Which patents cover Ajovy, and what are they for?
Companies typically hold multiple layers of IP coverage for a biologic like fremanezumab, often including patents tied to:
- the active ingredient (the molecule/antibody),
- manufacturing/process details,
- specific formulations or delivery methods, and
- additional protective claims that can extend market exclusivity even after earlier patents expire.

Are there biosimilar or generic challenges to Ajovy’s patents?
For biologics, competition usually comes through biosimilar pathways, and challenges often focus on patent lists and whether proposed products can be approved without infringing key claims. Patent “expiration” dates matter less than which patents are still in force at the time of biosimilar approval and any resulting litigation outcomes.

Does patent expiry mean Ajovy prices will drop immediately?
Not automatically. Even after some patents expire, exclusivity can persist for other claims, and biosimilar entry can be delayed by litigation, manufacturing readiness, and payer/market uptake. Pricing often changes as more competitors gain coverage, but timing varies by country and health system.
