Why it's free to use

  • Filed September 20, 2004 and granted August 31, 2011. A European patent lasts at most 20 years from filing, so its term ended September 20, 2024.
  • 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.
