Why it's free to use
- Filed November 10, 2005 and granted July 17, 2013. A European patent lasts at most 20 years from filing, so its term ended November 10, 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.
