MPEP 300 – Ownership and Assignment (1)

Joint ownership in patents and patent applications occurs when two or more parties share ownership rights. According to MPEP 301:

“Joint inventors are treated as joint owners of the invention unless there is an assignment.”

Key aspects of joint ownership include:

  • Each joint owner has the right to make, use, sell, and license the invention without consent from other owners.
  • Profits do not need to be shared unless there’s a specific agreement.
  • All joint owners must agree to sell or assign the entire patent to a third party.
  • In infringement suits, all joint owners must be joined as plaintiffs.

It’s important for joint owners to have clear agreements in place to avoid potential conflicts and ensure proper management of the patent rights.

Can the order of joint inventors’ names be changed after filing a patent application?

Yes, the order of joint inventors’ names can be changed after filing a patent application, but it requires a specific process. The MPEP 602.09 states:

“The order of names of joint patentees in the heading of the patent is taken from the order in which the names appear in the application papers unless changed by request.”

To change the order of inventors’ names:

  • Submit a request to the USPTO
  • Provide a statement from all the joint inventors agreeing to the change
  • Pay any required fees

It’s important to note that changing the order doesn’t affect inventorship rights but may impact how the patent is cited in literature. The request should be made before the patent is granted for it to appear in the correct order on the issued patent.
