What is a patent reassignment?

A patent reassignment is an agreement for the owner of a patent transfer, sell or give away, his or her interest to an assignee.

The assignee appears on the cover page of a patent and references who owns the patent rights. If there is no assignee, it can be assumed that the inventors own the patent rights. 

Why do patents reassign their rights?

  •  Selling a patent 
  • Reorganisation structure
  • M&A
