Why it's free to use
- Filed June 1, 1994 and granted September 17, 1997. A European patent lasts at most 20 years from filing, so its term ended June 1, 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 December 1, 2019.
- 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.
