Patent Law FAQ

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).

No, a provisional patent application cannot claim priority to or benefit from other applications. The MPEP 201.04 clearly states:

“A provisional application is not entitled to the right of priority under 35 U.S.C. 119, 365(a), or 386(a) or § 1.55, or to the benefit of an earlier filing date under 35 U.S.C. 120, 121, 365(c), or 386(c) or § 1.78 of any other application.”

This means that a provisional application stands alone and cannot claim the filing date of any earlier U.S. or foreign application. However, it’s important to note that while a provisional application cannot claim priority, it can serve as a priority document for later-filed nonprovisional or foreign applications, provided they are filed within 12 months of the provisional application’s filing date.

The United States Patent and Trademark Office (USPTO) uses several criteria to determine if a claim is too broad. According to MPEP 2173.04, the assessment depends on the specific issues with the claim:

1. Inventor’s Regard: If the claim is broader than what the inventor regards as the invention, it may be rejected under 35 U.S.C. 112(b).
2. Lack of Support or Enablement: If the claim is not supported by the original description or lacks an enabling disclosure, it may be rejected under 35 U.S.C. 112(a).
3. Prior Art: If the claim is so broad that it reads on prior art, it may be rejected under 35 U.S.C. 102 or 103.

The MPEP states: “Undue breadth of the claim may be addressed under different statutory provisions, depending on the reasons for concluding that the claim is too broad.“

Examiners will analyze the claim language, specification, and prior art to make these determinations. It’s important to note that breadth alone does not make a claim too broad; the issue arises when the breadth leads to indefiniteness, lack of support, or overlap with prior art.

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.”

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.

No, a provisional patent application cannot claim priority to or benefit from other applications. The MPEP 201.04 clearly states:

“A provisional application is not entitled to the right of priority under 35 U.S.C. 119, 365(a), or 386(a) or § 1.55, or to the benefit of an earlier filing date under 35 U.S.C. 120, 121, 365(c), or 386(c) or § 1.78 of any other application.”

This means that a provisional application stands alone and cannot claim the filing date of any earlier U.S. or foreign application. However, it’s important to note that while a provisional application cannot claim priority, it can serve as a priority document for later-filed nonprovisional or foreign applications, provided they are filed within 12 months of the provisional application’s filing date.

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 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.

The United States Patent and Trademark Office (USPTO) uses several criteria to determine if a claim is too broad. According to MPEP 2173.04, the assessment depends on the specific issues with the claim:

1. Inventor’s Regard: If the claim is broader than what the inventor regards as the invention, it may be rejected under 35 U.S.C. 112(b).
2. Lack of Support or Enablement: If the claim is not supported by the original description or lacks an enabling disclosure, it may be rejected under 35 U.S.C. 112(a).
3. Prior Art: If the claim is so broad that it reads on prior art, it may be rejected under 35 U.S.C. 102 or 103.

The MPEP states: “Undue breadth of the claim may be addressed under different statutory provisions, depending on the reasons for concluding that the claim is too broad.“

Examiners will analyze the claim language, specification, and prior art to make these determinations. It’s important to note that breadth alone does not make a claim too broad; the issue arises when the breadth leads to indefiniteness, lack of support, or overlap with prior art.

An interference in patent law is a proceeding to determine which party has the right to a patent when two or more parties claim the same invention. The Manual of Patent Examining Procedure (MPEP) Chapter 2300 covers interference and derivation proceedings.

According to MPEP 2304, “The suggestion for an interference may come from an applicant or from an examiner.” This process is crucial in determining priority of invention when multiple parties claim the same or similar inventions.

Acting in a representative capacity refers to a patent practitioner appearing in person or signing papers on behalf of a client before the United States Patent and Trademark Office (USPTO) in a patent case. According to 37 CFR 1.34, when a patent practitioner acts in this capacity, their personal appearance or signature constitutes a representation that they are authorized to represent the particular party on whose behalf they are acting.

The MPEP states: “When a patent practitioner acting in a representative capacity appears in person or signs a paper in practice before the United States Patent and Trademark Office in a patent case, his or her personal appearance or signature shall constitute a representation to the United States Patent and Trademark Office that under the provisions of this subchapter and the law, he or she is authorized to represent the particular party on whose behalf he or she acts.”

No, a provisional patent application cannot claim priority to or benefit from other applications. The MPEP 201.04 clearly states:

“A provisional application is not entitled to the right of priority under 35 U.S.C. 119, 365(a), or 386(a) or § 1.55, or to the benefit of an earlier filing date under 35 U.S.C. 120, 121, 365(c), or 386(c) or § 1.78 of any other application.”

This means that a provisional application stands alone and cannot claim the filing date of any earlier U.S. or foreign application. However, it’s important to note that while a provisional application cannot claim priority, it can serve as a priority document for later-filed nonprovisional or foreign applications, provided they are filed within 12 months of the provisional application’s filing date.
