Substantial Copy Law and Legal Definition
Generally, making a substantial copy means copying a considerable or significant part of something. Substantial copying simply refers to more than just copying. The term substantial copy is often used in the context of Intellectual property. Substantial copy is a copy of a full, important, significant, or considerable amount of any work.
For instance, the Copyright Statute prevents other people from making a substantial copy of an individual's protected work, whether or not they are selling their art, entering it in competitions or perfecting their techniques. However, there is no precise definition of substantial copy. Under the Patent infringement laws, the Doctrine of Equivalents states that if public are at liberty to make substantial copies of a thing, varying its forms or proportions, then exclusive right to the thing patented is not secured.
