Nokia Nokia (NYSE:NOK) is one of several high-tech companies that have made the news in recent years for filing graphene patent applications. Nokia also appears to be putting this patent knowledge into practice. In a 2015 6-K filing, Nokia reported that "Nokia Technologies developed a proof-of-concept flexible printed graphene circuit, demonstrating continued progress solving many of the technical challenges related to the practical application of the ultra-thin, transparent, flexible material." Graphene news still pops up on Nokia-related websites from time to time -- but to date, still no actual products utilizing the technology.
Aixtron Germany-based Aixtron (NASDAQ:AIXG) has even more to say about graphene. In one recent 6-K filing with the SEC, it wrote: "One focus of AIXTRON's [research] involves researching processes and systems technology for the deposition of optically active 2D semiconductor materials such as ... graphene ... AIXTRON offers a Plasma Enhanced Chemical Vapor Phase Deposition ('PECVD') technology ... employed for the deposition of complex Carbon Nanostructures (Carbon Nanotubes, Nanowires or Graphene)."
Aixtron's primary business is selling equipment that semiconductor manufacturers use to produce computer chips, LEDs, and similar high-tech stuff. As such, it behooves Aixtron to perform R&D into how to manufacture graphene products at scale. But even so, Aixtron notes that the "development of applications using Carbon Nanostructures (Carbon Nanotubes, Carbon Nanowires, Graphene) [will] possibly have a positive effect on future business," but only over the "mid- to long-term."
ASML Netherlands-based ASML (NASDAQ:ASML) is in a similar line of business to Aixtron's, but is even less enthusiastic about graphene's potential to disrupt the semiconductor industry. In a filing describing its 2014 annual general meeting of shareholders, ASML noted that: "with respect to graphene as a possible replacement for silicon ... even in the event graphene would be used as material, lithography will be required to be able to manufacture semiconductors."
