The Commonwealth Department of Innovation Industry, Science and Research has published an Intellectual Property Scorecard 2002 – 2006.
There are a wealth of interesting statistics to ponder …
For example, there were 25,552 patent applications in 2006 (up from 22,569 in 2002), but only 9,426 granted (down from 13,702 in 2002) and the difference is not made up by the innovation patent which has had around 1000 – 1100 applications a year (although 1011 were granted in 2006 up from 758 in the very slow 2002).
Trade marks broke the 100,000 applications in a year in 2006, up from 64186 in 2002; 69910 applications were granted, up from 51699 in 2002.
More designs were granted than applied for in 2006; a measly 364 PBR applications went in and only 280 registrations were effected.
Did you know only 5% of patent applications are filed simultaneously in the US, Japan and the EPO?
There are lots of other details about who is patenting where, what classes they’re patenting in and so on.
