Why it's free to use
- Filed January 16, 1953. Even if it was granted, its term would have ended by January 16, 1974.
- A pharmaceutical extension adds at most five years, so even that would have ended by January 16, 1979.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
