Abstract field of Patent Infringement Cases - Alice Corp. V. CLS Bank (134 S. Ct. 2347 (2014))

In the vast field of patent law, where innovation and legal intricacies intertwine, a few cases have sparked debate and redefined the boundaries of intellectual property like “Alice vs. CLS Bank”. This landmark battle before the United States Supreme Court between Alice Corporation, a visionary tech firm, against one of the largest financial firms CLS Bank International in the patent infringement case raised a fundamental question Can an abstract idea be protected under patent law?

As the case unfolded, it became clear that the outcome would have ever-evolving implications for the future of technological advancements. Let’s navigate through the case and try to understand it better from patent law’s perspective.

Background of the case - Alice vs. CLS Bank

Alice Corporation, an Australian company, held four patents for a computerized method of mitigating settlement risk in financial transactions. The computerized method aimed to reduce settlement risk by providing real-time analysis and facilitating efficient and secure financial transactions. The patents were –

  1. US 5,970,479 filed 1992, issued 1999
  2. US 6,912,510 filed 2000, issued 2005
  3. US 7,149,720 filed 2002, issued 2006
  4. US 7,725,375 filed 2005, issued 2010

CLS Bank argued that Alice’s claims were directed towards an abstract idea and did not meet the requirements for patent eligibility, hence invalid.

Abstract idea - patent

Initially, the case was filed in the United States District Court for the District of Columbia. The district court heard the case and rendered its decision. In this instance, the district court ruled in favor of Alice Corporation, upholding the validity of their patent claims.

However, CLS Bank International appealed the district court’s decision to the United States Court of Appeals for the Federal Circuit (CAFC). The CAFC, which is a specialized appellate court for patent cases, reviewed the district court’s decision.

The CAFC reversed the district court’s decision, declaring Alice Corporation’s patent claims invalid. This decision by the CAFC prompted Alice Corporation to further appeal the case. Following the appellate process, the case was then brought before the United States Supreme Court.

The Alice/Mayo Test

The Supreme Court’s decision in the case, which was issued in 2014, established the two-step test for determining patent eligibility known as the Alice/Mayo test.

The Alice/Mayo test is a two-step framework established by the United States Supreme Court in the case of Alice Corp. v. CLS Bank International (2014) and further clarified in Mayo Collaborative Services v. Prometheus Laboratories, Inc. (2012). This test determines whether patent claims are directed toward patent eligible subject matter or are merely toward abstract ideas, laws of nature, or natural phenomena.

Step 1To determine if the claims are directed towards an abstract idea, law of nature, or natural phenomenon.

The first step of the Alice/Mayo test involves analyzing the patent claims to determine if they are directed towards one of the judicially recognized exceptions to patent eligibility, such as abstract ideas, laws of nature, or natural phenomena. If the claims are found to fall within these categories, they must undergo further analysis in step 2.

Abstract ideas refer to concepts or principles that are general and not tied to a specific application or technology. Examples of abstract ideas include fundamental economic practices, mathematical algorithms, and mental processes.

Step 2 – To determine if the claims include additional elements that amount to something significantly more than the abstract idea itself.

If the claims are determined to be directed towards an abstract idea, the analysis proceeds to the second step of the Alice/Mayo test. In this step, the focus is on whether the claims include additional elements that go beyond the abstract idea itself and transform it into a patent-eligible invention.

What was the purpose of Alice/Mayo Test?

The goal of the Alice/Mayo test is to achieve a balance between promoting innovation and avoiding the monopoly of essential concepts or natural phenomena. It makes sure that actual inventions that significantly advance technology are granted patents rather than simple or abstract ideas that belong in the public domain.

By creating this standard, the Supreme Court provided guidance to lower courts and the USPTO in determining whether claims in developing technological fields were eligible for patent protection, where the distinction between abstract concepts and patentable subject matter can be cloudy. The Alice/Mayo test has generally had a substantial impact on patent law, influencing the criteria for patent eligibility and influencing the examination and litigation of patents pertaining to software, business techniques, and other areas.

The Supreme court unanimously invalidated the patent, with Justice Clarence Thomas delivering the opinion. According to the Court’s ruling, an abstract idea implemented on a computer cannot be patented. The decision established a two-step analysis to determine patent eligibility, where the court examines whether the claim contains an abstract idea and assesses whether the patent application adds an inventive concept to the idea. The Court clarified that the mere implementation of an abstract idea on a computer, without an inventive element, does not qualify for a patent.
