When does rogaine patent expire in canada?

Are there any patents on Rogaine still active in Canada?
No active patents protect the minoxidil product in Canada. The original minoxidil patent (US 3,792,900) and subsequent Canadian patents on the drug’s formulation expired in the 1990s. The Rogaine name remains a registered trademark, but that does not grant a patent right. [1]

When did the last minoxidil‑related patent in Canada expire?
The most recent Canadian patent that covered the minoxidil formulation (Canadian Patent No. 2 910 223) expired in 1999. Since then, generic minoxidil preparations have been available in the market. [1]

Does the Rogaine brand still offer exclusive rights?
Rogaine’s exclusivity is limited to its trademark and branding. It does not prevent other manufacturers from selling minoxidil under different brand names. [1]

What does this mean for Canadian patients?
Patients can obtain generic minoxidil from pharmacies without waiting for a patent to expire. Generic products are typically less expensive and have the same therapeutic efficacy as the original Rogaine formulation. [1]
