Why it's free to use
- Filed February 10, 2004 and granted January 21, 2010. 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 February 10, 2025.
- Term extensions apply only to pharmaceutical patents, and it isn't classified as one.
- We check Australian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
