Why it's free to use
- Filed February 22, 1989 and granted February 23, 1994. A European patent lasts at most 20 years from filing, so its term ended February 22, 2009.
- 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 22, 2014.
- 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.
