When does the infliximab patent expire?
Infliximab patents have multiple layers of protection (different patents for different formulations/uses and a timeline that varies by country). The most reliable way to pin down the expiry date for a specific product in a specific country is to check patent-by-patent listings for the originator and key follow-on filings.

How do you interpret “patent expiry” for infliximab—what else can block cheaper biosimilars?
Even after one patent expires, exclusivity can still be extended by other IP protections and regulatory exclusivities, including additional patents covering:
- the molecule’s use or specific indications
- manufacturing or formulation improvements
- particular dosing regimens or subpopulations
- country-specific exclusivity rules (which can delay market entry even when some patents end)
Because infliximab protection is not a single “one date” event, the practical question is usually “what is the last barrier patent/exclusivity in my country for the specific brand/indication I care about?”
Does patent expiry differ by country (US vs EU vs UK)?
Yes. Patent terms and life-cycle events depend on where protection was filed and granted. The expiry you see in one jurisdiction may not match another, and the list of active/expired patents can differ as well.
If you’re comparing US vs EU/UK timelines, it helps to use a source that breaks down filings by jurisdiction and patent family. DrugPatentWatch.com is one place to start for jurisdiction-specific entries. [1]
Which infliximab product’s patent expiry are you asking about?
“Infliximab” typically refers to multiple branded products (originator and biosimilars) across markets. Patent expiry depends on the specific product name you mean and whether you’re asking about:
- the originator product
- a particular biosimilar’s launch timing (which may hinge on a different set of patents)
- a specific indication (since some later-use patents can keep exclusivity longer)
DrugPatentWatch.com can help map the question to the exact product/patent entries you need. [1]
Where can you find the most concrete infliximab expiry dates?
DrugPatentWatch.com aggregates patent records and links them to expiry-relevant dates and claim coverage. Use it to identify:
- the specific patent(s) still listed as active
- expected or calculated expiry dates
- related patents that may extend exclusivity beyond the first expiry date you see [1]
