True, but its about their operations in the US, which are required to follow US laws. They still need a patent and copyright from the US government for their US operations.
This means their patent for the drug in the US system means they can prevent it from being available to US consumers as a generic.
Also, the issue of the cost is related to how our government isn’t allowed to negotiate drug costs like others are.
The drug is made by a foreign company that has a presence in the US. They have a US headquarters for their US business.
Local laws have more to do with the issues raised in the article than the origin country of the company making the drug.
That’s like saying T-Mobile is bound by German laws despite operating in the US because it is owned by Deutsche Telecom.
