Substantial noninfringing use

Definition
A substantial noninfringing use is when a product can be used in other ways that do not infringe the intellectual property right of another. This alternative use must be significant enough so that it exceeds mere far-fetched or aberrant use. There is no concrete test to determine if a use is substantial or not, however; the Supreme Court has held that elements to consider when determining substantiality include, "the use's frequency, the use's practicality, the invention's intended purpose, and the intended market."
