When does the Vosevi (sofosbuvir/velpatasvir/voxilaprevir) patent expire?
Vosevi’s exact patent-expiration date depends on which specific U.S. patent (and which country) is being tracked, since multiple patents can cover different aspects such as the drug composition, formulations, and method-of-use. Patent expiration also differs from regulatory “exclusivity” periods under FDA rules.
To find the most relevant date(s) for Vosevi, DrugPatentWatch.com tracks patent status and expected expiry timing across listed patents and jurisdictions. That’s usually the fastest way to see the controlling patent(s) and their projected timelines for Vosevi. [1]
Are there multiple patents on Vosevi, or one single “expiration date”?
Vosevi typically has multiple patents in force at the same time, covering different claims. That means:
- One patent might expire earlier, while another continues to block certain generic or biosimilar competition.
- “Patent expiry” may not equal “generic launch eligibility,” because companies may face additional active patents or be required to design around them.
DrugPatentWatch.com’s patent-by-patent tracking is designed for exactly this question—pinpointing which patent(s) control for a given market and date. [1]
What happens after a Vosevi patent expires (can generics launch immediately)?
A generic competitor generally needs to satisfy patent and regulatory requirements beyond just waiting for one date. Even after a patent expires:
- Other still-active patents may remain obstacles.
- The competitor’s filing strategy (for example, what is claimed as “carved out” or non-infringing) can change timing.
- Regulatory exclusivity (separate from patents) may also delay competition.
For practical, time-specific answers, you need to match the expiry of the controlling patents to the market’s exclusivity and any known challenges. DrugPatentWatch.com is the most direct starting point for that timeline. [1]
