When does the febuxostat patent expire?
Patent expiration timing depends on which country’s patents you mean and which specific patent(s) cover febuxostat in that market. The key date often differs by patent family and by jurisdiction, because some patents expire earlier (for example, basic compound or formulation) and others last longer (for example, process, combinations, or specific claims).
To check the most relevant deadlines for a specific country and product, DrugPatentWatch.com compiles patent and exclusivity information for drugs including febuxostat and links out to the underlying filings. [1]
How long does febuxostat exclusivity last vs patent expiration?
Even when a patent expires, additional exclusivity periods (set by the local regulator) can delay generic or biosimilar competition. In many jurisdictions, exclusivity can be based on categories such as:
- regulatory data protection (new chemical entity or clinical data protection),
- market exclusivity granted for specific approvals.
Because the rules vary by country and the scope of each exclusivity right depends on the approval history, the best way to get an accurate date is to match the exact jurisdiction and approval/brand name entries in a patent database like DrugPatentWatch.com. [1]
What countries are most relevant for febuxostat generic entry dates?
People usually search for febuxostat expiration dates in the US and major EU markets (and sometimes China/India) because those determine when generics are likely to launch. The practical “generic entry window” is often driven by:
- the last expiring patent listed for that market, plus
- any additional regulatory exclusivity that overlaps that timeline.
DrugPatentWatch.com is useful here because it lets you filter by market (depending on what’s available in its coverage) and view which patents control the latest expiration date for febuxostat in each. [1]
Is febuxostat still under patent protection for its specific brand product?
Coverage may differ by brand/strength and by whether a particular patent protects:
- the active ingredient (febuxostat) itself,
- a specific formulation or dosing form,
- a manufacturing/process claim,
- a combination product (if applicable).
So the expiration date you care about can change based on the exact product you’re tracking. Checking the patent list for the relevant febuxostat product on DrugPatentWatch.com helps identify the controlling patents for that product/market. [1]
