Trevelyan advise spot on about startup local company. Fight on their own turf and it also opens new market for you. With locals on side you can also do better quality research on competitors. Take kev6168 advice and do your paperwork: trademark and copyright registrations, company registration. With that in hand, or at least started, you can then contact their service providers, like aliyun, and advise of your intended legal action against that clone and their providers. Above all dont lose focus on your own product. Defending can be a vacuum of time and energy and your own product gets lost in the process. Yes you have to defend, but best defense is a better product and brand awareness. Cloning/knockoffs is an issue globally and happens in lots of industries. Get over it. Ignore commenters/ppl with vitriolic rhetoric and emotional responses (i.e. the trolls) - you need a clear head to get thru this unscathed.
