Who owns everolimus (the drug) today?
Everolimus is sold under brands such as Afinitor (Novartis). Ownership of the drug in practice is tied to the company that holds the relevant marketing authorizations (and the rights that come with them) in each country, plus any patents/exclusivities that limit competition. Brand rights and generic/biosimilar permissions can differ by market and by product presentation.
Which companies hold everolimus’s key rights and brands?
Novartis is the main company associated with everolimus’s best-known brand, Afinitor, in many major markets. Other companies may hold rights for specific generic versions or for particular indications, depending on country-specific approvals and patent status.
Who owns the patents for everolimus—and when do they expire?
Patent ownership (and who owns which patent families) can differ across jurisdictions and over time. Whether a company “owns” everolimus exclusivity in a practical sense depends on which specific patent(s) are still in force for the specific use (indication) and country.

Can other companies make or sell everolimus if they do not “own” the original drug?
Yes. Even if one company owns the original brand and key patents, other manufacturers can sell everolimus once patents/exclusivities for their target product (presentation/strength and indication) expire or are cleared via generic pathways and regulatory approvals.
What if you mean “ownership” as in the company behind the maker?
If your question is about the corporate owner behind the brand (not patent assignees), the commonly cited origin/brand owner for everolimus is Novartis.
Quick clarification question
When you say “Everolimus ownership,” do you mean:
1) the brand owner (company selling Afinitor),
2) the patent assignee (who owns specific everolimus patents), or
3) who can currently sell generics in a specific country?
Answering that will let me narrow to the exact organization and jurisdiction.
