Patent applications, issued patents, or any interest therein, are legally assignable by an instrument in writing.See, e.g., MPEP § 301(I). “Assignment” corresponds to the act of transferring the entire ownership or a percentage of one’s property to another. A proper assignment must include the transfer to another of the entirety of the bundle of rights that is associated with the ownership interest, i.e., all of the bundle of rights that are inherent in the right, title and interest in the patent or patent application.See, e.g., MPEP § 301(II). An assignment may be recorded in the USPTO. Recordation of the assignment provides legal notice to the public of the assignment but does not speak to the validity of the assignment document or the effect of the assignment document on the ownership of the patent property.See, e.g., MPEP § 301(IV).
