Patent Assignment Law and Legal Definition

The owner of a patent may transfer, give or sell to another person the owner's interest in the patent. This type of agreement/gift is called an assignment, and the person who receives the owner's interest is called an assignee. An assignee has the right to exclude others from using the patent. To be enforceable, the assignment must be in writing and signed. It must also include the goodwill of the business connected with the mark.
