Patent Law FAQ
This FAQ answers all your questions about patent law, patent procedure, and the patent examination process.
MPEP 300 – Ownership and Assignment (13)
No, including government support information on a provisional application cover sheet is not sufficient to meet the requirements of 35 U.S.C. 202(c)(6). The MPEP states:
Providing information concerning government support on a provisional application cover sheet does not satisfy the requirement of 35 U.S.C. 202(c)(6) which requires that the a statement be included within the specification of such application and any patent issuing thereon specifying that the invention was made with Government support and that the Government has certain rights in the invention.
The government license rights statement must be included within the specification itself, not just on the cover sheet.
Recording business name changes and mergers is crucial for maintaining an accurate chain of title for patents. MPEP 314 emphasizes this importance:
- For name changes:
Although a mere change of name does not constitute a change in legal entity, it is properly a link in the chain of title.
- For mergers:
Documents of merger are also proper links in the chain of title.
Recording these changes ensures:
- The USPTO has up-to-date information on patent ownership
- Third parties can accurately identify the current patent owner
- The chain of title remains clear and unbroken, which can be important for future transactions or litigation
- Compliance with legal requirements for maintaining patent rights
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.
The USPTO has specific provisions for handling partial assignees in patent issuance:
- If one or more assignees, together with one or more inventors, hold the entire right, title, and interest in the application, the patent may issue in the names of both the assignee(s) and the inventor(s).
- If multiple assignees hold the entire right, title, and interest to the exclusion of all inventors, the patent may issue in the names of the multiple assignees.
This is outlined in 37 CFR 3.81(c): (1) If one or more assignee, together with one or more inventor, holds the entire right, title, and interest in the application, the patent may issue in the names of the assignee and the inventor. (2) If multiple assignees hold the entire right, title, and interest to the exclusion of all the inventors, the patent may issue in the names of the multiple assignees.
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.
For more information on cover sheet, visit: cover sheet.
For more information on USPTO, visit: USPTO.
To correct assignee information on an issued patent, you must follow these steps:
- Submit a request for a certificate of correction under 37 CFR 1.323.
- Ensure that a request under 37 CFR 3.81(b) has been granted.
- Confirm that the assignment was submitted for recordation before the patent was issued.
According to MPEP 307: “A request for a certificate of correction under 37 CFR 1.323 (see MPEP §§ 1481 and 1485) arising from incomplete or erroneous assignee’s name furnished, or a missing assignee’s name, in item 3 of PTOL-85B will not be granted unless a request under 37 CFR 3.81(b) has been granted and the assignment was submitted for recordation as set forth in 37 CFR 3.11 before the patent issued.”
The request should be directed to the Office of Petitions and include:
- The processing fee required by 37 CFR 1.17(i)
- A request for issuance of the application in the name of the assignee, or a request that a patent be corrected to state the name of the assignee
- A statement that the assignment was submitted for recordation before the patent was issued
- A request for a certificate of correction under 37 CFR 1.323 with the associated fee

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 assignment recording, visit: assignment recording.
For more information on legal implications, visit: legal implications.
For more information on patent rights, visit: patent rights.
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.
For more information on patent assignment, visit: patent assignment.
For more information on recordation, visit: recordation.
For more information on USPTO, visit: USPTO.
An assignment and a 37 CFR 3.73(c) statement serve different purposes in the patent application process:
- Assignment: This is the actual transfer of ownership rights from the inventor(s) to the assignee.
- 37 CFR 3.73(c) statement: This is a document filed with the USPTO to establish the assignee’s right to take action in a patent application.
As stated in MPEP 325: “The submission of the statement pursuant to 37 CFR 3.73(c) is not required if a 37 CFR 3.73(b) statement has been previously filed in the application or patent prior to September 16, 2012.” This highlights that the 3.73(c) statement is a procedural document for USPTO purposes, while the assignment is the substantive transfer of rights.
For more information on USPTO procedures, visit: USPTO procedures.
What is the difference between recording a license and an assignment at the USPTO?
The main difference between recording a license and an assignment at the USPTO lies in the transfer of ownership rights:
- Assignment: Transfers ownership of the patent or application to another party.
- License: Grants permission to use the patent or application without transferring ownership.
According to MPEP 313: Other documents relating to interests in patents or applications will be recorded as provided in 37 CFR 3.11(a).
This includes licenses, which are recorded to provide notice of the agreement but do not change the ownership records at the USPTO.
How are historical patent assignment records maintained?
The USPTO maintains historical patent assignment records separately from more recent records. MPEP 301.01 explains:
‘The historical database of assignments is maintained separate and apart from the database of assignments affecting title recorded since 1980.’
This means that:
- Records prior to August 1980 are kept in a separate historical database
- These older records may not be available through the online Patent Assignment Search
- Accessing historical records may require different procedures or direct contact with the USPTO
For researchers or legal professionals needing access to pre-1980 assignment records, it’s advisable to contact the USPTO’s Patent and Trademark Resource Centers or the Assignment Recordation Branch for assistance.
What information is available in the USPTO’s assignment database?
The USPTO’s assignment database contains a wealth of information related to patent ownership. According to MPEP 301.01:
‘The USPTO maintains a database containing the assignment records of patents and patent applications. The USPTO also maintains a cumulative index of number of assignments recorded on the day in which they are recorded.’
The database typically includes:
- Patent or application numbers
- Names of assignors and assignees
- Dates of assignment execution and recording
- Brief descriptions of the interests conveyed
- Reel and frame numbers for locating documents
This information is crucial for determining the current ownership status of patents and applications, which is essential for various legal and business purposes.

The USPTO has specific provisions for handling partial assignees in patent issuance:
- If one or more assignees, together with one or more inventors, hold the entire right, title, and interest in the application, the patent may issue in the names of both the assignee(s) and the inventor(s).
- If multiple assignees hold the entire right, title, and interest to the exclusion of all inventors, the patent may issue in the names of the multiple assignees.
This is outlined in 37 CFR 3.81(c): (1) If one or more assignee, together with one or more inventor, holds the entire right, title, and interest in the application, the patent may issue in the names of the assignee and the inventor. (2) If multiple assignees hold the entire right, title, and interest to the exclusion of all the inventors, the patent may issue in the names of the multiple assignees.
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.”

To correct assignee information on an issued patent, you must follow these steps:
- Submit a request for a certificate of correction under 37 CFR 1.323.
- Ensure that a request under 37 CFR 3.81(b) has been granted.
- Confirm that the assignment was submitted for recordation before the patent was issued.
According to MPEP 307: “A request for a certificate of correction under 37 CFR 1.323 (see MPEP §§ 1481 and 1485) arising from incomplete or erroneous assignee’s name furnished, or a missing assignee’s name, in item 3 of PTOL-85B will not be granted unless a request under 37 CFR 3.81(b) has been granted and the assignment was submitted for recordation as set forth in 37 CFR 3.11 before the patent issued.”
The request should be directed to the Office of Petitions and include:
- The processing fee required by 37 CFR 1.17(i)
- A request for issuance of the application in the name of the assignee, or a request that a patent be corrected to state the name of the assignee
- A statement that the assignment was submitted for recordation before the patent was issued
- A request for a certificate of correction under 37 CFR 1.323 with the associated fee

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.

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 assignment and a 37 CFR 3.73(c) statement serve different purposes in the patent application process:
- Assignment: This is the actual transfer of ownership rights from the inventor(s) to the assignee.
- 37 CFR 3.73(c) statement: This is a document filed with the USPTO to establish the assignee’s right to take action in a patent application.
As stated in MPEP 325: “The submission of the statement pursuant to 37 CFR 3.73(c) is not required if a 37 CFR 3.73(b) statement has been previously filed in the application or patent prior to September 16, 2012.” This highlights that the 3.73(c) statement is a procedural document for USPTO purposes, while the assignment is the substantive transfer of rights.

What is the difference between recording a license and an assignment at the USPTO?
The main difference between recording a license and an assignment at the USPTO lies in the transfer of ownership rights:
- Assignment: Transfers ownership of the patent or application to another party.
- License: Grants permission to use the patent or application without transferring ownership.
According to MPEP 313: Other documents relating to interests in patents or applications will be recorded as provided in 37 CFR 3.11(a).
This includes licenses, which are recorded to provide notice of the agreement but do not change the ownership records at the USPTO.
How are historical patent assignment records maintained?
The USPTO maintains historical patent assignment records separately from more recent records. MPEP 301.01 explains:
‘The historical database of assignments is maintained separate and apart from the database of assignments affecting title recorded since 1980.’
This means that:
- Records prior to August 1980 are kept in a separate historical database
- These older records may not be available through the online Patent Assignment Search
- Accessing historical records may require different procedures or direct contact with the USPTO
For researchers or legal professionals needing access to pre-1980 assignment records, it’s advisable to contact the USPTO’s Patent and Trademark Resource Centers or the Assignment Recordation Branch for assistance.
What information is available in the USPTO’s assignment database?
The USPTO’s assignment database contains a wealth of information related to patent ownership. According to MPEP 301.01:
‘The USPTO maintains a database containing the assignment records of patents and patent applications. The USPTO also maintains a cumulative index of number of assignments recorded on the day in which they are recorded.’
The database typically includes:
- Patent or application numbers
- Names of assignors and assignees
- Dates of assignment execution and recording
- Brief descriptions of the interests conveyed
- Reel and frame numbers for locating documents
This information is crucial for determining the current ownership status of patents and applications, which is essential for various legal and business purposes.
