Which Merck (Merk) patent covers bisoprolol?
The provided information doesn’t specify which company name you mean by “Merk” (for example, Merck KGaA vs. Merck & Co.) or which country/market the patent question is for. “Bisoprolol” is also an older, widely used beta-blocker, so patent coverage depends heavily on the specific formulation, salt, manufacturing process, or jurisdiction.
If you share any of the following, I can pinpoint the likely patent record(s):
- The exact patent owner (e.g., Merck KGaA or Merck & Co.)
- Country (US, EP, UK, etc.)
- Whether you mean the original bisoprolol drug substance, a specific dosage form, or a combination product
How to search patents for bisoprolol tied to “Merck”
To find the right patent(s), search for combinations of:
- “bisoprolol” + “Merck” (or the correct corporate name)
- “bisoprolol” + “salt” (e.g., fumarate/hemifumarate wording if applicable)
- “bisoprolol” + “formulation” or “pharmaceutical composition”
- “bisoprolol” + “controlled release” / “extended release” if you’re asking about a specific product type
When do bisoprolol patents typically expire?
Because bisoprolol is an established medicine, many early patents have already expired in most regions. What may still have active protection is usually:
- New formulation patents (e.g., extended-release versions)
- Process patents
- Patents on specific fixed-dose combinations (if any)
So “Merk patent bisoprolol” could mean either an expired foundational patent or a later, narrower patent on a particular product type.
