In 2001 Australia introduced an Innovation Patent. This required novelty and an innovative step, rather than an inventive step, issued after a month without examination and was valid for 8 years.
If requested to do so and if a fee was paid, the patent could be examined, thereby providing an enforceable right.
Thus the innovation patent is a kind of petty patent.
The Intellectual Property Laws Amendment (Productivity Commission Response Part 2 and Other Measures) Bill 2019 has now been passed by both houses of Australia’s Federal Parliament.
The amendment will abolish the innovation patent system in mid 2021. It does not have retroactive effect and existing rights will not be affected.
