Why it's free to use
- Filed May 12, 2003 and never granted as a European patent. Had it been granted, its 20-year term would have ended May 12, 2023.
- 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.
