Anecdote: apparently going after Chinese knock-off companies is a gigantic PITA. I've worked with those who have tried going after them. File a complaint about company ACBD. A week later, company ABCD never existed, but company XYZ is operating at the same factory. Amazing!
Which could be said about so many such knockoffs; however, the issue of Chinese and other non-US counterfeiting is harder precisely because they're non-US, and operating in manners and areas where the legal system is not prone to caring about US regulations (for better or worse).
So whether you can safely ignore this depends largely on how easy it is for this body to successfully throw the book at you, and others' success in this area doesn't really mean anything unless you're able to operate in the same circumstances, which I doubt most of us are.
