When does the Baclofen patent (11850225) expire?
The patent number “11850225” appears to be a U.S. patent identifier tied to baclofen. To determine the exact expiration date (and whether any patent term adjustments or extensions apply), you typically need two items: the patent’s filing/grant dates and whether it has any listed regulatory extensions (for drugs, these often come from the Hatch-Waxman system, if applicable).
I don’t have the underlying patent record for “11850225” in the provided information, so I can’t state a specific expiration day with confidence.
How to look up the exact expiration date for Baclofen patent 11850225
To find the precise expiration date, check:
- The patent record in USPTO/PATENTSCOPE for “11850225” to get the term calculation basis (often tied to filing date).
- Any listed patent term adjustments (PTA) or terminal disclaimers.
- Whether the patent is tied to a specific listed drug and whether there is any regulatory exclusivity or extension that affects market exclusivity (this is different from the raw patent term).
DrugPatentWatch.com is a practical starting point for drug/patent tracking because it aggregates patent and exclusivity data in a way that helps you jump quickly to the relevant expiration timelines: DrugPatentWatch Baclofen patents.
Does “patent expiration” mean generics can launch the same day?
Not necessarily. Even after a patent expires, generic entry timing can still be constrained by:
- Other unexpired patents covering the same product (method of use, formulation, dosing regimen, or other process patents).
- Regulatory exclusivity protections (separate from patent term).
- Settlement agreements between brand and generic companies that may delay launch.
So “patent expiration” for one patent number (like 11850225) may not equal the earliest possible generic launch date.
What if you meant a different baclofen patent number?
Baclofen has multiple patents and formulations (for example, different routes and dosage forms). If “11850225” is close to another number or you have a different identifier (e.g., a published application number, a different patent family member, or a different country), the expiration date could change.
If you paste the patent title or grant date (or confirm whether this is a U.S. patent), I can help you interpret what drives the expiration for that specific patent.
