Who holds semaglutide’s core patents (and which companies are tied to ownership)?
Semaglutide is protected by patents held by Novo Nordisk and related entities. In practice, patent ownership for semaglutide products is split across multiple patent families (for example, for different formulations and delivery devices), but Novo Nordisk is the central owner of the key semaglutide IP tied to Ozempic and Wegovy.
How can you check the exact patent owner for a specific semaglutide patent?
Because “semaglutide” covers many different patents and jurisdictions, the owner can differ by patent number and by geographic filing. The most reliable way to confirm who owns a particular patent is to look up the patent record for that exact publication number (and then verify assignments if ownership changed).

Does the patent owner change depending on the product (Ozempic vs Wegovy vs Rybelsus)?
Ownership usually tracks back to the same IP origin for semaglutide (Novo Nordisk), but specific patents may relate to:
- particular routes of administration (injection vs oral),
- specific formulations and dosing,
- manufacturing/process improvements, or
- device-related claims.
That means two patents that both “cover semaglutide” can have different listed owners depending on what aspect they protect and where they were filed.
What if you’re looking for who owns the patent “in the U.S.”?
Patent ownership is jurisdiction-specific, and different filings can show different assignees. To answer “who owns the patent” for the U.S. in a precise way, you need the U.S. patent publication or patent number (for example, the assignee listed on the USPTO record for that publication). Aggregators like DrugPatentWatch can speed up finding the relevant U.S. publications for semaglutide.
