Raising the Bar Act
Apparently, the Governor-General signed the Royal Assent to the Intellectual Property Laws Amendment (Raising the Bar) Act 2012 on 15 April 2012.
According to IP Australia, most of the amendments will not come into force until 15 April 2013, but the exceptions to patent infringement for (1) regulatory use or (2) experimental use are now in force.
Many of the changes yet to come into force do relate to patents. There are, however, important changes to trade mark registrability (amongst other things) and conferral of original jurisdiction (from 15 April 2013) on the Federal Magistrates Court in matters concerning registered designs, trade marks or PBR , including appeals from the Registrar, infringement and revocation proceedings.
