SOPHIA ANTIPOLIS, France – October 22, 2025 │ We are thrilled to announce that the latest insights from our Q3 2025 patent monitoring service, focused on solid-state battery innovations, are now available. This release marks a significant stride in understanding the technological advancements and strategic movements within the solid-state battery sector.
Global Intellectual Property Highlights – Q3 2025
During the third quarter of 2025, the patent landscape for solid-state batteries has shown significant dynamism:
- Over 1520 new patent applications were registered, attributing much of this growth to the Chinese market. Major contributions are filed by leading companies such as LG Energy Solution, Samsung, Toyota, and Honda. It is noteworthy that Samsung and Honda have notably increased their patenting activities compared to last year
- During the quarter, over 780 patent families recorded their first granted patent, with Toyota, LG Energy Solution, Samsung, Panasonic/Sanyo, Gotion, and Yili New Energy Technology standing as the primary assignees.
- Meanwhile, over 70 granted patents were lapsed or expired, reflecting a dynamic nature in the patent lifecycle.
Our ongoing analysis indicates that the leaders in solid-state battery patent landscape, including Toyota, Samsung, LG Energy Solution, and CATL, continue to strengthen their positions, despite a downturn in Panasonic/Sanyo’s new patent outputs compared to the previous year’s averages.
