Revving Up the Future: The Electromobility Patent Race

Written by Team PatentAssist

In the ever-evolving landscape of electromobility, innovation reigns supreme. With a growing global emphasis on sustainability and a shift towards electric vehicles (EVs), the industry is witnessing a transformational surge in technological advancements and intellectual property (IP) developments. In this blog, we'll delve into the current state of the electromobility sector, highlighting the latest patents in battery and motor technologies, instances of companies clashing in their quest for dominance, and the prevailing IP trends shaping this dynamic field.

New Patents in Battery Tech

The heart of any electric vehicle is its battery technology, and the race to create more efficient, longer-lasting, and safer batteries is relentless. Recent patent filings in this realm have introduced novel approaches and materials.

One notable development is the rise of solid-state batteries. Companies like Toyota, Samsung, and QuantumScape are competing fiercely to patent their innovations in this area. Solid-state batteries promise greater energy density, faster charging times, and enhanced safety, potentially revolutionizing the EV industry. Keeping an eye on patent filings from these industry giants provides a glimpse into the future of EV power sources.

New Patents in Motor Tech

Efficient electric motors are essential for improving EV performance and range. Innovations in motor technology are focused on reducing energy loss and increasing power output. Patents are being filed to protect advancements in magnet materials, motor control systems, and regenerative braking.

Tesla, known for its electric vehicle innovations, has been actively filing patents related to motor and powertrain technology. Their "Tabless" battery cell design patent, for example, promises to boost the range and performance of their vehicles, potentially giving them a competitive edge.

Tesla and Rivian: The Electric Vehicle Duel

Tesla and Rivian, two giants in the electric vehicle (EV) industry, find themselves entangled in a legal battle that could reshape the landscape of innovation and competition. In 2020, Tesla raised a lawsuit, accusing several of its former employees, who had joined Rivian, of breaching non-disclosure agreements. These agreements were designed to safeguard Tesla's proprietary trade secrets. The heart of the matter revolves around allegations that sensitive engineering information was surreptitiously handed over to Rivian. Recently, a California state court delivered a tentative ruling, denying the employees' requests for summary adjudication, a legal maneuver that could have resolved critical aspects of the case without a full-blown trial. As this legal drama unfolds, it underscores the high-stakes rivalry between Tesla and Rivian in the burgeoning EV market, where innovation and intellectual property protection are at the forefront of competition.

On the other hand, Rivian, a rising star in the EV industry, filed a lawsuit against Tesla, alleging that Tesla sought to poach Rivian's employees and obtain confidential information. This legal battle showcases the intense competition and the value placed on intellectual property in the electromobility sector.

Current IP Trends in Electromobility

Several notable IP trends are shaping the electromobility landscape:

1. Collaborative Patent Initiatives:

Many automakers are entering into partnerships and consortiums to collectively develop and share EV-related patents. This trend fosters innovation while addressing industry-wide challenges. One example of collaborative patent initiatives in electromobility is the "CharIN" (Charging Interface Initiative) association. CharIN is a global network of companies from the automotive and charging infrastructure industries. They work together to develop and promote the Combined Charging System (CCS) standard, which aims to establish a universal fast-charging infrastructure for electric vehicles. By collaborating on patents and sharing intellectual property, CharIN members accelerate the adoption of CCS technology, ensuring interoperability and compatibility across EVs and charging stations.

2. Licensing and Royalties:

Established players are increasingly open to licensing their patented technologies to other manufacturers. This strategy not only generates revenue but also accelerates the adoption of EVs. A notable example of licensing and royalties in the electromobility industry involves the automaker Toyota. Toyota has an extensive portfolio of hybrid and electric vehicle patents. In 2019, they announced that they would grant royalty-free licenses to their entire portfolio of vehicle electrification-related patents, including those for hybrid vehicles, electric vehicles, and fuel cell vehicles, until 2030. This move was aimed at encouraging the widespread adoption of electrified vehicles and promoting environmental sustainability by making their patented technology accessible to other manufacturers.

3. Global Patent Filing:

As the EV market expands worldwide, companies are filing patents in multiple countries to protect their innovations globally. The international patent landscape is becoming more competitive. Global patent filing is a common practice among electric vehicle manufacturers, given the international nature of the industry. Tesla, for instance, has filed patents globally to protect its innovations. Tesla's patents cover various aspects of electric vehicle technology, including battery technology, autonomous driving systems, and energy storage solutions. By filing patents internationally, Tesla can defend its intellectual property rights in multiple markets and adapt to evolving global regulations and standards.

4. Focus on Sustainability:

IP filings related to sustainable materials, recycling, and eco-friendly manufacturing processes are on the rise, reflecting the industry's commitment to reducing its environmental footprint. Volkswagen Group's "Transform 2025+" strategy is an exemplary illustration of a focus on sustainability. As part of this initiative, Volkswagen aims to become a leader in electric mobility and has committed to launching a range of electric vehicles under its various brands. They've also invested heavily in sustainable manufacturing practices and materials. For instance, they are actively researching and developing sustainable, recycled materials for use in their EVs, such as seats made from recycled plastic bottles and interior trim from renewable resources. This focus on sustainable materials aligns with the broader industry trend toward environmentally friendly practices.

5. Software and Connectivity:

With EVs becoming smarter and more connected, patents related to software, artificial intelligence, and autonomous driving systems are gaining prominence. Tesla is a prime example of the emphasis on software and connectivity in the electromobility sector. Tesla's vehicles are known for their advanced software features, over-the-air updates, and connectivity options. Tesla's Autopilot system, for instance, incorporates a suite of sensors, cameras, and sophisticated software to enable semi-autonomous driving capabilities. The company continually releases software updates to enhance vehicle performance, safety, and even entertainment options. This focus on software and connectivity not only sets Tesla apart in the EV market but also reflects the broader trend of integrating cutting-edge technology into electric vehicles to improve functionality and user experience.


In conclusion, the electromobility sector is a hotbed of innovation, where patents play a pivotal role in securing competitive advantages. From advancements in battery and motor technologies to clashes between industry giants, the industry's IP landscape is dynamic and ever-evolving. Staying updated on these developments is crucial for both industry players and enthusiasts as we witness the electrifying future of transportation unfold.
