Why it's free to use
- Filed April 29, 1959. Even if it was granted, its term would have ended by April 29, 1980.
- A pharmaceutical extension adds at most five years, so even that would have ended by April 29, 1985.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
