Patent Law FAQ

The terms ‘right of priority’ and ‘benefit of an earlier filing date’ refer to different concepts in US patent law:

• Right of priority: This term is used in the context of foreign priority under 35 U.S.C. 119(a)-(d) and 365(a) and (b). It allows a US application to claim the priority date of a foreign application filed within the previous 12 months.
• Benefit of an earlier filing date: This term is used for domestic benefit under 35 U.S.C. 119(e) and 120. It allows a US application to claim the filing date of an earlier US provisional or nonprovisional application.

As stated in MPEP 216: ‘The right of priority is a statutory right, which is not considered an application property right.’

What are the requirements for claiming domestic benefit in a patent application?

Claiming domestic benefit in a patent application allows an applicant to rely on the filing date of an earlier-filed US application. The MPEP 216 outlines the requirements for claiming domestic benefit, which are based on 35 U.S.C. 120. The key requirements include:

• The later-filed application must be filed before the patenting or abandonment of the prior application
• The later-filed application must contain or be amended to contain a specific reference to the prior application
• The prior application must disclose the invention claimed in the later-filed application in the manner required by 35 U.S.C. 112(a)
• At least one inventor named in the later-filed application must have been named as an inventor in the prior application

The MPEP states:

‘To be entitled to the benefit of the filing date of an earlier-filed application, the later-filed application must be an application for a patent for an invention which is also disclosed in the prior application.’

It’s important to note that these requirements must be met for each application in the chain of priority, ensuring a continuous line of co-pendency and proper disclosure.

A later-filed application for patent in the United States may claim the benefit of, or priority to, a prior application under certain conditions. These conditions are outlined in various U.S. statutes and regulations:

• For domestic benefit claims: 35 U.S.C. 119(e), 120, 121, 365(c), and 386(c); see also 37 CFR 1.78
• For foreign priority claims: 35 U.S.C. 119(a)-(d) and (f), 365(a) and (b), and 386(a) and (b); see also 37 CFR 1.55

The specific requirements and time frames may vary based on the filing date of the later-filed nonprovisional application and the type of priority or benefit claim being made.

To claim the benefit of a prior application’s filing date in a continuation-in-part (CIP) application, inventors must follow specific procedures. As noted in MPEP ¶ 2.06:

Should applicant desire to claim the benefit of the filing date of the prior application, attention is directed to 35 U.S.C. 120, 37 CFR 1.78, and MPEP § 211 et seq.

This involves properly referencing the prior application in the CIP application and ensuring that the CIP is filed before the patenting, abandonment, or termination of proceedings on the prior application. It’s crucial to follow the guidelines in MPEP § 211 for claiming domestic benefit.

Yes, a US patent application can claim both foreign priority and domestic benefit simultaneously. This is known as a ‘multiple priority claim’ or ‘multiple benefit claim.’ The MPEP 216 states:

‘It is possible for a U.S. application to be entitled to the benefit of an earlier U.S. filing date and also to the right of priority of a foreign application.’

Here’s how it works:

• The application can claim foreign priority under 35 U.S.C. 119(a)-(d) to a foreign application filed within the past 12 months.
• At the same time, it can claim domestic benefit under 35 U.S.C. 120 to an earlier US application.
• The earlier US application can also claim foreign priority to the same foreign application.

This allows the US application to potentially have an effective filing date that is earlier than both its actual filing date and the filing date of the US application it claims benefit from.

Claiming priority and claiming benefit are two different mechanisms in patent law, though both can affect the effective filing date of a patent application:

1. Claiming Priority:
   • Typically refers to claiming the right of priority to a foreign application under 35 U.S.C. 119(a)-(d) and (f)
   • Also includes priority claims to provisional applications under 35 U.S.C. 119(e)
   • Governed by 37 CFR 1.55 for foreign priority claims
2. Claiming Benefit:
   • Refers to claiming the benefit of an earlier filing date of a U.S. application under 35 U.S.C. 120, 121, 365(c), or 386(c)
   • Typically used for continuation, divisional, or continuation-in-part applications
   • Governed by 37 CFR 1.78

The MPEP discusses both types of claims: “Under certain conditions and on fulfilling certain requirements, a later-filed application for patent filed in the United States may claim the benefit of, or priority to, a prior application filed in the United States (see 35 U.S.C. 119(e), 120, 121, 365(c), and 386(c); see also 37 CFR 1.78) or in a foreign country (see 35 U.S.C. 119(a)-(d) and (f), 365(a) and (b), and 386(a) and (b); see also 37 CFR 1.55).”

Foreign priority claims and domestic benefit claims are two different ways of claiming the benefit of an earlier filing date:

• Foreign priority claims (under 35 U.S.C. 119(a)-(d)) are based on earlier applications filed in foreign countries
• Domestic benefit claims can be to earlier U.S. provisional (35 U.S.C. 119(e)) or nonprovisional (35 U.S.C. 120) applications

Key differences include:

• Time limits: 12 months for foreign priority, 12 months for provisionals, no limit for nonprovisionals
• Required documents: Certified copy needed for foreign priority, not for domestic benefit
• Effect: Foreign priority is mainly for prior art purposes, domestic benefit can confer actual pendency benefits

Both types of claims must be properly made to be effective, but the specific requirements and effects differ.

Claiming priority to a provisional application is different from claiming foreign priority. To claim the benefit of a provisional application in a later-filed nonprovisional application:

• The nonprovisional must be filed within 12 months of the provisional filing date
• A specific reference to the provisional application must be made in an application data sheet
• The provisional and nonprovisional must name at least one common inventor
• The claimed subject matter must be supported by the provisional application

This is known as a domestic benefit claim under 35 U.S.C. 119(e), rather than a foreign priority claim under 35 U.S.C. 119(a)-(d). The requirements are specified in 37 CFR 1.78 rather than 37 CFR 1.55.

To claim the benefit of a prior application’s filing date in a continuation-in-part (CIP) application, inventors must follow specific procedures. As noted in MPEP ¶ 2.06:

• The claimed subject matter must be supported by the provisional application

In patent applications filed before September 16, 2012, an Application Data Sheet (ADS) can significantly impact the priority claim process. The ADS can be used to:

• Provide domestic benefit information
• Include foreign priority information
• Correct or update priority claims within certain timeframes

According to MPEP 601.05(b): “For applications filed before September 16, 2012, an application data sheet may be used to provide or correct benefit claim information, such as cross-references to one or more prior-filed applications… The benefit claim must be set forth in the ADS in order to be considered properly submitted.”

It’s crucial to note that while the ADS can be used to submit priority information, applicants must still comply with other statutory requirements and deadlines for claiming priority. The ADS provides a centralized location for this information, potentially simplifying the application process and reducing errors in priority claims.
