Why it's free to use
- Filed March 21, 1996 and granted September 19, 2001. A European patent lasts at most 20 years from filing, so its term ended March 21, 2016.
- 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 September 21, 2021.
- 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.
