Why it's free to use

  • Filed August 27, 1982 and granted March 23, 1988. A European patent lasts at most 20 years from filing, so its term ended August 27, 2002.
  • 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 February 27, 2008.
  • 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.
