Why it's free to use
- Filed July 12, 1994 and granted August 20, 1997. A European patent lasts at most 20 years from filing, so its term ended July 12, 2014.
- 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 January 12, 2020.
- 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.
