Why it's free to use
- Filed December 19, 1997 and never granted as a European patent. Had it been granted, its 20-year term would have ended December 19, 2017.
- A supplementary protection certificate, which can extend a medicine or crop-protection patent, adds at most five and a half years, so even that would have ended by June 19, 2023.
- We check European rights only. A US or other national patent in its family could still be in force: check its family on Espacenet or Google Patents.
