Patentable subject matter
Summary
Patentable, statutory or patent-eligible subject matter is subject matter of an invention that is considered appropriate for patent protection in a given jurisdiction. The laws and practices of many countries stipulate that certain types of inventions should be denied patent protection. Together with criteria such as novelty, inventive step or nonobviousness, utility, and 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.
The problem of patentable subject matter arises usually in cases of biological and software inventions, and much less frequently in other areas of technology.
The subject-matter which is regarded as patentable as a matter of policy, and correspondingly the subject-matter which is excluded from patentability as a matter of policy, depends on the national legislation or international treaty.
Subject matter in Canadian patent law
According to the Canadian Intellectual Property Office (CIPO) patents may only be granted for physical embodiments of an idea, or a process that results in something that is tangible or can be sold. This excludes theorems and computer programs per se. However, business methods are patentable.
The European Patent Convention (EPC) does not provide positive guidance on what should be considered an invention for the purposes of patent law. However, it provides in a non-exhaustive list of what are not to be regarded as inventions, and therefore not patentable subject matter:
The following in particular shall not be regarded as inventions within the meaning of paragraph 1:
(a) discoveries, scientific theories and mathematical methods;
(b) aesthetic creations;
(c) schemes, rules and methods for performing mental acts, playing games or doing business, and programs for computers;
(d) presentations of information.
