This article examines the systemic impact of economic digitalization, cloud computing, and artificial intelligence on the classical principle of territoriality in patent rights protection. The authors analyze doctrinal approaches to resolving jurisdictional conflicts and qualifying cross-border infringements within the distributed nature of utilizing inventions. Based on international legal agreements (the Paris Convention, the TRIPS Agreement), as well as current judicial and arbitral practice (including the WIPO Arbitration and Mediation Center), the study substantiates the growing role of international commercial arbitration as the most flexible and economically oriented mechanism for resolving such transboundary disputes.

If we consider the impact of AI and cloud computing on the economy, it immediately becomes clear that conventional notions of borders are no longer viable. Across the globe, intellectual products are utilized simultaneously across multiple jurisdictions, effectively disregarding national boundaries. The digital economy has given rise to decentralized, distributed processes entirely detached from any specific physical territory. Ultimately, this reality challenges the stability of the foundational principles of international patent law, which appear increasingly vulnerable under modern conditions [1].

One such fundamental tenet is the principle of territoriality, under which patent rights are enforceable exclusively within the borders of the state that granted protection [2]. For a long time, this principle ensured a tight nexus between a legal relationship and a specific country, which to some extent simplified the determination of unauthorized use. However, as these technologies are deployed, this aspect has taken on a more blurred and ambiguous form [3].

Scenarios where elements of a single technological process are distributed across several countries introduce distinct complexities. They prompt further debate regarding what constitutes the "use" of an invention and which specific country should be recognized as the forum where patent law infringement occurred [4]. Legal uncertainty and the provocation of jurisdictional conflicts can be exacerbated in the absence of a concrete response to the aforementioned actions.

The territoriality provision serves as a core element of the international patent protection framework, wherein the legal protection of an invention is strictly limited to the borders of the state where the patent was issued [1]. In contrast to other fields of law where the unification of legal provisions is highly feasible, patent law retains its inherently national character. This is particularly evident regarding the issuance of a patent, which directly correlates to a specific state’s sovereign decision to recognize an invention as meeting defined patentability criteria [6].

The Paris Convention explicitly establishes the independence of patents and remains one of the pivotal agreements in this field. Additionally, the TRIPS Agreement sets forth minimum standards of legal protection without overriding the national specificity of these rights [2]. Under contemporary conditions, a patent is viewed as a bundle of national rights rather than a single global title.

In this context, when discussing the legal ramifications of applying the principle of territoriality, it is crucial to note that enforcement certainty is a vital element in defining the scope of application, jurisdiction, and liability for infringement [3]. Within the traditional model of intellectual property rights infringement, the violation occurs in the country where the IP asset is used without the right holder's consent, which provides a predictable legal framework for the infringing party to assess risks associated with the breach.

Legal doctrine dictates that this principle has never truly existed in a "pure" form. With the evolution of digital technologies, situations have increasingly arisen where the constituent elements of an infringement are scattered across different jurisdictions. In particular, the domestic laws of certain states allow for the interpretation of the territoriality principle through the lens of the "extraterritorial effects" doctrine, whereby actions taken outside state borders may be taken into account if they produce an effect on the domestic market [10]. However, these approaches do not form a unified international standard.

The category of "use of an invention" lies at the very heart of the framework when analyzing patent infringement issues. Consolidating manufacturing, use, offering for sale, sale, and importation of a patented product—or the application of a patented process [6]—this category encompasses actions that traditionally have a tangible, material expression and lend themselves to precise localization. These actions carry a traditionally material manifestation and can be localized, thereby enabling the application of the territoriality principle.

It is equally necessary to recognize the distinction between product patents and process patents. First, a product patent infringement presupposes the unauthorized use of a physical object, whereas in a process patent, the key element is the execution of the process itself. Although modern processes are generally intangible, legal doctrine remains grounded in the thesis that all activity, in essence, materializes in some shape or form. Activity is presumed to be inextricably linked to physical objects, whether industrial machinery or manufacturing components.

With the growth of international trade and digital technologies, however, this assumption is beginning to lose its universal character. Early 21st-century doctrine emphasized that the use of an invention can acquire a "distributed character," wherein various stages of its execution can be carried out across different states [11]. This raises the question of whether each stage should be scrutinized in isolation, or whether every stage must be evaluated as an independent act of unauthorized use.

The digitalization of the economy has led to a radical overhaul of traditional approaches to determining territoriality in patent law. While the use of an invention was tightly bound to a specific physical territory in the classical model, this connection is becoming increasingly nominal under the conditions of cloud computing and artificial intelligence. Modern technological processes are characterized by a high degree of distribution: computations are performed on servers located in different countries, data moves between jurisdictions in real time, and users can interact with a technology without any awareness of its actual physical location [14]. This creates a scenario where traditional criteria for determining the place of an invention's use prove inapplicable.

The qualification of cross-border infringements presents a particular challenge, where different elements of a single technological process are executed in different states. For instance, the training of an artificial intelligence model might occur on servers in one country, its deployment in another, and its end-use in a third. Under such circumstances, a fundamental question arises: should each stage be viewed as an independent use of the invention, or is it necessary to evaluate the process in its entirety as a single, unified infringement [13]? The lack of a uniform approach to resolving this matter leads to legal uncertainty and escalates the risk of jurisdictional conflicts.

Judicial practice demonstrates attempts to adapt to these new realities; however, such attempts remain fragmentary and often contradictory. In Microsoft Corp. v. AT&T Corp., the US Supreme Court adopted a formalistic territorial approach, refusing to extend the reach of patent law to software transmitted outside the country [16]. Conversely, in the later case of WesternGeco LLC v. ION Geophysical Corp., the Court allowed for the recovery of damages for actions partially performed abroad, provided they had a substantial economic effect within the territory of the United States [17]. These decisions illustrate a gradual shift away from a strict territorial approach toward a more flexible, economically oriented interpretation of patent law.

Amidst the growing complexity of cross-border disputes, international commercial arbitration is becoming an increasingly sought-after mechanism for their resolution. Its key advantage lies in its capacity to consider the economic substance of the dispute and to approach the determination of the applicable law with flexibility. In the practice of arbitral institutions—specifically the WIPO Arbitration and Mediation Center—there is a noticeable trend away from the formalistic analysis of where actions were committed in favor of evaluating the aggregate effect of the technology's use and its nexus to specific markets [13]. Nevertheless, the capabilities of arbitration remain constrained because it cannot bypass the national nature of patent rights, and issues concerning patent validity continue to fall within the exclusive jurisdiction of state courts [6].

Modern doctrine offers several approaches to overcoming the territoriality crisis. One is the concept of economic effect, according to which the turning factor is not the location where individual operations are executed, but rather the territory where the primary commercial result of the invention's use materializes [3]. This approach makes it possible to account for the real consequences of an infringement, yet its application carries the risk of overextending jurisdiction and causing conflicts between states. Another direction is the functional approach, which entails analyzing a distributed technological process as a single whole, irrespective of the geographic allocation of its individual components [7]. This approach more adequately reflects the specifics of digital technologies, but it demands a substantial transformation of traditional legal categories.

Additionally, academic literature and policy documents increasingly raise the need to rethink the role of data as a key asset of the digital economy. In the context of artificial intelligence, data becomes an organic part of the technological process, and its cross-border movement complicates the determination of jurisdiction and applicable law [14]. In this regard, models oriented toward analyzing data flows and their economic significance are being proposed, indicating a gradual shift in focus from geographic criteria to functional and economic parameters.

International organizations also recognize the necessity of adapting legal regulation to digital realities. The World Intellectual Property Organization points to the need to develop new approaches to regulating intellectual property in the face of widespread artificial intelligence [13]. The Organisation for Economic Co-operation and Development emphasizes the cross-border nature of digital technologies and the necessity for coordinated international solutions [14]. The European Union, for its part, is actively developing a regulatory framework for artificial intelligence, including proposals to regulate its use and liability for caused harm [15]. These initiatives bear witness to the formation of a new stage in the evolution of international law, within which territoriality is gradually yielding to more flexible and comprehensive regulatory models.

The analysis conducted allows us to state that the digital transformation of the economy exerts a systemic impact on the baseline principles of patent law, most notably the principle of territoriality. Historically, this principle ensured a clear attribution of exclusive rights to a specific state jurisdiction and served as the foundation for determining the applicable law and the competent dispute resolution body. However, against the backdrop of cloud computing and AI development, the use of inventions acquires a distributed and transnational character, rendering traditional criteria of territorial localization less and less applicable.

Under these conditions, international commercial arbitration takes on special significance as a more flexible mechanism for resolving cross-border disputes. The ability to select the applicable law and the orientation toward the economic substance of the dispute allow arbitration to partially offset the shortcomings of the traditional territorial model. At the same time, its potential is limited by the national nature of patent rights and the impossibility of adjudicating issues of their validity outside the framework of state jurisdiction.

An analysis of contemporary academic, political, and legal approaches indicates the emergence of a transitional regulatory model. Within this model, a gradual departure from a rigidly geographical understanding of territoriality toward functional and economic criteria is taking place. The concepts of economic effect, functional analysis, and data flow tracking reflect an ambition to adapt the legal system to the realities of the digital economy; however, their practical application requires further theoretical refinement and institutional consolidation.
