The United States Supreme Court recently declined certiorari to hear two cases, Tropp v. Travel Sentry, Inc. and Interactive Wearables, LLC v. Polar Electro Oy, that could have significantly shaped the future of patent law. Originally, the prospect of the Court hearing these cases had opened the possibility of addressing whether claimed inventions are ineligible for patent protection under the “abstract-idea” exception to Section 101.

These cases were seen as potential opportunities to clarify the contentious issue of patent eligibility under 35 U.S.C. § 101, a topic that has been steeped in confusion and disagreement in recent years. However, the Supreme Court's decision to deny cert for both cases, despite each addressing a unique type of invention, indicates its current reticence to provide further clarity on the interpretation of the ‘abstract idea’ exception under U.S. patent law.

The implications of this denial could be far-reaching. Inventors, businesses, and various stakeholders across a multitude of industries, most notably in the software and life sciences sectors, were looking towards these cases in hopes of greater certainty. The Supreme Court's denial, however, maintains the status quo, leaving the issue of the “abstract-idea” exception and patent eligibility with no immediate resolution.

Patent Eligibility Background

Patent law functions as a vital pillar of innovation, granting inventors exclusive rights to their inventions as a means of stimulating scientific progress and economic development. Central to this legal framework is Section 101 of the U.S. patent law, which dictates the types of inventions that can receive patent protection. This provision allows patents for “any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof.”

However, the Courts have recognized certain exceptions to this rule, specifically laws of nature, physical phenomena, and abstract ideas. While the first two exceptions are generally well-defined, the ‘abstract idea’ exception has proven to be a persistent challenge, leading to varied interpretations and subsequent confusion within the patent system. The Supreme Court has previously issued opinions in Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 573 U.S. 208 (2014) and Mayo Collaborative Servs. v. Prometheus Labs., Inc., 566 U.S. 66 (2012) that set forth a two-step framework for considering subject matter eligibility. The two step “Alice/Mayo” framework involves first determining whether the claims at issue are directed to a patent-ineligible concept such as an abstract idea, and if so, considering the elements of the claims individually and as an ordered combination to see if they transform the nature of the claim into a patent-eligible application.

In recent years, the Federal Circuit has shown significant disagreement over the application of Section 101, primarily stemming from the challenge of interpreting and applying the “abstract idea” exception, one of the judicially created exceptions to patent eligibility. The Supreme Court has not provided a clear definition of what constitutes an “abstract idea,” resulting in diverse interpretations by the Federal Circuit. For example, in International Business Machines Corp. v. Zillow Group, Inc., Weisner v. Google LLC, and others, the Federal Circuit was deeply divided over the application of the two-step Alice/Mayo framework that the Supreme Court has established to determine patent eligibility under Section 101. 

The Federal Circuit often describes technological inventions at a high level of abstraction when determining whether they are directed to an abstract idea. This approach has been controversial because it can make almost any invention seem like an abstract idea, potentially excluding many technological inventions from patent protection. Furthermore, the Federal Circuit has been accused of improperly introducing considerations from other areas of patent law, such as novelty and non-obviousness, into the Section 101 analysis. Judges have disagreed about whether this is appropriate or whether it conflates distinct legal standards.

For example, in the case of American Axle & Manufacturing, Inc. v. Neapco Holdings LLC, 939 F.3d 1355 (Fed. Cir. 2019), one of the judges accused the majority of granting Section 101 a new superpower – “enablement on steroids.” This was a criticism of the way the majority had allegedly imported standards from the doctrine of enablement (which requires the patent application to describe how to make and use the invention) into the Section 101 analysis. The ambiguity surrounding the ‘abstract idea’ exception is exemplified in the Federal Circuit’s inconsistent application of the Supreme Court’s two-step framework established in Alice Corp. v. CLS Bank International. It’s been observed that the Federal Circuit often describes technological inventions in broad terms when invoking the abstract-idea exception, which has been a source of confusion.

Likewise, the U.S. Patent and Trademark Office (USPTO) has struggled to consistently apply the Court’s Section 101 precedents. Despite attempts to make the application of judicial precedents more uniform, such as the 2019 Revised Patent Subject Matter Eligibility Guidance, the agency has admitted that it is challenging to predictably determine what subject matter is patent-eligible. This has raised concerns among inventors, businesses, and other patent stakeholders and has presented unique challenges for the USPTO itself.

The Supreme Court's recent decision to deny certiorari in Tropp v. Travel Sentry, Inc. and Interactive Wearables, LLC v. Polar Electro Oy significantly leaves several of these aspects unresolved. These cases had been viewed as an opportunity for the Court to clarify the scope of the abstract idea exception, determining which types of inventions it encompasses. Additionally, it was anticipated that the Court might elucidate how its two-step framework for assessing patent eligibility relates to other patent doctrines such as novelty, obviousness, and enablement. A decision to hear these cases might have provided guidance as to (1) determining an appropriate level of generality at which to evaluate whether an invention falls within the realm of an abstract idea and (2) the propriety and degree of importing other patent-law doctrines into the analysis of abstract ideas. With the Supreme Court's denial, however, these key issues remain largely unresolved, leaving the patent law community in continued anticipation of future guidance.

Interactive Wearables, LLC v. Polar Electro Oy

Interactive Wearables, LLC v. Polar Electro Oy, No. 2021-1491 (Fed. Cir. Oct. 14, 2021), involves a patented technology (U.S. Patent Nos. 9,668,016 and 10,264,311) related to a wearable content player with a remote-control device. The remote control is wirelessly connected to the content player and features a second display to present to the user at least a portion of the information associated with the content. Despite not falling under the traditional umbrella of an “abstract idea,” the patent was invalidated by the Federal Circuit for lack of patent eligibility under Section 101, concluding that the invention was merely an abstract idea of providing information in conjunction with media content. 

The Federal Circuit’s decision raises several questions about the interpretation and application of Section 101. Firstly, it demonstrates the court’s inclination to describe technological inventions at a high level of generality when assessing whether they are directed to an abstract idea. The court’s decision to invalidate Interactive Wearables’ patent, for instance, has been criticized for being overly broad in its interpretation of what constitutes an abstract idea, thus effectively broadening the range of inventions that could potentially be deemed ineligible for patent protection.  Secondly, the case reveals a tendency for the court to import distinct patent-law doctrines into the abstract-idea analysis. This tendency has been contested as it arguably blurs the line between different aspects of patent law, such as novelty and patent eligibility, and can create confusion in the application of these different doctrines.

The decision in the Interactive Wearables case is also indicative of the challenges faced by the U.S. Patent and Trademark Office (USPTO) in applying the Supreme Court’s Section 101 precedents consistently. Despite the USPTO issuing guidance in 2019 to make the application of judicial precedents more consistent, the agency has admitted that applying the recent Section 101 decisions “in a consistent manner has proven to be difficult” and has caused uncertainty in this area of the law. This uncertainty, as highlighted by the Interactive Wearables case, makes it difficult for inventors, businesses, and other patent stakeholders to reliably and predictably determine what subject matter is patent-eligible.

Following the denial of certiorari, the USPTO and Federal Circuit retain the latitude, at least for the moment, to pursue analyses that potentially oversimplify the technological functions of claimed inventions and frame them with a high degree of generality.

Tropp v. Travel Sentry, Inc.

Tropp v. Travel Sentry, Inc., No. 2021-1908 (Fed. Cir. Feb. 14, 2022), revolves around a dispute over U.S. Patent Nos. 7,021,537 and 7,036,728, owned by David Tropp.  These patents involve screening luggage without breaking locks, developed in response to the post-9/11 TSA policy of inspecting all checked luggage. Tropp’s solution was a dual-access lock, which could be opened by the owner or by a master key held by screening agents, thereby ensuring security without damaging passengers’ belongings. The patents were contested by Travel Sentry, an industry rival, which sought a declaratory judgment of non-infringement and invalidity of Tropp’s patents. Travel Sentry implemented a similar lock-and-master-key program.

The District Court for the Eastern District of New York, after over a decade of litigation, ruled Tropp’s patents to be patent-ineligible abstract subject matter under 35 U.S.C. § 101, seeing them as an “application of dual-access locks to airport luggage inspection,” a long-standing practice. The court dismissed Tropp’s argument that his patents enabled an entirely new process, arguing they were merely a combination of existing practices. Tropp appealed to the Federal Circuit, arguing that his patents were not directed at an ineligible concept but represented an inventive concept that transformed them into patent-eligible applications. However, the Federal Circuit affirmed the District Court’s decision, citing that the patent claims were an abstract idea directed to a “longstanding fundamental economic practice and method of organizing human activity.”

Tropp’s invention, although physical in nature, was assessed in the context of the abstract-idea exception, which traditionally pertains to concepts such as mathematical formulas, economic practices, or methods of organizing human activities.

In Interactive Wearables, the Federal Circuit’s application of the abstract-idea exception has been criticized for describing technological inventions at a high level of generality, potentially undermining innovative ideas. On the other hand, Tropp focused on a claim that has been deemed an abstract idea, involving the coordination between passengers and the Transportation Security Administration (TSA) to minimize luggage lock breakages. These cases highlighted the need for clarity in determining the boundaries of patent eligibility when it comes to technological and non-technological concepts.

With the Supreme Court's denial of certiorari in these cases, the questions surrounding the inconsistent application of Section 101 patent eligibility remain unanswered. These cases underscore the ongoing debate about the application of the abstract-idea exception, particularly in relation to technological inventions. Current interpretations might risk being overly broad and generalized, potentially undermining innovation. Furthermore, the issue of whether other patent-law doctrines have been improperly imported into the abstract-idea analysis continues to be a matter of contention. The clarification and simplification of Alice’s two-step framework, a central aim in these appeals, now remains a task for future cases. It remains critical to ensure that inventive and valuable patents are not incorrectly classified as abstract ideas, as this could hamper innovation. As it stands, the application of Alice’s framework in assessing the patent eligibility of tangible innovations still requires further clarity.

The Supreme Court's denial of certiorari in these cases leaves unresolved the issues surrounding inconsistent application of Section 101 patent eligibility and the scope of the abstract-idea exception, particularly for technological inventions. The decisions defer the anticipated clarification of Alice’s two-step framework and the differentiation between patent-eligible and patent-ineligible subject matter. As a result, ambiguity persists, underscoring the need for future guidance to ensure consistency in patent eligibility decisions and to safeguard innovation from potentially overly broad interpretations of the abstract-idea exception.

Potential Impact on Future Patents

A more precise and comprehensive standard for patent eligibility under Section 101 remains necessary for inventors, businesses, and other patent stakeholders. With the Court not yet having tackled the scope of the judicial exception, a significant decision by either the Federal Circuit sitting en banc or by Congress may be anticipated. Such a decision could significantly shape future patents, particularly within software and life sciences fields.

A refined interpretation of the abstract-idea exception could bolster the protection of technological innovations, instilling inventors with the confidence to pursue patent protection for their novel and useful inventions. Such refinement could also elucidate the unique nature of patent eligibility, setting it apart from other patentability considerations like obviousness and enablement. As the task now falls to the Federal Circuit or Congress, it remains to be seen how either entity will balance fostering innovation with defining the limits of patent eligibility in the future.
