Why it's free to use
- Filed October 8, 1979 and never granted as a European patent. Had it been granted, its 20-year term would have ended October 8, 1999.
- 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 April 8, 2005.
- 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.
