The role of open patent pools in accelerating Electric Vehicle (EV) innovation is significant, as they facilitate collaboration and reduce barriers to technology access. By pooling patents, companies can share complementary technologies such as Internet of Things (IoT), Artificial Intelligence (AI) and blockchain, when combined with 5G, create opportunities to enhance digital experience, improve performance, data security and enable continuous operations, which enhances product quality and variety while minimizing licensing disputes. This collaborative approach can increase innovation rates and a more efficient development process.
The EV industry stands at the crossroads of innovation and sustainability, redefining global transportation. With advancements in battery technologies, autonomous driving systems, and renewable energy integration, the sector is rapidly evolving. However, the path to innovation is riddled with challenges, especially in navigating the complex landscape of intellectual property (IP).
The open patent pools, a transformative approach that democratizes access to cutting-edge technologies, reduces litigation risks, and accelerates collaboration. In the EV industry, where innovation thrives on interoperability (i.e., seamlessly exchanging and using information) and standardization, patent pools are paving the way for an unprecedented era of progress. This article explores the role of open patent pools in shaping the future of EVs, emphasizing their impact on innovation, challenges, and the opportunities they create for stakeholders.
Open patent pools and Standard-Essential Patents (SEPs) are revolutionizing EV innovation by making critical technologies more accessible. By licensing on fair terms, they reduce legal friction and enable faster industry-wide adoption. Tesla’s 2014 decision to open its EV patents illustrated how sharing IP can spark collaboration and accelerate progress. Today, both startups and major EV manufacturers benefit from this shift toward openness and interoperability.
Understanding Open Patent Pools
At its core, a patent pool is where multiple patent holders agree to license their technologies under standardized terms. Unlike traditional licensing models, open patent pools prioritize accessibility, ensuring that innovations are available to a broader audience without prohibitive costs.
In the EV industry, the role of patent pools cannot be overstated. From battery innovation and charging infrastructure to autonomous systems and renewable energy integration, these pools enable stakeholders to overcome fragmented IP landscapes. They reduce redundancy, streamline research and development (R&D), and encourage collective progress.
Impact on the Patent Industry
Patent pools have emerged as a catalyst for reshaping the dynamics of IP in the EV sector. By offering shared access to vital technologies, these pools reduce the exclusive hold on innovations.
One of the significant benefits is the reduction of legal conflicts. In industries as competitive as EVs, patent disputes can block the progress and drain resources for various organization. Open patent pools minimize these risks by establishing clear licensing terms, fostering an environment of trust and collaboration.
Benefits of Open Patent Pools:
- Enhanced Collaboration: Patent pools allow multiple companies to share their technologies, fostering an environment of collaboration rather than competition.
- Reduced Licensing Costs: By pooling patents, companies can avoid issues like royalty stacking, making it cheaper to access necessary technologies for innovation.
- Cumulative Innovation: Open patent pools enable easier access to existing technologies, which is crucial for cumulative innovation, where new developments often rely on prior inventions.
Impact on EV Innovation:
- Stimulating Follow-on Innovation: Evidence from Tesla’s open patent strategy indicates that while initial openness may inhibit some follow-on patents, it can ultimately be good for future innovations in the EV sector.
- Strategic Focus: The optimization of patent pool strategies can enhance competitive advantages and profitability for participants, thereby promoting further innovation in EV technologies.
On the other hand, although open patent pools can foster innovation, they may also pose risks such as the possibility of collusion among participants which could restrict competition and create market inefficiencies.
In the past, high-tech enterprises primarily sought patents to safeguard their innovations and gain a competitive edge. However, with increasing innovation complexity, the Open Innovation model has gained prominence, encouraging companies to share and exchange knowledge to accelerate technological advancement. Tesla exemplifies this shift, having accumulated 3,442 patents globally, of which 2,551 are currently active.
These patents cover diverse technological areas such as battery systems, autonomous driving, and vehicle architecture. Over time, Tesla’s patenting activity has grown significantly, underlining its role as a leader in electric vehicle (EV) innovation. Importantly, Tesla’s bold move to open its patents has had a ripple effect across the EV industry, shaping the dynamics of follow-on innovations and collaborative development. Figure 1 shows this distribution and the active versus inactive status of Tesla’s patent portfolio count.
Challenges of Open Patent Pools
Despite their numerous advantages, open patent pools face challenges that must be addressed for long-term success. One significant hurdle is the valuation of contributions. Determining the worth of each patent in a pool can be disputed, requiring robust and transparent frameworks.
Governance is another critical area. Establishing equitable rules for participation, revenue sharing, and dispute resolution is essential to maintain trust among stakeholders. Moreover, ensuring that companies have sufficient incentives to share their exclusive technologies requires a balance between openness and competitive advantage.
Case Study: VIA LICENSING ALLIANCE
Via Licensing Alliance (Via LA) has established a comprehensive patent licensing framework for EV charging technologies, aiming to simplify global adoption and reduce fragmentation across standards. Their EV Charging Patent Portfolio License covers a wide range of international protocols, including CCS, CHAdeMO, GB/T, SAE J1772, IEC 62196, ISO 15118, and Tesla’s North American Charging Standard. By consolidating these technologies into a unified license, Via LA supports interoperability and offers clarity to manufacturers and infrastructure providers navigating a complex IP landscape.
To ensure transparency and ease of adoption, Via LA has introduced a structured fee model based on the type and function of EV charging equipment. As illustrated in the chart above, fees vary from $5 to $40 per unit, depending on whether the device is an AC vehicle unit, DC charger, or hybrid EVSE system. The licensing scheme applies retroactively to products implementing these standards from January 1, 2019, helping companies align their compliance retrospectively while encouraging future innovation. This initiative, including strategic partnerships with regional administrators like Japan’s ULDAGE, reflects a global push toward harmonized and accessible EV infrastructure.
This bar chart shows the license fees charged by Via LA for different types of EV charging components under their patent pool. The highest fees ($40/unit) apply to DC EVSE (DC-only, Combo) and in-vehicle DC chargers (EV-D Units), while AC EVSE without HLC incurs the lowest fee at $5/unit. Via LA’s structured fee model simplifies access to global charging standards and supports industry-wide interoperability.
How does the Role of Open Patent Pools, SEPs, and Standards in Accelerating EV & Battery Innovation?
The EV and battery industry is at the forefront of innovation, driving a sustainable transformation of transportation. However, this rapid progress also encounters a complex web of IP challenges. From battery chemistry and charging systems to software and autonomous driving, countless patents guard critical technologies. Companies must navigate these patents to bring innovations to market. In this context, open patent pools, SEPs, and technical standards have emerged as key mechanisms to streamline innovation, reduce legal friction, and ensure interoperability across the EV ecosystem. This article explores how patent pools and SEPs work, how they are licensed (bilateral vs. pooled), and how technical standards set by industry groups like SAE, ISO, IEC, IEEE, and UL accelerate innovation for both major Automobile manufacturers and startups.
Fig. 3 estimated regional distribution of EV charging standard adoption, illustrating the dominance of Combined Charging System (CCS) in Europe and rising North American Charging Standard (NACS) support in North America. This conceptual illustration shows EVs integrated into a smart, sustainable ecosystem powered by renewable energy (solar, wind) and connected by advanced charging infrastructure. Achieving this vision relies on shared innovation, open standards, and collaborative IP frameworks that allow new technologies to spread rapidly.
Today, open patent pools are helping EV innovators to build the future of transportation. These pools allow even non-contributors to access essential technologies on equal terms, lowering the barriers for startups and reducing the risk of one company holding an entire industry back. Instead of navigating the patented rights, innovators can license an entire portfolio at once and focus on building better batteries, smarter software, and faster chargers. By encouraging collaboration and reducing legal complexity, patent pools turn intellectual property into a launchpad for progress rather than a roadblock.
Understanding SEPs and FRAND
As the EV industry continues to expand globally, achieving compatibility between EVs, chargers, and networks becomes increasingly important. This level of compatibility depends heavily on something often overlooked: SEPs.
These patents cover technologies that are required to comply with established industry standards. For example, if a manufacturer wants to support a widely adopted protocol like
ISO 15118, which enables plug-and-charge communication between EVs and charging stations, it must use the patented methods embedded in that standard.
To make this work fairly across the industry, organizations such as ISO, IEC, SAE, and IEEE step in. These standard-setting bodies ensure that companies contributing patented technologies to a standard agree to license them under fair, reasonable, and non-discriminatory terms, commonly referred to as FRAND. This prevents situations where one company can charge excessively or block others from using a required technology.
The benefits of this system are significant. Because of FRAND licensing, technologies like the CCS and SAE J2954 for wireless charging are accessible to both large EV manufacturers and small startups. Everyone can implement the same core systems, which helps expand charging networks, reduce costs, and speed up development.
By encouraging openness and preventing dominant control, SEPs and FRAND policies create the foundation for the smooth adoption of shared standards. This not only supports technical innovation but also makes the EV ecosystem more efficient, accessible, and consumer-friendly.
Licensing Models: Bilateral vs. Pool-Based Licensing
When it comes to EV innovation, the way companies access patented technology can directly influence how quickly ideas turn into real-world solutions. In the traditional model of bilateral licensing, every patent must be negotiated separately. For an EV manufacturer, this often means dealing with one company for battery systems, another for charging protocols, and yet another for software. The result is a slow and costly process that can overwhelm startups and slow down even the largest EV manufacturers.
Pool-based licensing offers a smarter alternative. Instead of negotiating dozens of separate deals, patent pools allow companies to access a collection of essential patents through a single license. The terms are clear, the costs are predictable, and the process is far more efficient. In a rapidly evolving industry like EVs, where success depends on fast development and seamless integration, patent pools help innovators stay focused on creating better technology without getting lost in paperwork and legal complexity.
The Fig. 4 shows that traditional bilateral licensing requires separate agreements (arrows) on the left between an EV manufacturer and each patent holder (A, B, C). With a patent pool on the right, all patent holders contribute to a collective pool, and the EV manufacturer obtains a single license from the pool for all patents. The pooled approach greatly reduces negotiation overhead and ensures access to all essential technologies via one agreement.
How Patent Pools and SEPs Benefit OEMs and Startups?
Open patent pools help major EV manufacturers cut litigation costs, access a wide range of essential technologies, and speed up EV development. They ensure equal access to standards, boosting interoperability across the industry. By aligning with evolving regulations, pools also support sustainability goals and enhance brand credibility.
They reduce royalty stacking, making innovation more cost-effective at scale. Pools also simplify global market access by ensuring compliance with international IP and technical standards. Additionally, they foster long-term partnerships and trust among key industry players, encouraging more collaborative R&D.
Benefits for Startups and Innovators
- Lower Entry Barriers: Open patent pools give startups early access to essential technologies without complex negotiations, reducing legal risks and speeding up development.
- Transparent Licensing Costs: With fixed or published royalty rates under FRAND terms, startups can plan budgets without fearing surprise fees or lawsuits.
- More Time for Innovation: Standardized licensing lets founders focus on improving products like batteries or charging systems instead of navigating IP conflicts.
- Access to Industry Standards: Startups can confidently build to standards like CCS or ISO 15118, knowing essential patents are available on fair terms, enabling seamless market entry.
The open patent pools and fair SEP licensing create a win-win situation for the large OEMs to get a stable environment to roll out innovations globally, and startups get a fair shot at participating in the market with their innovations. The whole industry benefits from faster technological advancement and more robust competition.
Role of Standard-Setting Organizations (SSOs) in EV Innovation
Technical standards underpin the EV ecosystem, ensuring that diverse components and systems can work together seamlessly. Standard-setting organizations (SSOs) are the bodies that convene industry, academic, and government experts to develop these standards. In the EV domain, key SSOs include groups like SAE International, ISO/IEC, IEEE, and others that have defined standards for charging connectors, communication protocols, battery safety, and more. Their role is crucial: by agreeing on common specifications (for example, what shape a charging plug should have, or how a EV and charger communicate), SSOs enable interoperability across manufacturers and countries. An EV built in Asia can charge at a station in Europe, and a charger made by one company can serve vehicles from many brands.
SSOs also closely interface with the IP world. When a company’s engineers propose a technology for a standard and that technology is patented, the SSO will typically require that company to commit to FRAND licensing for that patent. This alignment ensures that standards remain open and accessible despite involving proprietary innovations. In other words, SSOs help strike a balance between innovation (allowing companies to contribute their best technologies to a standard) and accessibility (making sure those contributions don’t become choke points that others can’t implement). In the EV space, many SSOs have explicit policies that any SEP must be licensed fairly to anyone who needs it. This policy gives everyone confidence that adopting the standard won’t lead to legal trouble or ruinous fees. It also encourages companies to participate in standard development, since they know everyone will get to use the final standard, they are more willing to share their ideas upfront.
Table 3 below summarizes the key SSOs involved in the EV ecosystem, their contributions, focus areas, and their alignment with IP practices such as FRAND licensing.
The following Fig 5 compares four major EV charging standards: CCS, CHAdeMO, NACS, and ISO 15118 across three key metrics: adoption level, interoperability, and smart features . It shows that ISO 15118 excels in smart capabilities, while CCS stands out for its strong global adoption and compatibility[21-25].
Through these organizations and their standards, the EV industry has avoided a fragmented “Tower of Babel” scenario. Instead of each company pushing its own proprietary charging system or communication protocol, SSOs have helped the industry align around a small set of common standards. This common ground lowers costs (through economies of scale), promotes competition (since new entrants can adopt the same standards as incumbents), and accelerates innovation (engineers can build on top of established platforms rather than reinventing the wheel).
Crucially, the FRAND-based IP framework within SSOs means that companies can implement standards like CCS or ISO 15118 confident that they can license any embedded patents on fair terms. The collaborative work of SSOs, backed by patent pools and SEP licensing, thus sets the stage for faster and broader technological progress in EVs than any single company could achieve on its own.
EV Charging Standards Case Study: CCS, CHAdeMO, NACS, ISO 15118
One of the strongest examples of how open standards and shared IP can accelerate innovation is found in EV charging infrastructure. Over the past decade, the EV industry has aligned around a set of key charging standards, including CCS, CHAdeMO, NACS, and ISO 15118. This global convergence has allowed EVs from different manufacturers to connect to a wide range of charging networks. These standards were shaped through collaboration among EV manufacturers, technology providers, and international standard-setting organizations, often supported by patents licensed on fair and accessible terms. This collective effort has made EV charging faster to deploy, easier to scale, and more user-friendly.
The radar chart in Fig. 6 shows qualitatively illustrates how four major EV charging standards perform across three metrics: adoption level, interoperability, and smart features. We see, for example, that CCS (orange) scores highest in global adoption and compatibility (wide regional use and support by many manufacturers), while ISO 15118 (pink) leads in smart capabilities (due to its advanced Plug & Charge and V2G communication features). NACS (red) shows strong interoperability potential and growing adoption as it becomes open standard, and CHAdeMO (blue) had early strengths but is now lower in adoption. Such comparisons underscore that each standard contributed differently to the EV ecosystem’s growth, and their coexistence, managed through open standards agreements, has allowed the global EV charging network to expand rapidly without a single technology bottlenecking progress.
Each of these standards brings distinct capabilities to the ecosystem. CCS, for example, is widely adopted in North America and Europe, offering both AC and DC charging through a unified connector design. CHAdeMO, developed in Japan, was among the first to introduce fast DC charging and also laid the groundwork for early vehicle-to-grid communication. NACS, originally designed by Tesla, is now being embraced by several major EV manufacturers and is in the process of becoming a formal SAE standard. ISO 15118 adds a digital layer on top, enabling Plug and Charge functionality that allows automatic authentication and billing between the vehicle and charger. These standards are backed by patents that are typically licensed under FRAND (Fair, Reasonable, and Non-Discriminatory) terms, ensuring that no single entity can monopolize access to critical infrastructure.
This cooperative model has proven essential for scaling EV infrastructure across regions and platforms. By embracing common standards and open licensing, the industry has avoided fragmentation and made it easier for manufacturers, startups, and governments to invest in charging networks. Behind the scenes, patent pools and joint licensing agreements play a crucial role by simplifying access to complex technologies and reducing the legal and financial risks of deployment. The outcome is a global EV ecosystem that is not only technically compatible but also built on a foundation of shared innovation. This spirit of openness continues to shape the future of clean transportation.
Conclusion
The EV revolution is not only a remarkable one but also a powerful demonstration of how industries can thrive when they choose collaboration over competition. At the centre of this transformation lies a trio of interlinked strategies: open patent pools, SEPs licensed on FRAND terms, and robust technical standards developed through standard-setting SSOs. Together, these elements are reshaping the innovation landscape for EVs and creating a more inclusive and fast-moving ecosystem.
Patent pools represent a shift from isolated IP protection to shared progress. By allowing multiple patent holders to license their technologies through a unified platform, pools
simplify access, reduce legal friction, and dramatically lower barriers for participation. Whether it is a global OEM seeking efficient licensing for new EV platforms or a startup looking to enter the market without facing prohibitive legal costs, patent pools offer an efficient pathway. At the same time, SEP frameworks ensure that once a technology becomes part of a recognized industry standard, no single firm can withhold access or charge unfair royalties. These FRAND commitments allow all players to implement essential technologies, leveling the competitive field.
Technical standards shaped by organizations like SAE, ISO, IEC, IEEE, and UL ensure that EVs, batteries, and charging infrastructure work seamlessly across borders and brands. These standards define plug types, communication protocols, safety specifications, and more. Critically, they integrate patented technologies that are made broadly available under fair licensing terms. This technical cohesion accelerates infrastructure deployment and fosters consumer confidence. Moreover, by enabling small players to participate, they have broadened the base of contributors to the EV ecosystem.
Governments and regulators are increasingly stepping in to reinforce this model. Policies mandating standardization, guidelines for antitrust-safe patent pooling, and initiatives like WIPO GREEN demonstrate a growing public commitment to open innovation. These efforts align market behaviour with broader technological goals.
The future of EV innovation will be shaped not by those who hold the most patents, but by those who share them most effectively. Open patent pools, SEP frameworks, and standards are not just policy tools, they are strategic enablers for a cleaner, more connected world. By embracing these frameworks, the EV industry can accelerate progress, expand its reach, and drive meaningful impact on a global scale.
The Road Forward
When companies open, they don’t lose; they lead. By collaborating through open patent pools and standards, the EV industry is writing a new journey where innovation is abundant, access is fair, and the future is electric. Imagine a world where every company builds walls around its inventions, forcing others to negotiate access one door at a time. That’s the traditional approach to patents. Now flip the script. A patent pool is like a shared toolkit where companies place their related patents into one collective space and agree to license them together under a single, fair agreement. It’s faster, cheaper, and friendlier to innovation.
Moreover, the EV industry isn’t just changing technology, it’s changing how innovation is shared. Open patent pools turn locked-up ideas into shared tools, giving everyone a fair shot at progress. By lowering legal barriers and encouraging collaboration, they help build smarter, cleaner transportation faster. In this new journey, companies that share the technology will lead the way.
Key Takeaways:
- Open patent pools simplify access to essential technologies, enabling both established OEMs and startups to innovate without excessive licensing costs or legal hurdles.
- SEPs licensed under FRAND terms ensure that core EV standards remain universally accessible, supporting global interoperability.
- Technical standards developed by SSOs like ISO, SAE, and IEEE drive seamless integration across EVs and charging networks, building consumer trust and accelerating infrastructure deployment.
- Government-backed policies and initiatives such as WIPO GREEN reinforce collaborative innovation, helping align industry efforts with sustainability and public interest goals.
