The Alice Guidance lists four example categories of abstract ideas:
- fundamental economic practices
- methods of organizing human activities
- an idea of itself (sic), and
- mathematical relationships/formulas.
Each of these examples has supporting footnotes to the Alice decision and other Supreme Court cases. But it should be understood that these categories are for potential Abstract Ideas. That is, something in one of these categories may or may not be an Abstract Idea. Taken superficially and out of context, some of these examples sweep too broadly, and will be too easily misused by examiners.
