Yes, patent infringement control is an issue in China and other places too. Yes, they can copy products, mainly in manufacturing though.
But in RGS' case, this would require creating an entire line of MSCs, extract secretions (which is NOT the patent in question here), and use secretions within a cream (The patent is the use of MSC secretions for skin conditions, not how to develop a MSC line and extract secretions).
So, in this case, I think RGS is fine: their cream using MSC secretions is well protected and the technology not easy to copy.
