Why it's free to use
- Filed February 15, 1983 and granted November 29, 1989. A European patent lasts at most 20 years from filing, so its term ended February 15, 2003.
- 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 August 15, 2008.
- 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.
