What does “Pradaxa patent 822” refer to?
“Pradaxa” is the brand name for dabigatran etexilate. The phrase “patent 822” typically points to a specific patent identifier (often the last digits of a U.S. patent number) tied to dabigatran or Pradaxa-related formulations or uses.
However, “patent 822” by itself is ambiguous: it doesn’t uniquely identify a single patent across jurisdictions or even across different numbering conventions (e.g., “US xxxx,822,” “EP 822…,” or internal references used by third parties).
Which Pradaxa patents are most commonly discussed for dabigatran (and how to locate “822”)?
For Pradaxa, patent discussions commonly focus on:
- Drug substance/formulation protections for dabigatran etexilate
- Specific dosing forms or manufacturing-related claims
- Method-of-use protections (for certain indications)
- Extension/secondary patents that can delay generic entry even after earlier patents expire
To identify the exact “822” patent you mean, you usually need one more detail: the full patent number, the country/jurisdiction (U.S. vs. EP, etc.), or the website/reference where “822” appears.
When does the relevant Pradaxa patent expire, and when could generics/biosimilars enter?
Patent expiration depends on the specific patent identified by “822,” plus any regulatory exclusivity and time extensions in the relevant market. The earliest generic entry timeline may differ from when the last secondary patent expires.
If you share the full patent number (or the link/source where you saw “822”), I can map it to:
- The patent holder
- The assignee/inventors
- The stated expiry date (and any known adjustments)
- The likely impact on generic competition
