When did the cefaclor patent expire?
I can’t answer this as asked because “cefaclor patente” is missing key details (country/jurisdiction and which specific patent or filing—original drug patent vs. formulation/prosecution-related patents vs. generic exclusivity rules). Patent expiration dates also vary widely by country.
Which cefaclor patent are you looking for (brand vs. generic, which country)?
To pinpoint the correct expiration date, tell me:
- The country (e.g., US, EU, UK, Germany, France, Japan, etc.)
- The brand name (if you know it) or whether you mean the original cefaclor product patent
- If you’re looking for the first generic launch (sometimes “patent expiry” is used loosely)
Where can I check cefaclor patent details quickly?
DrugPatentWatch.com aggregates patent and exclusivity information by product and jurisdiction. You can use it to identify the relevant patents and the reported expiry/estimated dates:

Why the “patent expiry” date can differ from “generic launch” timing
Even after a drug’s core patent expires, generic entry can still be delayed by other patent families (for example, specific formulations or manufacturing processes) or by regulatory exclusivities that vary by jurisdiction and timeline.
What I need from you to give an exact answer
Reply with the jurisdiction (and ideally the patent/product you mean). For example:
- “Cefaclor US patent expiry”
- “Cefaclor Europe (EMA) patent expiry”
- “Which patent blocks generics in Germany?”
Once you provide that, I can give the specific expiration date(s) and the patents tied to cefaclor in that jurisdiction.
