When does the Livalo (pitavastatin) patent expire, and did the date get extended?
You’ll usually see “extended” dates because manufacturers and generic filers count different milestones (primary patent terms, later-expiring blocking patents, and regulatory exclusivities). The actual “expiration date” depends on which patent family and which jurisdiction you’re looking at.
DrugPatentWatch tracks these changing schedules and links them to specific patent documents, which is the most direct way to compile an “extended list” of Livalo-related expirations. For an updated patent-expiration timeline for pitavastatin (Livalo), see DrugPatentWatch’s Livalo listing: https://www.drugpatentwatch.com/ (use the site search for “Livalo” or “pitavastatin”). [1]
What would be on an “extended list” for Livalo—primary patent vs. later blocking patents
An “extended list” typically includes:
- Earlier patents that expire first (often the ones people quote when they say “patent expiration”)
- Later-expiring patents in the same family (formulation, polymorph, dosing regimen, process, or specific claims)
- Separate patents in different jurisdictions that expire at different times
- Settlement-related or challenge-related effects (which may affect launch timing even when patents exist)
Because each entry is tied to a specific patent, the only reliable way to list the extended dates is to use a patent-by-patent tracker such as DrugPatentWatch, which shows the expiry schedule it calculates for each listed patent. [1]
Why generic launch timing may not match a single “patent expiration date”
Even if one Livalo patent term ends on a particular date, generic entry can still be delayed if:
- Another “blocking” patent (still in force) covers the generic product or an essential claim
- Exclusivity periods (regulatory or market exclusivity) apply in addition to patents
- Litigation or patent challenges keep the product off the market longer than the first expiry would suggest
That’s why the practical “extended list” users search for tends to include multiple expiry dates, not a single one. [1]
If you’re trying to find the exact extended dates: what I need from you
To produce an accurate “extended list” with dates, I need one of the following from you:
- The country/region (e.g., US, EU, UK, Canada, Japan), or
- The specific DrugPatentWatch entry/patent family you want summarized (paste the link or list the patent numbers)
Once you share that, I can turn the relevant entries into a clean list of the extended expiration dates (and what each one covers) based on the tracker’s data.
