Prior Art

Prior Art Searches


Prior art searches are intended to assist you in assessing the likelihood of patent protection being granted for your invention, and to draft and refine the scope of the claims in your patent application.


Novelty Search

A search for existing prior art describing all features of the proposed (or claimed) invention. This is aimed at uncovering any clear anticipation of your invention (ie a knock-out hit), and will usually involve a quite focused strategy.

Patentability Search

A search for existing prior art describing some or all features of the proposed (or claimed) invention. In addition to considering novelty, this search will use a broader strategy to try and uncover references that, alone or in combination, may have relevance with regard to obviousness or inventive step.
