38
copyright
a set of exclusive rights or protection given to creators of original ideas, information or other intellectual works
39
design rights
the rights of the creator of a design or designs. design rights do not, however, give protection to any 2d aspects of the design, e.g. patterns
40
intellectual property (IP)
all kinds of intangible (not physical) types of property that people can own for example, the relative outcomes from the mind such as design ideas, written material, artistic and musical composition
