NMC materials will dominate the global lithium-ion battery market, they should reach about 51% of the global cathode material market by 2022, driven by the increasing demand for electrical vehicle applications
For this report, we investigated the global patent landscape of NMC Lithium-ion Batteries including precursor, material, electrode and battery manufacturing issues, and all types of NMC materials, whether unmodified, modified, core-shell, or mixed with other active or inactive materials.
More than 3,300 patented inventions have been published worldwide up to March 2017 by more than 590 applicants. The first patents on NMC Li-ion batteries were filed by Japanese and Korean companies including Sony, Samsung and LG Chem in the late 1990s. The first main wave of patent publications occurred in 2000s, induced by the emergence of material manufacturers like AGC, Mitsubishi Chemical, Sumitomo Metal Mining, 3M, BASF, Umicore, Chinese battery manufacturers BAK and BYD, and universities.
Since then, patent publications have increased strongly thanks to a intense patenting activity from Japanese, Chinese and Korean battery and material manufacturers, and the emergence of electric vehicle constructors like Nissan, Toyota, BMW and Chery. The second wave of patent filings combined with an increase in patent extensions worldwide is an indication of technology maturity and market growth. Currently, more than 4,000 patents have been granted, mainly in Japan and China, and more than 3,600 patent applications are pending, mainly in the USA and China.
Know Key Players' IP Positions
More than 590 patent applicants can be found on the NMC Lithium-ion Battery patent landscape. The IP position of key players has been evaluated for precursor, material, electrode and battery manufacturing issues. For each of them, the report provides a ranking and analysis of the relative strength of the top patent holders derived from their portfolio size, patent citation network, countries of patent filings and current patent legal status. We reveal the IP strength of the key IP players involved in NMC Lithium-ion Batteries and we depict their competitive IP positions. A special focus has been placed on the main patent litigation, collaborations and license agreements related to NMC materials.
Understand Patented Technology And IP Strategy
In this report, we reveal the IP strategy and the technical choices of the main patent assignees. For each supply chain segment, including precursor, material, electrode and battery, the report includes the description of key technologies, the time evolution of patent applications, the main patent assignees and their filing countries, the key patents, the patents near expiration date and the recent patented technologies. For each supply chain segment, the >3,300 patented inventions selected for this study have been categorized by type of NMC materials, such as non-modified, modified by cation or anion substitution and mixed with other active materials.
Compare IP and Market Position
The report compares the main IP players and main market players. For each of them, it highlights the discrepancies between their market position and their IP position regarding the supply chain - whether they make precursor, material, or batteries - and the type of NMC material, such as un-modified, modified, or core-shell. The main market players are not always the main IP players.
Useful Patent Database (>8,980 Patents)
The report also includes an Excel database containing the >8,980 patents and patent applications analyzed in the study. This useful patent database allows multi-criteria searches and includes patent publication number, hyperlinks to the original documents, priority date, title, abstract, patent assignees, technological segments and legal status for each member of the patent families.
