Why it's free to use
- Filed May 18, 2001 and granted March 31, 2004. A European patent lasts at most 20 years from filing, so its term ended May 18, 2021.
- 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.
