Patent Law FAQ
This FAQ answers all your questions about patent law, patent procedure, and the patent examination process.
MPEP 200 – Types and Status of Application; Benefit and Priority (1)
Divisional applications and provisional applications are distinct types of patent applications with different purposes and characteristics:
- Divisional Application: Claims subject matter from a prior non-provisional application that is independent and distinct from the original claims.
- Provisional Application: A temporary application that establishes a priority date but does not mature into an issued patent.
The MPEP explicitly states in MPEP ¶ 2.01:
“An application claiming the benefit of a provisional application under 35 U.S.C. 119(e) should not be called a ‘divisional’ of the prior application.”
This distinction is important because divisional applications claim the benefit under 35 U.S.C. 120, while provisional applications are claimed under 35 U.S.C. 119(e).

MPEP 300 – Ownership and Assignment (5)
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.

What happens if a patent assignment is not recorded with the USPTO?
Failing to record a patent assignment with the USPTO can have significant consequences:
- Lack of Constructive Notice: Third parties may not be aware of the ownership transfer.
- Potential Legal Issues: It may affect the assignee’s ability to enforce the patent or recover damages in infringement cases.
- Validity of Subsequent Transfers: As stated in MPEP 302, ‘An assignment recorded in the Office is regarded as valid, for purposes of recording, unless overcome by a showing that such assignment was fraudulently procured or is otherwise invalid.’
While recording is not mandatory for the assignment to be valid between the parties involved, it is highly recommended to protect the assignee’s rights and provide public notice of the ownership change.
For more information on USPTO, visit: USPTO.
To correct an error in a recorded assignment document at the USPTO, you have two main options:
- Cover sheet corrections: For errors in the cover sheet data only, you can submit a corrective document identifying the reel and frame number where the assignment is recorded and explaining the correction.
- Errors in the assignment document: For errors in the actual assignment document, you need to record a corrective document. This can be either a new assignment or other document correcting the original assignment.
As stated in MPEP 323: “The ‘Correction’ box on the Recordation Form Cover Sheet should be checked to indicate that the new submission is to correct an assignment already recorded.”
For more information on assignment correction, visit: assignment correction.

What happens if an assignment document is not recorded at the USPTO?
If an assignment document is not recorded at the USPTO, it can have significant legal implications. According to MPEP 302:
‘An assignment, grant, or conveyance of a patent or application shall be void as against any subsequent purchaser or mortgagee for valuable consideration, without notice, unless it is recorded in the Office within three months from its date or prior to the date of such subsequent purchase or mortgage.’
In other words, failing to record an assignment within the specified timeframe can render it invalid against subsequent purchasers or mortgagees who were unaware of the previous assignment. This highlights the importance of timely recording assignments to protect the rights of assignees.

For more information on USPTO, visit: USPTO.
To record an assignment of a patent or patent application, the following requirements must be met:
- The assignment must be in writing.
- It must be signed by the assignor (the person or entity transferring ownership).
- The document must identify the patent or application by number.
- The assignment must be submitted to the USPTO along with the required fee.
According to MPEP 301: “An assignment relating to a patent must be submitted to the USPTO for recordation as an absolute requirement for enforcing the patent or application against third parties.” This recordation provides constructive notice to the public of the assignment.

An oath is a sworn statement made before a person authorized to administer oaths, while a declaration is a written statement that can be used in lieu of an oath. According to MPEP 602, “A declaration may be submitted in lieu of an oath in any document filed in the Office provided the declaration complies with the requirements of 37 CFR 1.68.” Declarations are often preferred because they don’t require appearing before an official and are easier to process electronically.
