Patents
Work through s 18 methodically for each individual claim
An invention will be a patentable invention for the purposes of a standard patent if the invention, so far as claimed in any claim:
1.
Manner of manufacturer within the meaning of s 6 Statute of Monopolies
?
2.
When compared with the prior art base as it existed before the priority date of that claim:
a.
Novel; and
b.
Involves an inventive step
3.
Useful
4.
Was not secretly used.
Manner of manufacture
ď‚·
For [X]'s invention to be patentable, it must be 'a manner of manufacture within the meaning of s 6 of the Statute of Monopolies (s 18(1)(a) PA). Invention is defined under Sch 1 PA as any manner of new manufacture the subject of letters patent and grant of privilege within s 6 of the Statute of Monopolies. ď‚·
The High Court in NRDC
, explained that this enquiry is not one that is based on the meaning of the word "manufacture" as such, but rather the "right question" is whether the claim is to a "proper subject of letters patent according to the principles which have been developed for the application" of s 6.
ď‚·
For a process to fall within the limits of patentability which the context of the Statute of Monopolies has supplied, must be one that offers some advantage which is material, in the sense that the process belongs to a useful art as distinct from a fine art that its value to the country is in the field of economic endeavour. That is, it requires a mode or manner of achieving an end result which is an artificially created state of affairs of utility in the field of economic endeavour.

ď‚·
For a patentable invention so far as claimed in a claim, the question is whether it is novel when compared with the prior art base before the priority date. ď‚·
The question is whether the prior publication is sufficient to make the claimed invention apparent to the skilled addressee: Nicaro at 561.
ď‚·
A prior publication will constitute an anticipation if it discloses all of the essential integers of the claim (
SNF v Ciba at [308])
ď‚·
Sufficiency of disclosure is a cardinal anterior requirement in the analysis of whether a prior art document anticipates a claimed invention (
Astrazeneca v Apotex at [302]). ď‚·

Test of obviousness
o
Base test
: 'The test is whether the hypothetical addressee faced with the same problem would have taken as a matter of routine whatever steps might have led from the prior art to the invention, whether they be the steps of the inventor or not.': Wellcome Foundation v VR Laboratories
per Aitkin J at 286. o
Combination patents
: 'The question is, is the invention itself obvious, not whether a diligent searcher might find pieces from which there might have been selected the elements which make up the patent. If this were not so, there could never be a valid patent for a new combination of old integers. The proper question is not whether it would have been obvious to the hypothetical addressee who was presented with an ex post facto selection of prior specifications that elements from them could be combined to produce a new product or process, it is rather whether it would have been obvious to a non-
inventive skilled worker in the field to select from a possibly very large range of publications the particular combination subsequently chosen by the opponent in the glare of hindsight and also whether it would have been obvious to that worker to select the particular combination of integers from those selected publications.' 3M v Beiersdorf
per Aickin J at 293

Common general knowledge - see MLA
ď‚·
Who is the person skilled in the art?
o
The correct identification of the level of skill of the skilled person, and the common general knowledge that such a person should be taken to possess, may therefore be particularly important where a "squeeze" arises between insufficiency and obviousness. The addressee of the patent must have sufficient skill and knowledge to put the invention into effect, for otherwise the patent will be insufficient. But the higher the level of skill and knowledge of those in the art, the greater the risk that the invention may be considered to be obvious.
