work because companies will lie their pants off to prevent distribution. I've personally had false IP complaints from multiple billion dollar companies, which are submitted under penalty of perjury, and I know of other companies that do the same.

What you should do is buy up their entire stock (it's FBA, and seems like not a lot of stock) and file not as described complaints with notice@amazon and also cc seller performance, then return as wrong item.
