Why it's free to use

  • Filed April 20, 1998 and granted September 24, 2003. A European patent lasts at most 20 years from filing, so its term ended April 20, 2018.
  • 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 October 20, 2023.
  • 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.
