When does semaglutide’s patent protection expire in the US?
The exact end date depends on which patent(s) you mean (for example, the original active-substance formulation vs. specific dosage forms, delivery devices, or later “life-cycle” patents such as new formulations). Those different patent families can expire in different years, and manufacturers may also have additional regulatory exclusivity that affects market entry even after a patent expires.
When does semaglutide’s patent protection expire in the EU?
EU patent expiry also depends on the specific patent(s) covering semaglutide and related product features (formulation, strength, manufacturing, delivery system). Even if one patent family expires earlier, other patents or supplementary protection tools can keep competitors off the market longer for specific products.
When does semaglutide’s patent protection expire in China?
China’s timeline varies by patent family and by how exclusivity and regulatory authorization interact with those patents. As with other regions, later-stage patents (new strengths or formulation/process improvements) can extend practical exclusivity beyond the first filing’s original window.
When does semaglutide’s patent protection expire in India?
India similarly has a mix of patent filings across active ingredient, formulation, processes, and device-related claims, so different patents can expire in different years. Market access also depends on patent status at the time generic/biosimilar makers seek approval and/or launch.

If you tell me the brand and form, I can narrow the answer to the right expiry dates
If you share which one you mean (Ozempic vs Wegovy vs oral semaglutide) and whether you want the earliest likely “first” patent expiry or the latest “last” relevant patent expiry, I can focus the timeline to the correct patent set (US/EU/China/India) using the same source.
