Patent share refers to the portion of a patent that is owned or shared by an individual or group. Synonyms for the term include patent ownership, patent stake, patent interest, patent equity or patent investment. Patent share is a valuable asset that can be bought, sold, licensed, or assigned. It allows the owner or the assignee to prevent others from making, using, selling, or importing an invention without permission. Patent share can also be transferred through inheritance, gift, or merger. It is important to understand patent share and its value in order to negotiate licenses or partnerships, as well as to protect one's own intellectual property rights.
