MPEP 300 - Ownership and Assignment (4)

The MPEP outlines two main types of patent ownership:

  1. Individual ownership: ‘An individual entity may own the entire right, title and interest of the patent property. This occurs where there is only one inventor, and the inventor has not assigned the patent property.’
  2. Joint ownership: ‘Multiple parties may together own the entire right, title and interest of the patent property.’ This can occur in several scenarios:
  • Multiple partial assignees of the patent property
  • Multiple inventors who have not assigned their rights
  • A combination of partial assignee(s) and inventor(s) who have not assigned their rights

Understanding these ownership types is crucial for managing patent rights and making decisions about assignments or licenses.

For pre-AIA patent applications (filed before September 16, 2012), partial assignees have specific rights and requirements when it comes to patent ownership and prosecution. According to MPEP 324:

A partial assignee is any assignee of record having less than the entire right, title and interest in the application. Where at least one inventor retains an ownership interest together with the partial assignee(s), the combination of all partial assignees and inventors retaining ownership interest is needed to conduct the prosecution of an application.

This means that if there are multiple partial assignees or a combination of partial assignees and inventors, they must act together to prosecute the application. Additionally, when establishing ownership:

  • Each partial assignee must provide a submission under pre-AIA 37 CFR 3.73(b).
  • The extent of each assignee’s interest must be clearly stated.
  • The Office must be able to determine if it has obtained action by all of the right, title, and interest holders.

If the extent of ownership is not clear, the USPTO may refuse to accept the submission as an establishment of ownership interest.

How does joint ownership work for patents?

Joint ownership in patents occurs when two or more parties share ownership rights. The MPEP 301 provides guidance on this:

‘In the case of joint owners, each joint owner has the right to make, use, offer for sale, and sell the patented invention without the consent of and without accounting to the other owners.’

This means that each joint owner has full rights to use and profit from the patent independently, without needing permission from the other owners. However, this can lead to complications, especially in licensing or selling the patent, as all joint owners typically need to agree on such actions. It’s often advisable for joint owners to have a written agreement outlining their rights and responsibilities.

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.

MPEP 301-Ownership/Assignability of Patents and Applications (3)

The MPEP outlines two main types of patent ownership:

  1. Individual ownership: ‘An individual entity may own the entire right, title and interest of the patent property. This occurs where there is only one inventor, and the inventor has not assigned the patent property.’

MPEP 400 - Representative of Applicant or Owner (1)

No, a partial assignee cannot file a patent application as the sole applicant. The MPEP clarifies this point:

Because all parties having any portion of ownership in a patent property must act together as a composite entity in patent matters before the Office, a partial assignee (e.g., a party who owns 50% of the interest) cannot on its own file a patent application as the applicant.

This means that if multiple parties have ownership interests in the invention, they must act together to file the patent application. For more information on joint ownership, see MPEP § 301.
