Graphene: An Analysis of Worldwide Patent Filings Relating to Graphene
The patenting of graphene-related technology took off rapidly in the 2000s. The largest patent portfolio is held by Samsung, and the top two applicants have only been active in the field since 2007. Half of the applicants hold patents relating to fewer than five inventions, illustrating the youth of this emerging technology. Developments are still relatively research-based, with alarge portion of academic participation, although consumer applications such as flexible touchscreen displays are getting closer to reality. A range of different research strategies are evident from patent collaborations; Samsung exhibits a reasonable amount of collaboration whilst other top applicants show none. In contrast to the specialism evident from most applicants, Samsung is active in a very diverse range of graphene-related technology. Inventions are classified in a wide range of International Patent Classifications (IPCs), though the majority of these relate to its chemistry and processing; the others define a varying range of potential applications for graphene. Though this is a rapidly emerging technology, the trends in the current patent data indicate that it will not prove to be disruptive in itself.
Introduction
Graphene is considered a nanomaterial as it consists of sheets of carbon atoms a single layer thick in a hexagonal arrangement [1]. The number of graphene-related patent applications received at the IPO has increased over the last few years since applications in electronics, opto-electronics, and photonics devices have been discovered and are in development. The media refer to graphene as the “miracle material of the 21st Century” [2] and its public profile was recently boosted when the Nobel Prize in Physics 2010 was awarded to Andre Geim and Konstantin Novoselov of Manchester University “ for groundbreaking experiments regarding the two-dimensional material graphene.”
The media buzz around graphene is not surprising given some of its properties–it isthe thinnest known material in the universe and the strongest ever measured [4];for a crystalline structure it is elastic and can stretch up to 20% of its length;it is a very efficient electrical conductor and can sustain current densities six orders of magnitude higher than that of copper at room temperature; its charge carriers have thehighest intrinsic mobility; it has the best thermal conductivity of any material; and it is the most impermeable material ever discovered.
