Why it's free to use
- Filed May 24, 1954. Even if it was granted, its term would have ended by May 24, 1975.
- A pharmaceutical extension adds at most five years, so even that would have ended by May 24, 1980.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
