Why it's free to use

  • Filed February 25, 2004 and granted January 4, 2008. 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 25, 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.
