Why it's free to use
- Filed October 19, 1999 and granted April 11, 2012. A European patent lasts at most 20 years from filing, so its term ended October 19, 2019.
- A supplementary protection certificate, which can extend a medicine or crop-protection patent, adds at most five and a half years, so even that would have ended by April 19, 2025.
- 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.
