Chinese will replicate you if you stand still long enough,there's no intellectual property concept there,seen it many times,been in a couple of Chinese factories where they churned out well known brand copies,typical example,less than 2 US dollars for a fenn copy,easy enough to order and stick up on the bay,not taking the moral high or low ground,just saying it's what some people do.
