The patent war has already started in this sector: more than 1100 patents have been filed and a growth rate of 50 percent of new published patent in 2009! This report identifies all protected solutions and provides a comprehensive panorama of the intellectual property landscape in LiMPO4 batteries sector.
Report highlights
* Strong attractiveness of the sector - Very high research and patenting activity in the last years with a strong rise of new entrants as of 2005 (new applicants represent half the number of total applicants in 2008).
* Strategic protection of battery manufacturers but also of institutional laboratories and of end-users companies on their specific applications.
* Map of patent protection and dependency – 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.
* Segmentation by type of material – Strategic positioning of the actors on LiFePO4 cathodes (60 percent), but also other metal or combinations of metals (Mn, Co, V, Ni, etc.) (20 percent).
* Applicant’s strategy - Analysis of the patent strategy of current major players which are not necessarily the major patent holders (Sony, Toyota, A123 SYSTEMS, Valence). 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.
