Why it's free to use

  • Filed November 11, 2002 and never granted as a European patent. Had it been granted, its 20-year term would have ended November 11, 2022.
  • Supplementary protection certificates extend only medicine and crop-protection patents, and it isn't classified as either.
  • 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.
