Why it's free to use
- Filed November 23, 1981 and granted February 26, 1986. A European patent lasts at most 20 years from filing, so its term ended November 23, 2001.
- 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 May 23, 2007.
- 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.
