Why it's free to use

  • Filed December 27, 1999 and granted May 19, 2004. A European patent lasts at most 20 years from filing, so its term ended December 27, 2019.
  • 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 27, 2025.
  • 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.
