Lithium Metal Phosphate Batteries Patent Landscape 2010
In the current roadmap on emerging battery technologies, LiMPO4 cathodes raises high hope concerning the possibility of efficient energy storage at high charge and discharge rate, thus raising the technical potential of hybrid and plug-in hybrid electric vehicles as well as wind and solar energy storage. Moreover, because of the safety issues raised by Li-ion batteries, LiMPO4 cathodes are of crucial interest for battery manufacturers and even end-users of batteries.
This interest results in a very high research and patenting activity in the last years. While a “patent war” has been engaged for a long time concerning the Dr. Goodenough key patent, other actors are building up their portfolio notably in China where this key patent is not extended.
The present report analyses the patent environment and notably highlights the strategy of current major players which are not necessarily the major patent holders. The question can be raised for a few of them of their possibility to evolve rapidly enough to maintain their market position towards better protected competitors.
In a sector where more than 1100 patents and patent applications have been filed, this overview of LiMPO4 cathodes provides you with a comprehensive panorama of the intellectual property landscape and helps you:
- Position your company’s R&D and IP Portfolio notably regarding to the University of Texas patent portfolio
- Identify key inventors and key players involved in specific compositions of cathode
- Understand the collaboration networks and theirs dynamics
