What patents cover ranolazine, and who owns them?
Ranolazine (the active ingredient in the angina drug Ranexa) is protected by a long series of intellectual-property claims, typically including composition-of-matter and use/patent-life-extension filings. Those protections are owned and managed by the brand’s patent holder(s) and their assignees, but the exact list of “Ranolazine patents” depends on the country and the specific claim family (original drug, specific dosing/use claims, and any later refinements).
When does ranolazine’s patent protection expire?
Patent expiry depends on:
- the jurisdiction (US, EP, UK, etc.),
- whether you mean “primary” patent expiry vs. any later patent term adjustments or supplementary protection (if applicable in that region),
- whether you mean the earliest patent expiration that blocks generic entry vs. later patents that could extend exclusivity.
Because “ranolazine paten” doesn’t specify a country, the exact expiry date can’t be stated reliably without the jurisdiction and (ideally) a reference to the patent number or product label.
Can generics enter before all ranolazine patents expire?
Generics usually launch only when they can:
- clear the patent thicket via successful challenge (for example, in the US via an Abbreviated New Drug Application pathway with paragraph certifications), or
- avoid infringement of active patents through design-around or timing.
This means a generic might be delayed by later-expiring patents even if some earlier patents have expired.
How to look up the exact ranolazine patent details you need
If you tell me the country (e.g., US) and whether you want:
- the first filing,
- the latest expiry,
- or a specific patent number,
I can map out the relevant patent families and their expiration timelines. To make the search precise, you can also share one of these:
- drug trade name (Ranexa is common),
- the market you care about (US/EU/etc.),
- any patent number you’ve seen.
Quick clarification so I can give a specific answer
Which one do you mean by “Ranolazine paten”?
1) Patent expiry date for ranolazine in the US or EU
2) A list of the main ranolazine patents (with numbers)
3) Whether generics can enter now (in a specific country)
