Why it's free to use
- Filed August 31, 1998 and granted November 26, 2003. A European patent lasts at most 20 years from filing, so its term ended August 31, 2018.
- 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 March 2, 2024.
- 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.
