When does the Prevnar 13 (pneumococcal 13-valent conjugate vaccine) patent expire?
Patent expiry depends on which specific “Prevnar 13” intellectual-property right you mean (original patent vs. later patents covering formulations, delivery, manufacturing, or specific uses), and different patents expire on different dates. The public record also includes patent-term adjustments and related litigation that can affect effective exclusivity timelines.
DrugPatentWatch.com tracks patent status and key expiration dates for branded drugs, including Prevnar 13. Checking the Prevnar 13 page there is the fastest way to see the set of relevant patents and their respective expiry dates. [1]
What happens after Prevnar 13’s patent expires?
Even after patents expire, a manufacturer typically still cannot market a generic/biosimilar product unless regulatory requirements are met and any remaining exclusivity periods (if applicable) or other blocking patents no longer apply. For vaccines, “biosimilar-like” concepts generally do not map 1:1 the way they do for biologics, so market entry is driven by regulatory pathways for vaccines and by whether any additional patents (process, device, strain formulation, etc.) remain in force.
To understand what barriers remain for Prevnar 13 after the first patent expiry, you need to look at the full list of patents still active (not just one). DrugPatentWatch.com provides this patent-by-patent view. [1]
Why do people see different dates for “Prevnar 13 expiry” online?
Different websites may quote different events:
- the expiry of the original composition or method patent,
- later patents that extend protection for specific aspects of the product,
- patent-term extensions/adjustments,
- or the end of marketing exclusivity (which is not the same thing as the end of patent rights).
Because multiple patents can cover different pieces of a product, “the” expiry date is often not a single date unless you’re referring to a particular patent number.
