MPEP 200 – Types and Status of Application; Benefit and Priority (2)
Incorporating by reference in patent applications can have significant impacts:
- It allows applicants to include the content of another document without reproducing it in full.
- The incorporated material becomes part of the application as if it were explicitly included.
- It can provide support for claims and help meet disclosure requirements.
MPEP 211.05 mentions:
An incorporation by reference statement added after an application’s filing date is not effective because no new matter can be added to an application after its filing date (see 35 U.S.C. 132(a)).
This highlights the importance of including incorporation by reference statements at the time of filing to ensure their effectiveness. Applicants should carefully consider what materials to incorporate and ensure they are properly referenced to support their claims and meet disclosure requirements.

Benefit claims in Continued Prosecution Applications (CPAs) have some unique characteristics:
- A CPA automatically includes a specific reference under 35 U.S.C. 120 to the prior application
- No additional amendment to the specification or application data sheet is required to claim benefit
- A CPA is considered to reference every application in the chain with the same application number
- Priority claims under 35 U.S.C. 119(a)-(d) from the parent application automatically carry over to the CPA
The MPEP states: A request for a CPA is the specific reference required by 35 U.S.C. 120 to every application assigned the application number identified in such request. No further amendment to the specification of the CPA nor a reference in the CPA’s application data sheet is required by 35 U.S.C. 120 or 37 CFR 1.78(d) to identify or reference the prior application, as well as any other application assigned the application number of the prior application (e.g., in instances in which a CPA is the last in a chain of CPAs).
It’s important to note that applicants cannot delete benefit claims to certain applications in a chain of CPAs. The MPEP clarifies: Therefore, regardless of whether an application is filed under 37 CFR 1.53(b) or (d), a claim under 35 U.S.C. 120 to the benefit of a CPA is, by operation of 37 CFR 1.53(d)(7) and 37 CFR 1.78(d)(4), a claim to every application assigned the application number of such CPA. In addition, applicants will not be permitted to delete such a benefit claim as to certain applications assigned that application number (e.g., for patent term purposes).

MPEP 200 – Types and Status of Application; Benefit and Priority Claims (1)
Cross-noting in patent applications refers to the process of recording and verifying information about prior applications, including U.S. and foreign applications, for which benefit or priority is claimed. This information is typically noted on the bibliographic data (bib-data) sheet of the application and is used to ensure accurate representation of priority claims on the front page of a printed patent.
According to MPEP 202, “The front page of a printed patent identifies all prior applications for which benefits are claimed under 35 U.S.C. 119(e), 120, 121, 365(c), or 386(c) in continuation-in-part, continuation, divisional, and reissue applications.”

MPEP 2100 – Patentability (2)
Product-by-process claims and method claims are distinct types of patent claims with different scopes and considerations:
- Product-by-process claims are directed to the product itself, defined by the process used to make it. The patentability is based on the product, not the process.
- Method claims are directed to the process or steps used to make a product or achieve a result.
According to MPEP 2113:
“The structure implied by the process steps should be considered when assessing the patentability of product-by-process claims over the prior art.”
Key differences include:
- Focus: Product-by-process claims focus on the end product; method claims focus on the process steps.
- Infringement: Product-by-process claims are infringed by identical products, regardless of how they’re made; method claims are infringed only when the specific steps are performed.
- Examination: Product-by-process claims are examined based on the product structure; method claims are examined based on the specific steps and their order.
Understanding these differences is crucial for proper claim drafting and patent strategy.

35 U.S.C. 102(a)(2) applies to certain patent documents as prior art. The MPEP states:
“U.S. patents, U.S. patent applications published under 35 U.S.C. 122(b), and international patent applications published under the Patent Cooperation Treaty to another are prior art under 35 U.S.C. 102(a)(2) if the effectively filed date of the disclosure of the reference is before the effective filing date of the claimed invention.”
Key points to understand:
- The reference’s effectively filed date must be before the claimed invention’s effective filing date
- The reference can be prior art even if its publication date is after the claimed invention’s effective filing date
- 35 U.S.C. 102(d) determines when subject matter in these documents was “effectively filed”
Exceptions to 102(a)(2) prior art are provided in 35 U.S.C. 102(b)(2), including disclosures of the inventor’s own work and common ownership scenarios.

MPEP 2400 – Biotechnology (4)
A Sequence Identifier (SEQ ID NO) is a unique number assigned to each disclosed nucleic acid and/or amino acid sequence in a patent application. According to MPEP 2422.01:
“37 CFR 1.821(d) and 37 CFR 1.823(a)(5) require that each disclosed nucleic acid and/or amino acid sequence in the application appear separately in the “Sequence Listing”, with each sequence further being assigned a sequence identifier, referred to as “SEQ ID NO:” or the like.“
Key points about Sequence Identifiers:
- They must begin with 1 and increase sequentially by integers.
- Each sequence must have a different number for identification.
- Sequences should be presented in numerical order in the “Sequence Listing” where practical.
- When discussing a sequence in the description or claims, a reference to its SEQ ID NO is required at all occurrences.
- SEQ ID NOs can be used to discuss or claim parts of a sequence (e.g., “residues 14 to 243 of SEQ ID NO:23”).
The use of SEQ ID NOs provides a shorthand way for applicants to discuss and claim their inventions without restricting how an invention can be claimed.
To learn more:
Sequence identifiers (SEQ ID NOs) are crucial in patent applications containing nucleotide and/or amino acid sequences. According to MPEP 2421.02:
- Each disclosed nucleotide and/or amino acid sequence must be assigned a unique SEQ ID NO.

What is the significance of the application filing date for new matter in patent applications?
The application filing date is crucial when determining whether content in a patent application constitutes new matter. MPEP 608.04(a) states:
‘Matter not present on the filing date of the application in the specification, claims, or drawings that is added after the application filing date is new matter.’
This means that any information added to the application after the filing date, which was not present in the original specification, claims, or drawings, is considered new matter. This is important because new matter cannot be added to an application without filing a continuation-in-part application.
The filing date serves as a cutoff point for the content that can be included in the application without being considered new matter. Inventors and patent practitioners must ensure that all necessary information is included in the application on or before the filing date to avoid issues with new matter.

- Priority claims under 35 U.S.C. 119(a)-(d) from the parent application automatically carry over to the CPA
The MPEP states: A request for a CPA is the specific reference required by 35 U.S.C. 120 to every application assigned the application number identified in such request. No further amendment to the specification of the CPA nor a reference in the CPA’s application data sheet is required by 35 U.S.C. 120 or 37 CFR 1.78(d) to identify or reference the prior application, as well as any other application assigned the application number of the prior application (e.g., in instances in which a CPA is the last in a chain of CPAs).
It’s important to note that applicants cannot delete benefit claims to certain applications in a chain of CPAs. The MPEP clarifies: Therefore, regardless of whether an application is filed under 37 CFR 1.53(b) or (d), a claim under 35 U.S.C. 120 to the benefit of a CPA is, by operation of 37 CFR 1.53(d)(7) and 37 CFR 1.78(d)(4), a claim to every application assigned the application number of such CPA. In addition, applicants will not be permitted to delete such a benefit claim as to certain applications assigned that application number (e.g., for patent term purposes).

For inventions made with government support, contractors must include a specific statement at the beginning of the patent application and any resulting patents. This requirement is mandated by 35 U.S.C. 202(c)(6). The statement should read:
“This invention was made with government support under (identify the contract) awarded by (identify the Federal agency). The government has certain rights in the invention.”
This statement ensures transparency regarding government involvement and rights in the invention.

Patent Procedure (15)
Product-by-process claims and method claims are distinct types of patent claims with different scopes and considerations:
- Product-by-process claims are directed to the product itself, defined by the process used to make it. The patentability is based on the product, not the process.
- Method claims are directed to the process or steps used to make a product or achieve a result.
According to MPEP 2113:
“The structure implied by the process steps should be considered when assessing the patentability of product-by-process claims over the prior art.”
Key differences include:
- Focus: Product-by-process claims focus on the end product; method claims focus on the process steps.
- Infringement: Product-by-process claims are infringed by identical products, regardless of how they’re made; method claims are infringed only when the specific steps are performed.
- Examination: Product-by-process claims are examined based on the product structure; method claims are examined based on the specific steps and their order.
Understanding these differences is crucial for proper claim drafting and patent strategy.

A Sequence Identifier (SEQ ID NO) is a unique number assigned to each disclosed nucleic acid and/or amino acid sequence in a patent application. According to MPEP 2422.01:
“37 CFR 1.821(d) and 37 CFR 1.823(a)(5) require that each disclosed nucleic acid and/or amino acid sequence in the application appear separately in the “Sequence Listing”, with each sequence further being assigned a sequence identifier, referred to as “SEQ ID NO:” or the like.“
Key points about Sequence Identifiers:
- They must begin with 1 and increase sequentially by integers.
- Each sequence must have a different number for identification.
- Sequences should be presented in numerical order in the “Sequence Listing” where practical.
- When discussing a sequence in the description or claims, a reference to its SEQ ID NO is required at all occurrences.
- SEQ ID NOs can be used to discuss or claim parts of a sequence (e.g., “residues 14 to 243 of SEQ ID NO:23”).
The use of SEQ ID NOs provides a shorthand way for applicants to discuss and claim their inventions without restricting how an invention can be claimed.
To learn more:
Sequence identifiers (SEQ ID NOs) are crucial in patent applications containing nucleotide and/or amino acid sequences. According to MPEP 2421.02:
- Each disclosed nucleotide and/or amino acid sequence must be assigned a unique SEQ ID NO.
- SEQ ID NOs must be used to identify sequences in the specification, claims, and drawings.
- The SEQ ID NO should be placed adjacent to the sequence or used in a table correlating sequence names with their corresponding SEQ ID NOs.
The MPEP states: “The rules require that the sequence identifiers must be used in all instances where the sequences are disclosed in a patent application.” This ensures clear and consistent referencing of sequences throughout the application.

Cross-noting in patent applications refers to the process of recording and verifying information about prior applications, including U.S. and foreign applications, for which benefit or priority is claimed. This information is typically noted on the bibliographic data (bib-data) sheet of the application and is used to ensure accurate representation of priority claims on the front page of a printed patent.
According to MPEP 202, “The front page of a printed patent identifies all prior applications for which benefits are claimed under 35 U.S.C. 119(e), 120, 121, 365(c), or 386(c) in continuation-in-part, continuation, divisional, and reissue applications.”
The USPTO requires that different matters be submitted in separate papers to avoid confusion and delays. This requirement is outlined in 37 CFR 1.4(c), which states:
Since different matters may be considered by different branches or sections of the Office, each distinct subject, inquiry or order must be contained in a separate paper to avoid confusion and delay in answering papers dealing with different subjects.
Key points to remember:
- Each distinct subject, inquiry, or order should be in a separate paper.
- This applies to both patent and trademark correspondence.
- Exceptions are allowed for subjects provided for on a single Office or World Intellectual Property Organization form.
If you submit multiple subjects in a single paper, the USPTO may use Form Paragraph 5.01.01 to notify you of the requirement for separate papers in future correspondence.
Adhering to this requirement helps ensure that your correspondence is processed efficiently by the appropriate Office branches or sections.

Incorporating by reference in patent applications can have significant impacts:
- It allows applicants to include the content of another document without reproducing it in full.
- The incorporated material becomes part of the application as if it were explicitly included.
- It can provide support for claims and help meet disclosure requirements.
MPEP 211.05 mentions:
An incorporation by reference statement added after an application’s filing date is not effective because no new matter can be added to an application after its filing date (see 35 U.S.C. 132(a)).
This highlights the importance of including incorporation by reference statements at the time of filing to ensure their effectiveness. Applicants should carefully consider what materials to incorporate and ensure they are properly referenced to support their claims and meet disclosure requirements.

Canadian patent agents must meet specific requirements to practice before the USPTO under limited recognition:
- They must be registered and in good standing as a patent agent under Canadian law.
- They must apply for limited recognition to the USPTO Director.
- They can only represent Canadian citizens or residents before the USPTO.
- Their representation is limited to the presentation and prosecution of patent applications of Canadian applicants.
As stated in MPEP 402.01: Canadian patent agents are not required to pass the regular patent bar examination to represent Canadian applicants. They need not seek formal recognition to practice before the Office.

Under the new Sequence Rules, patent applicants must submit sequence listings in a specific format. MPEP 2412.01 states that “an applicant is required to submit sequence data… in eXtensible Markup Language (XML) format.”
This XML file must conform to the requirements specified in 37 CFR 1.831 – 1.834, which in turn reference particular paragraphs of WIPO Standard ST.26. The use of XML format ensures standardization and machine-readability of sequence data across different patent offices worldwide.

A “Sequence Listing” is a separate part of a patent application that contains disclosures of nucleotide and/or amino acid sequences, along with associated information, using a standardized format and symbols. According to MPEP 2421.01, it is required for applications containing disclosures of nucleotide and/or amino acid sequences that fall within the definitions of 37 CFR 1.821(a).
The MPEP states: 37 CFR 1.821(c) requires that applications containing disclosures of nucleotide and/or amino acid sequences that fall within the definitions of 37 CFR 1.821(a) contain, as a separate part, a disclosure of the nucleotide and/or amino acid sequences, and associated information, using the format and symbols that are set forth in 37 CFR 1.822 and 37 CFR 1.823.

35 U.S.C. 102(a)(2) applies to certain patent documents as prior art. The MPEP states:
“U.S. patents, U.S. patent applications published under 35 U.S.C. 122(b), and international patent applications published under the Patent Cooperation Treaty to another are prior art under 35 U.S.C. 102(a)(2) if the effectively filed date of the disclosure of the reference is before the effective filing date of the claimed invention.”
Key points to understand:
- The reference’s effectively filed date must be before the claimed invention’s effective filing date
- The reference can be prior art even if its publication date is after the claimed invention’s effective filing date
- 35 U.S.C. 102(d) determines when subject matter in these documents was “effectively filed”
Exceptions to 102(a)(2) prior art are provided in 35 U.S.C. 102(b)(2), including disclosures of the inventor’s own work and common ownership scenarios.

What is the significance of a power of attorney in patent applications?
A power of attorney is a crucial document in patent applications that authorizes an attorney or agent to act on behalf of the applicant or assignee. According to MPEP 402.04, “A power of attorney may be filed in an individual application, either original or reissue, and in any national stage application.” This document allows the designated representative to make decisions, file documents, and communicate with the USPTO on behalf of the applicant. It’s important to note that the power of attorney must be properly executed and filed to be effective.

What is the significance of the application filing date for new matter in patent applications?
The application filing date is crucial when determining whether content in a patent application constitutes new matter. MPEP 608.04(a) states:
‘Matter not present on the filing date of the application in the specification, claims, or drawings that is added after the application filing date is new matter.’
This means that any information added to the application after the filing date, which was not present in the original specification, claims, or drawings, is considered new matter. This is important because new matter cannot be added to an application without filing a continuation-in-part application.
The filing date serves as a cutoff point for the content that can be included in the application without being considered new matter. Inventors and patent practitioners must ensure that all necessary information is included in the application on or before the filing date to avoid issues with new matter.

Benefit claims in Continued Prosecution Applications (CPAs) have some unique characteristics:
- A CPA automatically includes a specific reference under 35 U.S.C. 120 to the prior application
- No additional amendment to the specification or application data sheet is required to claim benefit
- A CPA is considered to reference every application in the chain with the same application number
- Priority claims under 35 U.S.C. 119(a)-(d) from the parent application automatically carry over to the CPA
The MPEP states: A request for a CPA is the specific reference required by 35 U.S.C. 120 to every application assigned the application number identified in such request. No further amendment to the specification of the CPA nor a reference in the CPA’s application data sheet is required by 35 U.S.C. 120 or 37 CFR 1.78(d) to identify or reference the prior application, as well as any other application assigned the application number of the prior application (e.g., in instances in which a CPA is the last in a chain of CPAs).
It’s important to note that applicants cannot delete benefit claims to certain applications in a chain of CPAs. The MPEP clarifies: Therefore, regardless of whether an application is filed under 37 CFR 1.53(b) or (d), a claim under 35 U.S.C. 120 to the benefit of a CPA is, by operation of 37 CFR 1.53(d)(7) and 37 CFR 1.78(d)(4), a claim to every application assigned the application number of such CPA. In addition, applicants will not be permitted to delete such a benefit claim as to certain applications assigned that application number (e.g., for patent term purposes).
