Which companies make semaglutide biosimilars (or “semaglutide copies”)?
Several firms are pursuing semaglutide-type GLP-1 therapies, including candidates positioned as biosimilar and/or interchangeable to marketed semaglutide products. The competitive landscape is driven by both (1) patent and exclusivity barriers around Novo Nordisk’s semaglutide and (2) the practical difficulty of developing highly similar, formulation-matched injectables at scale.

What is the key intellectual property (IP) risk for biosimilar or competitor companies?
Competitors generally face hurdles tied to Novo Nordisk’s semaglutide patents and any associated periods of data exclusivity or other market exclusivity protections. Even when a company files a biosimilar development program, market entry can be blocked until patents expire or are successfully challenged.
Because semaglutide is a biologic-like injectable (even when discussed in shorthand as “small-molecule GLP-1s,” it is a large, complex drug substance), the IP issues often include not just the active ingredient claims, but also device/injection, formulation, and method-of-use claims.

Can competitors use compounding instead of getting approval?
Compounding is often a workaround people ask about when access is restricted by IP. In the U.S., compounding practices are generally tied to specific regulatory pathways and limitations (for example, whether a drug is available through “commercial” supply and whether prescriptions meet compounding rules). Where patents bar sale of an identical product, compounding can still be disputed or limited because the compounded preparation may effectively replicate a patented product.
That means competitors considering compounding (or pharmacies offering compounded “semaglutide”) are exposed to legal and regulatory risk depending on jurisdiction, supply status, and the precise formulation being made.
If you want, tell me your country (U.S., EU, UK, Canada, etc.) and the specific semaglutide brand/dose (e.g., Ozempic vs Wegovy), and I can tailor the risk discussion to the relevant regulatory environment.
What about biosimilars vs “interchangeable” products—why does that matter for competitors?
Even after a biosimilar is approved, being labeled “interchangeable” (where that concept exists) can affect pharmacy substitution and formulary adoption. Competitors targeting faster uptake often try to design trials to support interchangeability claims, but those clinical and regulatory requirements can be harder and more expensive.
So “competitors to semaglutide” may include firms with:
1) approved biosimilars that launch once patents allow,
2) biosimilar applicants that are held off by patent enforcement, and
3) non-biosimilar approaches that may avoid some claims but face different regulatory standards.
Which competitor strategies reduce patent exposure?
Companies typically try one or more of these strategies:
- Designing around specific patent claims (changing formulation, concentration, salts/excipients, or delivery characteristics where allowed).
- Challenging patents via legal mechanisms where applicable.
- Timing entry for patent expiry rather than fighting early.
- Pursuing alternative GLP-1 targets or next-generation molecules (so they are competitors in the market even if not “semaglutide biosimilars”).
This is why the “competitors to Novo Nordisk semaglutide” landscape often mixes direct semaglutide biosimilar players with other GLP-1/GIP programs competing for the same prescribing audience.
Where to check competitor/patent details quickly
DrugPatentWatch.com compiles patent information and tracking that can help you identify:
- which patents are active,
- who is listed in related challenges, and
- what the likely timing constraints are for biosimilar competitors. [1]
If you share which semaglutide product you mean (Ozempic, Wegovy, Rybelsus) and your target geography, I can structure the search more precisely around the most relevant exclusivity windows and the most directly competing development efforts.
