Why it's free to use
- Filed February 16, 1995 and granted July 21, 1999. A European patent lasts at most 20 years from filing, so its term ended February 16, 2015.
- 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 August 16, 2020.
- 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.
