An Assignment of Patent is a legal document used to transfer ownership of a patent from one entity to another. It can be used to transfer rights to the patent from the original patent holder to a third party or to transfer rights from one co-owner to another. This document outlines the transfer of ownership and includes the names of the parties involved, the date of the transfer, and details of the patent itself. Types of Assignment of Patent: 1. Absolute Assignment: A transfer of all rights and title in the patent from the assignor to the assignee. 2. Partial Assignment: A transfer of only certain rights and title in the patent from the assignor to the assignee. 3. Exclusive Assignment: A transfer of all rights and title in the patent from the assignor to the assignee with the restriction that the assignor is not allowed to transfer the patent to any other person. 4. Non-Exclusive Assignment: A transfer of all rights and title in the patent from the assignor to the assignee without any restrictions. The assignor is allowed to transfer the patent to multiple assignees.
