When does semaglutide patent expire?

See the DrugPatentWatch profile for semaglutide

Short answer
The patents that cover Novo Nordisk’s semaglutide (the drug sold as Ozempic®, Rybelsus® and Wegovy®) are set to expire in the mid‑2030s. In the United States the core composition patents run to 2035‑2036, the formulation and route‑of‑administration patents run to 2037‑2038, and the method‑of‑treatment patents (e.g., obesity) expire in 2037‑2038 as well. In Europe the equivalent patents expire between 2035 and 2039, depending on the country.


What the numbers mean

Patent type Typical filing year Typical US expiry date Typical EU expiry date Notes
Core composition (semaglutide chemical structure) 2007‑2009 2035‑2036 2035‑2036 Covers the active molecule itself.
Formulation / delivery (e.g., subcutaneous depot) 2011‑2013 2037‑2038 2037‑2038 Protects the way the drug is made ready for patients.
Method of use (e.g., obesity treatment) 2016 2037‑2038 2037‑2038 Covers specific dosing regimens for obesity.
Early “seed” patents (pre‑clinical chemistry) 2004‑2005 2024‑2025 2024‑2025 These are now long expired and no longer relevant for generic entry.

Why the variation?
Patents in the U.S. expire 20 years from the filing date, but extensions (e.g., for regulatory review time) can add a few years. European patents expire 20 years from the filing date as well, but the exact expiry depends on the country’s patent office. The dates above are the most recent U.S. and EU patents that cover semaglutide’s composition, formulation and therapeutic use.


Bottom line

  • U.S. generic entry: Likely not until 2036–2038.
  • Europe: Generic entry could be possible from 2035–2038, depending on the country.

These dates are based on the current patent filings and do not account for any future legal challenges or new patents that Novo Nordisk might file. If you need a definitive answer for a specific jurisdiction or product line (e.g., Wegovy® vs. Ozempic®), let me know!

Summary

The provided assessment states the thyroid C-cell tumor/MTC boxed-warning–related contraindication and counseling content are supported by label sections 4 and 5.1, and that rodent thyroid C-cell tumor findings are supported by section 13.1. No contradictions to the supplied label excerpts are identified.

Accurate Statements

Label supports a dose- and treatment-duration-dependent increase in thyroid C-cell tumors in mice and rats, and it is unknown whether OZEMPIC causes thyroid C-cell tumors (including MTC) in humans (Section 5.1).
5.1 Risk of Thyroid C-Cell Tumors: rodent dose/duration-dependent increase; uncertainty in humans.
OZEMPIC is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2 (Section 4).
4 CONTRAINDICATIONS: contraindicated in patients with personal/family history of MTC or MEN 2.
The label instructs counseling patients about potential risk for MTC and that routine monitoring of serum calcitonin or thyroid ultrasound is of uncertain value (Section 5.1).
5.1: counsel regarding potential risk and notes uncertain value of routine monitoring; also describes further evaluation if elevated calcitonin or nodules are present.
Carcinogenesis study results in nonclinical toxicology show statistically significant increases in thyroid C-cell adenomas and numerical increases in carcinomas at clinically relevant exposures (Section 13.1).
13.1 Carcinogenesis/Mutagenesis: CD-1 mice and Sprague Dawley rats findings consistent with statement.

Unsupported Statements

“Boxed Warning ‘Risk of Thyroid C-Cell Tumors.’” (as a claim of boxed-warning presence).
The prompt indicates excerpts are consistent with the boxed warning, but the provided label excerpts do not explicitly show the boxed-warning text itself. Based on the supplied excerpts, contraindications and Warnings/Precautions 5.1 are verifiably supported, but the boxed-warning text is not directly quoted in the excerpt set.

Contradictions


Important Omissions

No evaluation is provided for any specific contraindication details beyond personal/family history of MTC and MEN 2 (e.g., the hypersensitivity contraindication).
Importance: Low

Safety Assessment

Potential Patient Risk: Low
The assessment concerns label alignment for thyroid C-cell tumor risk, and the key contraindication/counseling and tumor-risk statements are supported by the provided label excerpts. Only the explicit boxed-warning text is not directly evidenced in the quoted excerpts.

Regulatory Assessment

On Label Yes
Off-label Discussion No
Promotes Unapproved Use No
Hallucination Risk Low

Recommendation

Mostly Aligned

Primary Issue
Boxed-warning presence was not directly quoted/verified from the excerpt set.

Suggested Improvement
Quote or explicitly reference the boxed-warning text from the label (if available) to directly support the boxed-warning statement; optionally also include verification of the hypersensitivity contraindication if assessing contraindications more comprehensively.
