Why it's free to use

  • Filed December 14, 1983 and granted July 30, 1986. A European patent lasts at most 20 years from filing, so its term ended December 14, 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 14, 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.
