RAND (reasonable and nondiscriminatory)

RAND, an abbreviation for reasonable and nondiscriminatory , is a phrase that ISO , the international standards group, and other groups use to describe terms to which a patent contributor to a standard must adhere. If a technology that is part of the standard is to be licensed for a fee, the terms must be nonexorbitant, published, and the same for all implementors (rather than subject to individual negotiation).

An approach that standards users prefer is royalty-free implementation.
