Read the whole patent

Listed from its IP Australia record in Patent Yard's archive of Australian patents past their term. Its claims, description and drawings are in the AusPat record and on Google Patents, and the Claude kit works from them.

Why it's free to use

• Filed January 20, 2004 and granted April 2, 2009. 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 January 20, 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.
