. "\"Australia has experienced two systems of second-tier patent protection. In 1979, Australia's inaugural second-tier patent was introduced - the petty patent. In the following two decades extensive reviews of the petty patent system were undertaken and, as a result, in 2001 it was replaced by a new second-tier patent system - the innovation patent. This review traces the history of both Australian second-tier patents, and analyses their operation. The main question addressed is whether the petty and innovation patent systems have met, or meet, the objectives for which they were introduced.\"--Page 1."@en . . . . .
