The Federal Court of Australia today granted leave for Aristocrat to appeal against the rejection of its four innovation patents, which were found invalid on the basis of not defining patent eligible subject matter.  This case was previously the subject of a decision of the High Court of Australia, which was evenly split on the issue of patent eligibility for computer implemented inventions.  Hopefully sense will prevail and we will receive much needed guidance on patent protection for innovations in the important field of computer technology.  Updates will follow – watch this space!
