Why it's free to use
- Filed December 16, 2004 and granted July 4, 2007. A European patent lasts at most 20 years from filing, so its term ended December 16, 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.
