Thus the patentability criteria largely involves novelty, inventive step and industrial application or usability of the invention. In addition, section 3 of the Patent Act, 1970, also provides a list of non-patentable inventions for e.g. inventions that are frivolous or contrary to well established to natural laws. [8]
Together with criteria such as novelty, inventive step or nonobviousness, utility (or industrial applicability), which differ from country to country, the question of whether a particular subject matter is patentable is one of the substantive requirements for patentability.
Instead, the Federal Circuit and the USPTO adopted the machine-or-transformation test for patentability of processes. Judge Pauline Newman wrote a short dissent in In Re Bilski, arguing for a broader definition of the patentability of processes. [36] The US Supreme Court in its following cases (see below) essentially adopted the Newman's position.
In United States patent law, utility is a patentability requirement. [1] As provided by 35 U.S.C. § 101, an invention is "useful" if it provides some identifiable benefit and is capable of use and "useless" otherwise. [2]
The "patentability" of inventions (defining the types things that qualify for patent protection) is defined under Sections 100–105. Most notably, section 101 [9] sets out "subject matter" that can be patented; section 102 [10] defines "novelty" and "statutory bars" to patent protection; section 103 [11] requires that an invention to be "non ...
The purpose of the inventive step, or non-obviousness, requirement is to avoid granting patents for inventions which only follow from "normal product design and development", to achieve a proper balance between the incentive provided by the patent system, namely encouraging innovation, and its social cost, namely conferring temporary monopolies.
