Why it's free to use
- Filed July 14, 1981 and granted August 21, 1985. A European patent lasts at most 20 years from filing, so its term ended July 14, 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 January 14, 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.
