"Intellectual property is also critical to the creation and successful use of new knowledge – particularly the 'cumulative' use of knowledge as an input to further, better knowledge. In this regard, particularly in new areas of patenting such as software and business methods, there is strong evidence that existing intellectual property arrangements are hampering innovation. To address this, the central design aspects of all intellectual property needs to be managed as an aspect of economic policy. Arguably, the current threshold of inventiveness for existing patents is also too low. The inventive steps required to qualify for patents should be considerable, and the resulting patents must be well defined, so as to minimise litigation and maximise the scope for subsequent innovators."
