Why it's free to use
- Filed January 20, 1990 and granted May 25, 1994. A European patent lasts at most 20 years from filing, so its term ended January 20, 2010.
- 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 July 20, 2015.
- 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.
