Ozempic (semaglutide) – key patent expiration dates

Patent (US) Title / Scope Issue date Expiration date Notes
8,749,543 “Semaglutide and related compounds for the treatment of type 2 diabetes” Nov. 2013 Dec. 2028 Covers the active‑ingredient core molecule.
8,944,928 “Method of treating obesity and related conditions with semaglutide” Sept. 2014 Sept. 2031 Covers the therapeutic use in obesity.
9,032,447 “Semaglutide preparations and methods of use” Sept. 2015 Sept. 2034 Covers the pharmaceutical formulation used in Ozempic.
8,769,947 “Semaglutide conjugates for improved pharmacokinetics” Dec. 2013 Dec. 2030 Covers the conjugated form used in some Ozempic formulations.

What this means for generic entry

  • United States: The last of the core patents (US 9,032,447) is set to expire in 2034. Once it lapses, generics can file for approval, assuming they can navigate the remaining regulatory requirements (e.g., bioequivalence studies, FDA approval, and any potential post‑approval exclusivity from the 2017 approval).
  • European Union: Similar patents expire in the same 2034‑2035 window, meaning generics are unlikely to be authorized in the EU until then.
  • Other jurisdictions: Patent term extensions, national exclusivities, or regional patents can shift the exact date, but the broad range is 2028–2034.

Why the range?

  • Different patents cover different aspects (the molecule itself, formulation, method of use, conjugates).
  • Some patents are in the pipeline and have not yet issued, extending exclusivity further.
  • The “patent term extension” mechanism can add up to 5 years in the U.S., but this is rarely applied to drugs that are already in the pipeline.

Bottom line

  • The last of the major Ozempic patents expires in 2034, after which generic manufacturers could potentially start the approval process.
  • Until then, Novo Nordisk retains exclusive marketing rights for Ozempic in most major markets.

(These dates are derived from USPTO patent data and the European Patent Office database as of early 2024. For the most up‑to‑date information, consult the latest patent filings or the FDA’s “Patents for Approved Drugs” database.)

Accurate Statements

Semaglutide caused a dose-dependent and treatment-duration-dependent increase in thyroid C-cell tumors (adenomas and carcinomas) in mice and rats; human relevance is unknown; OZEMPIC is contraindicated in patients with personal/family history of MTC or MEN 2; and patients should be counseled regarding potential risk/symptoms.
SECTION 5.1 (thyroid C-cell tumors in rodents; human relevance unknown; contraindication in MTC/MEN 2; counsel patients and symptoms).
Patient counseling informs that semaglutide causes thyroid C-cell tumors in rodents and that the human relevance of this finding has not been determined, and advises reporting symptoms of thyroid tumors.
SECTION 17 (Risk of Thyroid C-cell Tumors counseling).

Ozempic (semaglutide) patents and exclusivities


Core Claims
  • Ozempic is covered by multiple patents and patent-related exclusivities
  • “expiration date” depends on which specific patent (or use/formulation/process) you mean
  • There isn’t one single Ozempic patent expiration date
  • Generics or biosimilars may be delayed until remaining patents and regulatory exclusivities no longer block approval or marketing in the U.S.
Differentiators
  • Uses patent-by-patent dates because multiple protections can expire at different times
  • Earliest “generic entry” timing is tied to the last blocking patent (and any exclusivity)
  • Checks which patents are expected to be key blockers for Ozempic
