Open the AusPat recordNo Claude kit for weapons

Why it's free to use
- Filed April 16, 1981 and granted March 21, 1985. An Australian standard patent lasts 20 years from its date of patent, which is at most a year after this filing, so its term ended by April 16, 2002.
- A pharmaceutical extension adds at most five years, so even that would have ended by April 16, 2007.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
