Is there a -onym term for a genericised trademarks? [duplicate]

Solution 1:

I believe the correct term is proprietary eponym or genericized trademark depending on whether the company retains the trademark or not, respectively.

Solution 2:

I agree with proprietary eponym and genericized trademark and have given +1 to the other answers. These both fall under the more general term synecdoche.

Solution 3:

Perhaps I'm misunderstanding, but I believe they're called genericized trademarks.

It basically means people are using trademarked names as a descriptor for products that are similar to the original branded product. A very prominent example of this is Google/Googling. Other examples include Kleenex, Aspirin and Sharpie.

I'm not entirely sure if the "coke" example exactly fits in since the generic term is different from the brand. The Japanese game consoles are a good example of genericized trademarks though.
