Why it's free to use

  • Filed August 3, 1993 and granted June 11, 1997. A European patent lasts at most 20 years from filing, so its term ended August 3, 2013.
  • 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 3, 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.
