Well, I don't think there are really any cups out there that are substantially identical to the yeti cups any more. I don't do many rtics but their lids are now different size. Both the JDS cups have changed and Ozark trails changed last year. I think that yeti will waste more trying to prosecute this than they can get. I was in restaurant supply manufacturing for a long time, it was known fact, design a new line of dinnerware, and in a year it would be copied..... Even if poor seller. Just fact of life. And they didn't try and put copyright or patent on their cups.
