A patent agent, Daniel A. Pearson, whose main specialty is pharmaceuticals, has said:
"The patent claims in U.S. Patent No. 7,595,109 are very good claims for Eestor, especially if you believe that coating the CMBT with alumina is important for the energy storage properties they are reporting. There is nothing controversial here IP-wise.
If you want to consider a story that is not so straightforward, check out the intellectual property situation that A123 has found itself in."

Also, to place this latest patent into a context, have a look at GaryB's EEStor Spreadsheet which includes all of the related patent, trademark, FOIA, permits, info etc.
