Why it's free to use
- Filed February 29, 1928. Even if it was granted, its term would have ended by February 28, 1949.
- A pharmaceutical extension adds at most five years, so even that would have ended by March 1, 1954.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
