The Power of Open Standards: How the Nordic Innovation Model Continues in the 6G Era, as Seen from the Rise of InterDigital

Opening: How Did a Company with No Products Become the Biggest Winner in 5G?

In the field of mobile communications, InterDigital stands out as a special case: it does not manufacture any hardware, yet it has reaped astonishing gains from the 5G wave. Since 2020, its annual revenue has grown by 132%, reaching $834 million by 2025; its stock price has surged 274% over five years, far outpacing competitors such as Qualcomm (33%), Ericsson (-2%), and Nokia (144%). Behind this phenomenon lies a deeper narrative: the value of global unified mobile communication standards and the critical role of the Nordic innovation system in this process.

InterDigital CEO Liren Chen attributes the company's success to a focus on fundamental research—investing 30%–40% of recurring revenue in R&D each year and accumulating around 40,000 patents. But what truly makes this model work is the single global standard that the mobile communications industry has gradually established since 2G. And it is the Nordic countries—especially Sweden's Ericsson and Finland's Nokia—that have been the core drivers of this standardization process.

Background: InterDigital's "China Miracle" and Patent Games

According to Light Reading, before 2020 InterDigital had tense relations with Chinese manufacturers and was involved in litigation with Huawei. But since Chen took over as CEO in 2021, through collaboration and licensing enforcement, the company has brought most major Chinese handset makers (Honor, OPPO, vivo, Xiaomi, ZTE, etc.) into its licensing customer base. Annual revenue from Chinese companies surged from $63.2 million in 2020 to $309.3 million in 2025, making China its largest source of revenue. Today, InterDigital has licensing agreements covering 85% of the global smartphone market, with annualized recurring revenue growing from about $300 million to nearly $500 million.

It should be emphasized that this growth does not rely on product competition but on the value of its patent portfolio. In LexisNexis' 2025 Patent Asset Index ranking, InterDigital ranks seventh globally, behind only giants such as Huawei, Qualcomm, and Samsung, and even surpassing Nokia. This proves that even with a relatively limited R&D budget (about $211 million in 2025), a patent holder focused on fundamental research can secure a favorable position in the standard essential patent (SEP) arena.

Deeper Logic: Why Standardization Amplifies Innovation?

InterDigital's success ultimately stems from the existence of a global unified standard. The CEO clearly points out that without a unified standard, Chinese handset manufacturers would not be able to rapidly rise using the global supply chain. Standardization lowers the cost of spreading innovation, allowing technology contributors to obtain returns through patent licensing based on fair, transparent, and non-discriminatory (FRAND) principles. This mechanism encourages companies to undertake high-risk fundamental research, because patents can be widely adopted across the entire industry.

This logic is highly aligned with the Nordic innovation system.This logic aligns closely with the Nordic innovation system. Nordic countries (especially Sweden and Finland) have historically played a leading role in mobile communication standard setting—Ericsson and Nokia are not only standard contributors but also strong advocates of open standards. They benefit from an internal education system and social trust, driving an ecosystem of industry-academia collaboration that enables rapid translation of basic research results into industry-wide general-purpose technologies. For example, Nokia, Ericsson, and several Nordic universities have established long-term collaborative projects on 6G research (such as Finland's 6G Flagship), focusing on fundamental physical layer, network architecture, and AI-native design.

Understanding the Nordic System: Openness, Trust, and Long-Termism

One of the core features of the Nordic model is social trust and transparent collaboration. In mobile communications, this is manifested in enterprises, research institutions, and governments jointly participating in international standard organizations (such as 3GPP) and adhering to FRAND commitments. The Nordic education system emphasizes cultivating interdisciplinary skills and critical thinking, enabling researchers to engage in cutting-edge exploration while understanding commercial applications. Moreover, Nordic countries support long-term basic research through public funding (e.g., Vinnova in Sweden, the Academy of Finland), reducing enterprises' dependence on short-term returns.

Although InterDigital's case comes from the United States, its success precisely validates the standardization logic promoted by the Nordics: when the entire industry follows uniform rules, even non-manufacturers can profit from innovation. Conversely, Nordic companies (such as Nokia and Ericsson) still rank high in 5G patent rankings (Nokia 8th, Ericsson 5th), thanks to their sustained investment in basic technology and standardization.

Notably, InterDigital's current patent family ranking (19th) is lower than its asset index ranking, indicating that its patent quality outweighs quantity. This reflects the Nordic innovation system's emphasis on "quality over quantity"—Ericsson and Nokia also stress strategic value rather than sheer numbers in their patent portfolios. For example, through its acquisition of Alcatel-Lucent and R&D investment, Nokia has accumulated high-impact patents in 5G core networks and optical networking.

Global Significance: Challenges in the 6G Era and the Reference Value of the Nordic Model

The transition to 6G (expected to be commercially available around 2030) may introduce new variables. InterDigital's CEO explicitly hopes that the world will continue to adhere to a single unified standard and points out that no vendor is truly promoting an alternative waveform (OFDM remains the foundation of 4G/5G). However, geopolitical risks, emerging technologies (such as AI-native architecture, terahertz communications), and new entrants (such as satellite operators) may increase the pressure of standard fragmentation.The Nordic open model provides an important reference for the world: maintaining unified standards through multilateral cooperation while encouraging regional innovation labs to explore cutting-edge technologies. For example, Sweden's "6G Research Program" and Finland's "6G Flagship" are jointly funded by governments, enterprises, and academia, studying future network architectures oriented toward 2030, with emphasis on sustainability, security, and digital inclusion. These projects focus not only on technical indicators but also incorporate Nordic social values—such as privacy protection and green communications (with a target of 90% energy consumption reduction).

For other countries (especially China, the U.S., and the EU), the InterDigital story reveals a key fact: basic research investment and patent strategy must be deeply integrated with the global standardization process. A mere technological breakthrough, if not adopted by standards, will see its commercial value greatly diminished. The Nordic model of industry-academia collaboration, patent pool management experience, and FRAND implementation oversight system deserves in-depth study by policymakers.

Long-term Trend Judgment: 6G Will Expand the Boundaries of Patent Licensing

InterDigital has already set its sights on new device forms that 6G may enable (such as IoT, wearable devices, and mixed reality glasses). Its wireless IoT business annual revenue has grown from approximately $20 million to $80 million, with a target of reaching $200 million by 2030. More importantly, it is licensing video compression technology to cloud service providers (such as Amazon Prime and Disney+), aiming to achieve $300 million in revenue by 2030. This indicates that the boundaries of patent licensing in the 6G era will expand from smartphones to a broader digital ecosystem.

Nordic companies are also actively positioning themselves for 6G patents. In 2025, Nokia announced a shift in its R&D focus toward AI-driven networks, cloud-native core networks, and sustainable communications. Ericsson emphasizes that 6G must achieve "intelligent, trustworthy, and green," and its patent strategy will focus on new air interface design and spectrum sharing technologies. It is foreseeable that the 6G patent landscape will continue the concentration seen in 5G, but the position of Chinese companies (Huawei, ZTE) may further improve, while Nordic companies will maintain a core position based on long-term R&D accumulation.

Conclusion

InterDigital's rise is not an isolated case but a testament to the superiority of the global mobile communications standardization system. Through open innovation, social trust, and a long-term perspective, Nordic countries have laid an irreplaceable foundation for this system. Looking toward 6G, the Nordic model will continue to provide experience: only by persistently investing in basic research, maintaining unified standards, and embracing cross-border cooperation can the full potential of technology be truly unleashed. For observers, focusing on the innovation ecosystem behind patent rankings is more meaningful than watching stock price fluctuations.
