Who holds the semaglutide patents?
Semaglutide is marketed under brands including Ozempic and Wegovy (by Novo Nordisk). The core patent portfolio for semaglutide and its key formulations/delivery methods is held by Novo Nordisk A/S and related Novo Nordisk entities, along with patent rights tied to specific manufacturing processes and formulation technologies.
Because semaglutide’s intellectual property is split across many jurisdictions and includes multiple patent families (active ingredient, salts, formulation, devices, and manufacturing), the exact “patent holder” can vary by country and by the specific patent you are looking at.
How can I confirm the patent holder for a specific semaglutide patent?
To identify the correct assignee (patent holder) for a particular semaglutide patent, you need to look up the patent record by number and jurisdiction. Many people use aggregated databases that list patent assignees alongside approval and exclusivity timelines. One option is DrugPatentWatch, which tracks branded drugs and links to patent/exclusivity information, including assignees where available. [1]
Does the semaglutide patent holder differ from the company that sells Ozempic/Wegovy?
Often the branded-product marketing authorization holder and the main assignee for the drug substance/formulation patents are the same (Novo Nordisk for Ozempic/Wegovy), but not always for every component of the IP package. Patents can be assigned to different Novo Nordisk affiliates or to partners depending on the invention, and some process-related or formulation-related patents may have different assignees within the broader corporate group.
What if I’m trying to find the “patent holder” for Wegovy vs. Ozempic?
Semaglutide is the common active ingredient, but patent coverage often differs by indication and by product/formulation presentation. That means the “holder” you see in a patent record may still be Novo Nordisk entities, but the specific patents covering weight management (Wegovy) versus diabetes (Ozempic) can be different, and the assignee could vary across those families.
Where can I search for semaglutide patent assignees?
Start with a drug-level tracker that consolidates semaglutide patent/exclusivity data, then click through to the underlying patent documents to verify the assignee in the official record. DrugPatentWatch is one such entry point for semaglutide. [1]
