In its 2010 report on patentable subject matter, the former Advisory Council on Intellectual Property (ACIP) considered that there are a number of problems with the current wording of the test for patentability in the Patents Act, that an invention be for a 'manner of new manufacture'. The language is obscure and does not match well with the case law developed by the courts to determine patentability, and the test overlaps with other areas of patent law. ACIP recommended that the wording of the test for patentable subject matter be updated to use clear and contemporary language embodying the principles developed by the courts. The government accepted this recommendation in its response of 23 November 2011.

There have been several recent changes to the case law of patentable subject matter. Time is required for the effects to be fully understood before this issue is considered further.
