Patentable subject matter
Patentable subject matter is the patentability criterion which defines the types of innovation that can be patented. The goal of anti-software-patent campaigns is to have definitions of patentable subject matter clearly exclude software ideas.
For discussion of abolishing software patents in this way, see Exclude software from patentability.
For example, in all or most countries, mathematical formulas are considered not to be patentable subject matter. Therefore, even if a mathematical formula fulfils the other criteria (it's new, it's original, it's useful), it cannot be patented. This is the basis of the interest in software is math arguments.
Where is it defined?
In the USA, it's section §101 of the legislation.
