Today's cars are getting smarter, and the main reason behind this shift lies in patents. A new study has analyzed over 5,300 patents filed between 2005 and 2022 across five major patent offices, revealing how artificial intelligence is reshaping the automotive sector. The researchers grouped inventions into seven areas, from battery management to occupant analytics, vehicle control, and traffic infrastructure. The United States leads in total filings, while Japan excels in triadic patentsβvalid in three regionsβshowing a strong global-reach strategy. Activity is heavily focused on systems that make cars more efficient and connected, yet cybersecurity remains underβrepresented, a gap that needs addressing. Companies adopt different approaches: Toyota and Bosch protect their IP across three regions, whereas Ford and GM concentrate on the U.S. and Chinese markets. These patterns illustrate how market priorities, regulations, and tech goals drive patenting behavior, offering valuable insights for industry players optimizing IP portfolios and for policymakers aiming to fill gaps like automotive cybersecurity in future R&D agendas.
The research employs Cooperative Patent Classification (CPC) codes and keyword analysis to map ML/DL patent trends. Seven technology domains were identified: (1) vehicle control, (2) traffic infrastructure management, (3) battery management, (4) occupant analytics, (5) predictive diagnostics, (6) advanced driver assistance systems, and (7) cybersecurity. Triadic patentsβfiled simultaneously in the U.S., Europe, and Japanβaccount for about 22% of the total, with Japan holding the highest share (β35%). The U.S. leads in absolute numbers (β48% of patents), while China has rapidly risen to 18% by 2022. Geographically, regions with strong tech ecosystems (California, Shenzhen) produce highβimpact patents often linked to electric and autonomous vehicles. Corporately, Toyota and Bosch display a balanced threeβregion portfolio, reflecting a global protection strategy. In contrast, Ford and GM focus on the U.S.-China dual market, aligning with their commercial priorities. The low representation of cybersecurity patents (only 8% of the total) highlights a strategic gap, offering a clear opportunity for investors and policymakers to encourage R&D in this essential area for future road safety.
