Why it's free to use
- Filed April 29, 1988 and granted January 8, 1992. A European patent lasts at most 20 years from filing, so its term ended April 29, 2008.
- 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 October 29, 2013.
- 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.
