Introduction
Business method patents have been a contentious area of patent law, particularly in the United States. These patents cover methods of doing business, such as banking, tax compliance, and e-commerce. The patentability of business methods has evolved significantly over the years, influenced by legislative changes, judicial interpretations, and administrative guidelines. This guide provides a comprehensive overview of business method patents, focusing on their patentability and relevant case law.
What is a Business Method Patent?
A business method patent is a type of patent that protects a specific method of doing business. These methods can include various types of activities, such as financial transactions, marketing strategies, and management techniques. The key characteristic of a business method patent is that it pertains to a process or method rather than a physical invention.
Historical Context
The concept of business method patents is not new. However, their recognition and acceptance have fluctuated over time. Initially, business methods were not considered patentable because they were seen as abstract ideas. This perspective began to change in the late 20th century, particularly with the advent of computer technology and the internet, which enabled new types of business methods.
Legislative Framework
Patent Act of 1952
The Patent Act of 1952 is the foundational statute governing patent law in the United States. It defines what constitutes patentable subject matter under 35 U.S.C. § 101, which includes "any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof." However, the Act does not explicitly mention business methods, leading to varying interpretations over time.
America Invents Act (AIA)
The America Invents Act (AIA), enacted in 2011, introduced significant changes to the U.S. patent system. One of the notable provisions is the establishment of the Transitional Program for Covered Business Method (CBM) Patents. This program allows for the review of the validity of business method patents, particularly those related to financial products or services.
Transitional Program for Covered Business Method Patents
The CBM program is designed to provide a post-grant review process for business method patents. It allows third parties to challenge the validity of a business method patent on various grounds, including prior art and patent eligibility. The program is administered by the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (USPTO).

Patentability Criteria
Subject Matter Eligibility
The primary criterion for patentability is subject matter eligibility under 35 U.S.C. § 101. To be patentable, a business method must fall within one of the four statutory categories: process, machine, manufacture, or composition of matter. However, even if a business method fits into one of these categories, it must also meet other requirements, such as novelty, non-obviousness, and utility.
Novelty and Non-Obviousness
Under 35 U.S.C. §§ 102 and 103, a business method must be novel and non-obvious. Novelty means that the method must be new and not previously disclosed in prior art. Non-obviousness means that the method must not be an obvious improvement over existing methods to someone skilled in the relevant field.
Utility
Under 35 U.S.C. § 101, a business method must also be useful. This means that the method must have a specific, substantial, and credible utility. In the context of business methods, this often translates to practical applicability in a business setting.
Judicial Interpretations
State Street Bank & Trust Co. v. Signature Financial Group, Inc. (1998)
The landmark case of State Street Bank & Trust Co. v. Signature Financial Group, Inc., 149 F.3d 1368 (Fed. Cir. 1998), marked a significant shift in the patentability of business methods. The Federal Circuit held that a business method could be patentable if it produced a "useful, concrete, and tangible result." This decision opened the door for a surge in business method patent applications.
Bilski v. Kappos (2010)
In Bilski v. Kappos, 561 U.S. 593 (2010), the Supreme Court revisited the issue of business method patents. The Court rejected the "machine-or-transformation" test as the sole criterion for determining patent eligibility but affirmed that abstract ideas are not patentable. The decision created uncertainty about the patentability of business methods, emphasizing the need for a more nuanced approach.
Alice Corp. v. CLS Bank International (2014)
The Supreme Court's decision in Alice Corp. v. CLS Bank International, 573 U.S. 208 (2014), further clarified the patentability of business methods. The Court established a two-step framework for determining patent eligibility:
- Determine whether the claims are directed to a patent-ineligible concept, such as an abstract idea.
- If so, determine whether the claims contain an "inventive concept" sufficient to transform the abstract idea into a patent-eligible application.
The Alice decision has had a profound impact on business method patents, leading to increased scrutiny and a higher rate of invalidation.

Administrative Guidelines
USPTO Examination Guidelines
The USPTO has issued various guidelines to help examiners determine the patentability of business methods. These guidelines incorporate judicial interpretations and provide a framework for evaluating business method patent applications.
2019 Revised Patent Subject Matter Eligibility Guidance
In 2019, the USPTO issued revised guidelines to provide clarity on subject matter eligibility. The guidelines emphasize the importance of considering the claim as a whole and provide examples of patent-eligible and patent-ineligible claims.

Covered Business Method Review Program
The CBM review program, established under the AIA, provides an administrative mechanism for challenging the validity of business method patents. The program has been instrumental in weeding out weak patents and ensuring that only robust business methods are granted patent protection.

Case Law Analysis
Key Cases
State Street Bank & Trust Co. v. Signature Financial Group, Inc.
The State Street decision was a turning point in the recognition of business method patents. The court's emphasis on a "useful, concrete, and tangible result" provided a broad criterion for patent eligibility, leading to a surge in business method patents.
Bilski v. Kappos
The Bilski decision introduced uncertainty by rejecting the "machine-or-transformation" test as the sole criterion for patent eligibility. The Supreme Court's emphasis on abstract ideas highlighted the need for a more nuanced approach to business method patents.
Alice Corp. v. CLS Bank International
The Alice decision established a two-step framework for determining patent eligibility, significantly impacting the landscape of business method patents. The decision has led to increased scrutiny and a higher rate of invalidation for business method patents.
Impact on Patent Applications
The judicial interpretations in State Street, Bilski, and Alice have had a profound impact on business method patent applications. The broad criterion established in State Street led to a surge in applications, while the subsequent decisions in Bilski and Alice introduced uncertainty and increased scrutiny.
Practical Considerations
Drafting Business Method Patent Applications
When drafting a business method patent application, it is crucial to ensure that the claims are directed to a patent-eligible concept and contain an inventive concept. The application should clearly describe the practical applicability of the method and provide specific examples to demonstrate its utility.
Navigating the CBM Review Process
The CBM review process provides an opportunity to challenge the validity of business method patents. It is essential to understand the grounds for review and gather robust evidence to support the challenge. Engaging experienced patent counsel can be beneficial in navigating the review process.
Conclusion
Business method patents remain a complex and evolving area of patent law. The legislative framework, judicial interpretations, and administrative guidelines collectively shape the patentability of business methods. Understanding these elements is crucial for navigating the landscape of business method patents and ensuring robust patent protection.
