It's not clear why carbon nanotubes are separated from fullerenes, because all carbon nanotubes are fullerenes (not all fullerenes are nanotubes, eg buckyballs.)
The press release also notes:
Carbon nanotube and quantum dot applications in electronics, where many crowded and vulnerable patents indicate a high likelihood of legal wrangling, are battles worth fighting. The large addressable markets relevant to these nanomaterials justify the cost of navigating the unfavorable patent outlook.
In healthcare/cosmetics applications nanomaterials with crowded or vulnerable patent landscapes like dendrimers, ceramic nanoparticles, and metal nanoparticles represent battles worth fighting because of the broad applicability of these materials to a number of large addressable markets.
Hidden opportunities - characterized by a favorable patent outlook and large market potential - occur in energy applications of ceramic nanoparticles like high-performance cathodes in the $48 billion battery market, and in electronics applications of nanowires which could keep Moore's Law going in the next decade.
