Why it's free to use
- Filed June 30, 2004 and granted August 13, 2008. A European patent lasts at most 20 years from filing, so its term ended June 30, 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.
