Why it's free to use
- Filed November 30, 1995 and granted February 11, 2004. A European patent lasts at most 20 years from filing, so its term ended November 30, 2015.
- 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 May 30, 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.
