Cloud Computing Patents

Cloud computing patents are internet-based computing inventions that provide people with the ability to utilize shared computer processing resources. Thus, those cloud users can store data on a variety of software applications that are shared with others. Such cloud computing can be a great benefit to businesses depending on the company’s size, industry, and goals. Such benefits can include lower costs, easier maintenance, added flexibility, and improved IT security. Some of the most popular examples of cloud computing services include IBM, Google, and Amazon Web Services.

Patent Eligibility in Cloud Computing

Determining whether a cloud computing invention qualifies for a patent involves meeting the same criteria as other technological fields: novelty, non-obviousness, and usefulness. However, cloud-related patents often face heightened scrutiny because many claims can appear abstract or too broad. For instance, patents that simply cover “storing data online” are often rejected. Instead, inventors must demonstrate a specific technical solution, such as methods for load balancing, reducing latency, or ensuring secure multi-tenant environments.

Patent examiners frequently apply the Alice/Mayo test, which evaluates whether a claim is directed to an abstract idea and, if so, whether it includes an inventive concept that transforms it into a patent-eligible invention. Cloud patent applicants must therefore frame their claims around technical innovations rather than business concepts.

Risks of Cloud Computing

With the above-mentioned benefits in mind, there is also great risk when using the cloud to store and maintain data. But a lot of businesses, and generally speaking, the public, aren’t aware of such risks, or the risks simply go overlooked. Storing patent information on the cloud could be a benefit for Patent Assertion Entities (“PAEs”), which are businesses that acquire patents from third parties and subsequently seek to generate revenue by asserting them against supposed infringers.

  • PAEs generally store countless patents on the cloud, usually vague and/or broad patents, for the purpose of suing companies on the grounds of patent infringement in order to earn compensatory damages and/or ongoing royalty payments.
  • The reason PAEs do this is because it is easy to find infringers by utilizing codes for open source, thus making the cloud an easy target.
  • PAEs then target cloud customers as customers don’t usually have the same level of knowledge as cloud service providers and are less prepared to defend a patent infringement suit.

Patent Assertion and Litigation Trends

Litigation in the patent cloud space has surged as companies increasingly rely on third-party providers. Patent Assertion Entities (PAEs) often target end users of cloud services, creating a “double risk” for businesses that lack the legal or technical resources to defend against claims. Large tech companies, meanwhile, are engaged in patent wars, building massive portfolios not only to protect their technology but also to negotiate cross-licensing agreements.

Some common areas of dispute include:

  • Virtualization technologies that allow multiple users to share hardware.
  • Data migration and synchronization methods across different cloud platforms.
  • Security protocols for encrypted cloud storage.
  • Resource allocation algorithms for efficient processing.

This environment makes freedom-to-operate (FTO) searches critical before deploying new cloud-based solutions. Businesses must ensure their services do not inadvertently infringe on patents held by competitors or PAEs.

Enforcement of Cloud Computing Infringement

Since there is no such thing as an international patent, PAEs cannot file an infringement claim in one country  (the U.S.) and receive compensatory relief for a patent that is protected in another country, i.e. Europe. Therefore, if the PAE wants to go after the alleged infringer, then it will need to file claims in any country in which the product is being used. For strategically important patents, they are always part of a patent family that are granted by several countries. The IFI Claims Service examines the geographical distribution of companies that are assigned U.S. patents. The top 5 countries include:

  • United States – 41%
  • Japan – 28%
  • Korea – 15%
  • Taiwan – 4%
  • Germany – 3%

Based on the significant difference between U.S. patents (167 in total) and the total number of patent families worldwide (1,616 in total), it’s clear that a majority of strategically important patents are being filed outside of the U.S., which is where a lot of infringement cases are brought. For example, Switzerland is a common jurisdiction for enforcement, as it is a party to many international IP treaties. Recognition of foreign arbitral awards usually holds merit in the Swiss Federal Supreme Court, as the court has a narrow interpretation of public policy and generally hesitates to re-examine the merits of foreign arbitral awards.

International Patent Strategies for Cloud Technologies

Because patent protection is jurisdiction-specific, companies that operate global cloud platforms must adopt international filing strategies. Many file under the Patent Cooperation Treaty (PCT) to streamline applications in multiple countries. Tech companies typically prioritize jurisdictions with high cloud adoption, such as the United States, Europe, China, and Japan, to secure strong enforcement options.

Another strategic tool is defensive patenting—acquiring patents not necessarily to commercialize, but to deter lawsuits or to use as leverage in cross-licensing negotiations. Major providers like Amazon, Microsoft, and Google actively use these strategies to strengthen their positions in the global market.

A Prime Example of How Cloud Computing Can Be Protected: IBM

Over the past year and a half, IBM has obtained 1,200 patents on cloud computing. Its patents are more general in nature, specifically general cloud processes or operations that other service providers already use. For that reason, IBM’s patent library may be used to demand royalty payments or other monetary relief if others hold a patent on it. However, based on the U.S. Patent and Trademark Office’s issuance of Patent 8,949,415, a business operating in the cloud computing space can conserve network bandwidth by conducting a network disablement action. Thus, businesses can use secure data and deploy secured data to one or more secure servers, thereby reducing what is left on the cloud. Other patent issuances by the USPTO provide safety measures for businesses operating in the cloud computing industry and storing such important and confidential data on the cloud.

Emerging Trends in Patent Cloud Innovation

The cloud computing landscape is rapidly evolving, and patent strategies are adapting with it. Some notable trends include:

  • AI-driven cloud services: Patents increasingly focus on integrating artificial intelligence for predictive analytics, security monitoring, and automated scaling.
  • Hybrid and multi-cloud models: Innovations that allow seamless movement of workloads across private and public clouds are becoming heavily patented.
  • Green cloud computing: Patents are emerging around energy-efficient data centers and carbon-aware workload allocation.
  • Edge computing integration: Protecting inventions that extend cloud capabilities closer to users, improving latency and efficiency.

These advancements highlight how the patent cloud ecosystem is becoming more competitive and complex, with companies racing to secure intellectual property that defines the future of digital infrastructure.
