What is US patent 10,335,462 about (semaglutide)?
US Patent 10,335,462 is a U.S. patent related to semaglutide—an active ingredient in branded GLP-1–based therapies. Public patent records typically describe the protected subject matter as method(s) of use and/or formulations tied to semaglutide, rather than covering the molecule itself in every case. Patent scope matters because different patents around semaglutide can cover different aspects (composition, dosing, specific regimens, manufacturing, or specific delivery approaches).
Because patent numbering alone doesn’t tell you which element is claimed, the most direct next step is to check the patent’s claim set (independent claims and claim wording), since that is what determines whether a competitor’s product or label use would fall inside or outside the protected scope.
How to find the exact semaglutide claims in 10,335,462
To verify what US 10,335,462 protects, look at these parts of the document:
- The “Claims” section: the independent claims show the core legal boundaries.
- The “Abstract” and “Summary”: helpful for plain-English context, but not what controls infringement.
- Any “Examples” and “Description”: often show preferred embodiments, which may influence interpretation of claim terms.
- Any “Priority” and “Filing/Publication” dates: important for term and for understanding which earlier inventions the patent claims.
If you share the assignee name (or a link to the patent page you’re looking at), I can help map what the claims likely cover in plain language.
When does the patent expire (and does it block generic semaglutide)?
Patent expiration depends on:
- The filing date and the patent term rules for that filing (generally 20 years from the earliest effective non-provisional filing date, subject to adjustments).
- Any patent term adjustment (P.T.A.) granted by the U.S. Patent Office.
- Whether exclusivity (FDA non-patent exclusivity) also applies for the specific product and indication.
Even if US 10,335,462 is still within its enforceable term, whether it blocks a generic depends on:
- The generic’s formulation and route (e.g., injection vs oral), dosing regimen, and whether it practices the claimed method(s).
- Whether the generic is attempting to design around the specific claim language.
- Whether the patent is challenged (e.g., invalidity or non-infringement arguments in litigation).

Are there related patents that matter more than 10,335,462?
Semaglutide products typically sit inside a web of patents rather than a single blocking patent. For example, different patents can cover:
- Specific device/delivery details for injections
- Specific dosing schedules or patient populations
- Formulation or stabilization approaches
- Manufacturing processes
- Methods of treating particular diseases or using specific dose ranges
So a generic or biosimilar entrant may be blocked by one patent while potentially able to design around another, depending on how their product maps to the claim scope.
Who would be affected by US 10,335,462 (and how do disputes usually play out)?
When patents like this are asserted against competitors, the usual dispute centers on:
- Claim construction (what the words mean)
- Infringement (does the competitor’s product/practice fall within the claims)
- Validity (prior art, obviousness, indefiniteness, written description issues, etc.)
If you tell me which semaglutide product you mean (Ozempic, Rybelsus, Wegovy) and the competitor/generic you’re interested in, the likely relevance of US 10,335,462 can be assessed in context of that product’s labeled use and formulation.
