Why it's free to use
- Filed March 21, 2005 and never granted as a European patent. Had it been granted, its 20-year term would have ended March 21, 2025.
- 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.
