Why it's free to use
- Filed December 6, 1983 and granted February 20, 1991. A European patent lasts at most 20 years from filing, so its term ended December 6, 2003.
- 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 6, 2009.
- 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.
