September 10, 2023 By Dinesh Parmar

Electric vehicles have started charging forward, replacing the fuel ones, one vehicle at a time, and by the speed at which they are growing, it will be no surprise when they start ruling the automobile industry in India. So, to meet the rising craze of electric vehicles, many innovations are surging up in the electric vehicles industry and so does the patent filing for them.

The Electric Revolution in India: A Path to Sustainable Mobility

With our planet choking on the smoke of petrol/diesel vehicles, the need for sustainable transportation solutions is becoming more alarming than before. Electric vehicles (EVs) are emerging globally and India is no behind. The Indian government is already charged up and is playing a pivotal role in propelling the EV revolution and positioning India as a key player in the global EV market.

Big players like Tata Motors, Mahindra & Mahindra, and Hero Electric have launched electric models to cater to the growing demand which has further influenced new entrants like Ola Electric, Ather Energy, Revolt Motors, and other start-ups to come up with their innovative EV offerings.

Since the shift to electric vehicles won’t happen overnight, the government of India is putting in all its efforts and is offering enough support to encourage people to make the switch gradually. With initiatives like (the FAME) Faster Adoption and Manufacturing of Hybrid and Electric Vehicles, aimed at incentivizing the adoption of EVs through subsidies and infrastructure development and Production Linked Incentive (PLI) schemes, offering financial incentives to EV manufacturers, the government is on a path to fulfill its ambitious plan of making India a predominantly electric vehicle market by 2030, which may happen because the change is already on the move.

People have begun to understand that our planet is suffocating due to emissions and to add more to the worry, there are rising fuel prices, depleting non-renewable resources, and the government's need to curb crude imports, all of which are pushing the production of electric vehicles in India. Thus, apart from making them attractive with advantageous features like low operating costs, noiseless, sleek design, and impressive performance, efforts like the expansion of charging infrastructure, adoption of fast-charging technology, cost reductions, convenience of charging at home, etc., are being made to make EVs more accessible to the masses.

Now, the increased adoption of EVs has also caused a sudden surge in inventions as well which is piling up patent registrations for new EV inventions, and let’s explore all about it today in this article.

Understanding Electric Vehicle Patents

Just like for any invention or creation, a patent is filed, electric vehicle innovations also fall in the category of intellectual property and hence must be protected under Indian law to prevent any chances of counterfeiting. Electric vehicle patents can be of two types which are crucial for protecting the advancements made in this field.

Utility Patent - that covers the functional aspects of an invention like battery technology, charging systems, electric motors, and energy management systems.

Design Patents - that protect the ornamental design or appearance of an invention. For EVs, design patents may apply to the vehicle's exterior and interior aesthetics.

Importance of Electric Vehicle Patents

Patent registration for EVs is vital not just for the protection of the invention but also to encourage innovation by providing inventors with exclusive rights to their inventions. It encourages businesses and individuals to invest in EV research and development to further advance the industry.

In addition to giving companies a competitive advantage, patents prevent others from using their patented technology without their permission, thus causing them to dominate the market and increase revenues. In the EV industry, some patents may become essential for industry standards. In these cases, patent holders are typically required to license their technology on fair, reasonable, and non-discriminatory (FRAND) terms to ensure widespread adoption.

Key Electric Vehicle Technologies with Patents

The automotive sector has already begun its journey toward the future of mobility, and both manufacturers and customers have embraced the idea of going electric with open arms. Thus, a lot of developments have been noted in the EV sector, and with constant innovation a lot can be seen in the future as well. Here are some EV patents granted to the manufacturers:

Battery Technology - Innovations in lithium-ion, solid-state batteries, fast-charging systems, and battery management systems are crucial for improving the range, charging speed, and lifespan of EVs.

Charging Infrastructure - Another critical aspect of EV adoption is the charging infrastructure. Patents related to fast charging stations, connectors, wireless charging technology, and smart grid integration are essential to make EVs more convenient for consumers.

Electric Motors - Advances in electric motor efficiency, power density, and control systems are essential for improving EV performance.

Energy Management - Patents related to energy management systems help optimize power usage, extend battery life, and enhance overall vehicle efficiency.

Indigenous Manufacturing - India aims to reduce its reliance on imported EV components and technologies. To achieve this, the government encourages indigenous manufacturing of EV components, which may involve licensing or acquiring patented technologies.

Licensing and Collaboration - In some cases, companies may choose to license their patented technologies to others in exchange for royalties or engage in collaborative research and development projects to accelerate innovation and reduce the overall cost of EV production.

Global Collaboration - EV innovation is not limited to India alone. Indian companies and researchers often collaborate with international partners and access global patent databases to stay updated with the latest developments in the field.

Technological Advancements - The EV industry is rapidly evolving, and patents play a crucial role in protecting innovations. Keeping an eye on the latest patents in the market helps provide insights into emerging trends and technologies in the electric vehicle sector.

Patent Challenges in the Electric Vehicle Industry

Patents drive innovations but also pose challenges that require careful attention. Some of the challenges that arise in the electric vehicle industry are:

Patent Thickets - The EV industry is highly competitive, leading to the creation of numerous patents covering similar technologies. Such an overlapping set of patent rights which is called patent thickets is making it challenging for companies to navigate intellectual property issues and for new entrants to file a patent.

Licensing and Litigation - Patent disputes are common, and companies may engage in licensing agreements or litigation to resolve conflicts over patent rights.

Access to Essential Patents - Some companies hold essential patents for key EV technologies, which can create barriers for new entrants trying to access those technologies.

Standardization - As the EV industry evolves, standardization efforts are crucial to ensure interoperability and fair competition while respecting patent holders' rights.

The Current Status and Future of Patent Filing in Electric Vehicles

Patent filing in the EV sector has seen a substantial increase in recent years. Innovations in battery chemistry, energy density, and longevity are driving the development of more efficient and affordable EV batteries. Companies are fiercely competing to secure patents in this critical area. As per the research, in 2020, more than 18,000 patents were filed with an average grant rate of 50% globally.

Since the future seems electric, we can expect continued innovation in battery technology, with a focus on improving energy density, charging speed, and overall battery life. Solid-state batteries and alternative materials may become prominent areas of patent filing. As EV adoption grows, patent filings for charging infrastructure will continue to increase. EV manufacturers will continue to explore novel materials and lightweight techniques to increase vehicle efficiency which could involve patents related to lightweight materials, aerodynamics, and advanced manufacturing processes.

Patents in autonomous driving may also evolve as vehicles become more capable of self-driving in various conditions. Companies will seek to protect their innovations in sensor technology, machine learning algorithms, and safety systems. With a growing interest in electric commercial vehicles, such as trucks and buses, patent filing in this segment is expected to rise. Innovations in electric propulsion systems and logistics solutions will play a significant role. Last but not least, as environmental concerns continue to drive the EV market, patents related to recycling and sustainable materials will become more prominent. Companies will focus on making EVs more eco-friendly throughout their lifecycle.

In a Nutshell

The race to innovate in the EV sector is going to become tougher and stronger and hence piling up of patent registrations is expected in the near future.
