That is essentially the status quo. The issue is not patents, it is that Iran does not have the technology to manufacture these drugs. Unlike copyright, patents are country-specific. If you register a patent in the US, it is not valid in Argentina. If you register a patent in Russia, you cannot sue people for infringement in the US. There are of course trade agreements and other treaties that make it possible to register a patent in one country and have it recognized in multiple others. But for the most part, you have to register a patent in every country you wish to enforce it. Since in general, US does not allow US companies to do business with Iran, none of these patents are registered or recognized in Iran. Iran is not even a signatory of international copyright treaties, let alone bilateral patent recognition treaties. In general, any IP produced outside of Iran is fair game in Iran and vice versa. The issue is not the laws, it is that the technology to make them is not available in Iran, and any attempt to purchase the technology is thwarted with the same sanctions regime.
