The patent waiver doesn't require any Congressional changes to US patent law or require the President to unilaterally overrule US patent laws. US patent law only covers patents in the US. The US and almost all other countries are in the World Trade Organization (WTO). The WTO has an agreement called TRIPS which covers IP requirements of member states. Part of the requirements of TRIPS is that most member states have to reciprocate patent rights for patents issued by other member states. The WTO can waive this requirement with a vote of the WTO General Council. This is what is being proposed and Biden has declared that the US now supports doing so. This is completely within his powers as President.
