No its not that simple. First there is nothing out that would allow you to reverse engineer the chip other than the chip itself. The information floating around the internet is Mere PR, nothing too descriptive.
Ok Lets say China Co. 3000 manages to reverse engineer the chip. They still need to produce it somewhere, some foundry. There really is not too much labor involved in producing these chips when you think of the volume. The majority is setting up the tooling and R&D (we all know how much that costs).
Now lets say they could produce it, and get it into some major OEMs product. Now when that product is shipped to here or Europe and MRVL finds out there is an infringing component. That entire product gets seized or banned until it no longer infringes... AKA QCOM/BRCM.
This changes rapidly if instead of Major OEM suppliers like DELL, HPQ, Toshiba ... you mean knockoffs that are just selling the AC/DC adaptor under no name brands. Then its really hard to sue when you are only talking a few hundred thousand units here and there...
