 The High Court of Australia has refrained from ruling on the precise definition of manner of manufacture stating that any such attempt is bound to fail for the policy reason of encouraging national development in fields that may be unpredictable.In assessing whether an invention is a manner of manufacture, the High Court has relied on the inquiry of whether the subject of the claims defining the invention has as its end result an "artificially created state of affairs".In a decision of the Federal Court of Australia, on the patentability of an improved method of representing curved images in computer graphics displays, it was held that the application of selected mathematical methods to computers may involve steps which are foreign to the normal use of computers and hence amount to a manner of manufacture.
