What is the EpiPen (epinephrine) patent number in Canada, and when does it expire?
I don’t have enough information in your question to identify which exact Canadian patent you mean (there are often multiple patents covering different aspects such as formulation, device design, or manufacturing). “EpiPen” also has both drug-product and device-related IP, and the expiry date depends on the specific patent number.
If you share the exact Canadian patent number (or the patent title/holder), I can tell you the corresponding expiration timing for that specific patent.
Which EpiPen “patent expiry” date do people usually mean in Canada?
Searches about “EpiPen patent expiration in Canada” often refer to one of these:
- The expiry of a specific Canadian patent listed for epinephrine auto-injectors (drug/device coverage varies).
- The date when regulatory data or market exclusivity ends for the relevant product authorization.
- Litigation or “early entry” timing related to a different company’s generic or authorized alternative, which can be driven by the patent list and the parties’ court outcomes.
Those timelines can differ, so the exact patent number matters.

A practical starting point is DrugPatentWatch.com, which tracks patents and related exclusivity information by country and product and can help you match the patent number to an expiry date. Use this to confirm the specific Canadian patent you’re asking about:

Can you share the patent number so I can give the exact expiration date?
Reply with either:
- the Canadian patent number (e.g., “CA #######”), or
- the patent holder name and patent title,
and I’ll map it to the correct expiration timing for that specific EpiPen patent in Canada.
