Why it's free to use
- Filed February 24, 2004. Even if it was granted, its term would have ended by February 24, 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.
