With over 150 partners from over 20 countries, the European Union’s Graphene Flagship research initiative unveils its work package devoted to biomedical technologies

An April 11, 2016 news item on Nanowerk announces the Graphene Flagship’s latest work package,

With a budget of €1 billion, the Graphene Flagship represents a new form of joint, coordinated research on an unprecedented scale, forming Europe’s biggest ever research initiative. It was launched in 2013 to bring together academic and industrial researchers to take graphene from the realm of academic laboratories into European society in the timeframe of 10 years. The initiative currently involves over 150 partners from more than 20 European countries. The Graphene Flagship, coordinated by Chalmers University of Technology (Sweden), is implemented around 15 scientific Work Packages on specific science and technology topics, such as fundamental science, materials, health and environment, energy, sensors, flexible electronics and spintronics.

Today [April 11, 2016], the Graphene Flagship announced in Barcelona the creation of a new Work Package devoted to Biomedical Technologies, one emerging application area for graphene and other 2D materials. This initiative is led by Professor Kostas Kostarelos, from the University of Manchester (United Kingdom), and ICREA Professor Jose Antonio Garrido, from the Catalan Institute of Nanoscience and Nanotechnology (ICN2, Spain). The Kick-off event, held in the Casa Convalescència of the Universitat Autònoma de Barcelona (UAB), is co-organised by ICN2 (ICREA Prof Jose Antonio Garrido), Centro Nacional de Microelectrónica (CNM-IMB-CSIC, CIBER-BBN; CSIC Tenured Scientist Dr Rosa Villa), and Institut d’Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS; ICREA Prof Mavi Sánchez-Vives).

An April 11, 2016 ICN2 press release, which originated the news item, provides more detail about the Biomedical Technologies work package and other work packages,

The new Work Package will focus on the development of implants based on graphene and 2D-materials that have therapeutic functionalities for specific clinical outcomes, in disciplines such as neurology, ophthalmology and surgery. It will include research in three main areas: Materials Engineering; Implant Technology & Engineering; and Functionality and Therapeutic Efficacy. The objective is to explore novel implants with therapeutic capacity that will be further developed in the next phases of the Graphene Flagship.

The Materials Engineering area will be devoted to the production, characterisation, chemical modification and optimisation of graphene materials that will be adopted for the design of implants and therapeutic element technologies. Its results will be applied by the Implant Technology and Engineering area on the design of implant technologies. Several teams will work in parallel on retinal, cortical, and deep brain implants, as well as devices to be applied in the periphery nerve system. Finally, The Functionality and Therapeutic Efficacy area activities will centre on development of devices that, in addition to interfacing the nerve system for recording and stimulation of electrical activity, also have therapeutic functionality.

Stimulation therapies will focus on the adoption of graphene materials in implants with stimulation capabilities in Parkinson’s, blindness and epilepsy disease models. On the other hand, biological therapies will focus on the development of graphene materials as transport devices of biological molecules (nucleic acids, protein fragments, peptides) for modulation of neurophysiological processes. Both approaches involve a transversal innovation environment that brings together the efforts of different Work Packages within the Graphene Flagship.

A leading role for Barcelona in Graphene and 2D-Materials

The kick-off meeting of the new Graphene Flagship Work Package takes place in Barcelona because of the strong involvement of local institutions and the high international profile of Catalonia in 2D-materials and biomedical research. Institutions such as the Catalan Institute of Nanoscience and Nanotechnology (ICN2) develop frontier research in a supportive environment which attracts talented researchers from abroad, such as ICREA Research Prof Jose Antonio Garrido, Group Leader of the ICN2 Advanced Electronic Materials and Devices Group and now also Deputy Leader of the Biomedical Technologies Work Package. Until summer 2015 he was leading a research group at the Technische Universität München (Germany).

Further Graphene Flagship events in Barcelona are planned; in May 2016 ICN2 will also host a meeting of the Spintronics Work Package. ICREA Prof Stephan Roche, Group Leader of the ICN2 Theoretical and Computational Nanoscience Group, is the deputy leader of this Work Package led by Prof Bart van Wees, from the University of Groningen (The Netherlands). Another Work Package, on optoelectronics, is led by Prof Frank Koppens from the Institute of Photonic Sciences (ICFO, Spain), with Prof Andrea Ferrari from the University of Cambridge (United Kingdom) as deputy. Thus a number of prominent research institutes in Barcelona are deeply involved in the coordination of this European research initiative.

Kostas Kostarelos, the leader of the Biomedical Technologies Graphene Flagship work package, has been mentioned here before in the context of his blog posts for The Guardian science blog network (see my Aug. 7, 2014 post for a link to his post on metaphors used in medicine).

A 2nd European roadmap for graphene

About 2.5 years ago there was an article titled, “A roadmap for graphene” (behind a paywall) which Nature magazine published online in Oct. 2012. I see at least two of the 2012 authors, Konstantin (Kostya) Novoselov and Vladimir Fal’ko,, are party to this second, more comprehensive roadmap featured in a Feb. 24, 2015 news item on Nanowerk,

In October 2013, academia and industry came together to form the Graphene Flagship. Now with 142 partners in 23 countries, and a growing number of associate members, the Graphene Flagship was established following a call from the European Commission to address big science and technology challenges of the day through long-term, multidisciplinary R&D efforts.

A Feb.  24, 2015 University of Cambridge news release, which originated the news item, describes the roadmap in more detail,

In an open-access paper published in the Royal Society of Chemistry journal Nanoscale, more than 60 academics and industrialists lay out a science and technology roadmap for graphene, related two-dimensional crystals, other 2D materials, and hybrid systems based on a combination of different 2D crystals and other nanomaterials. The roadmap covers the next ten years and beyond, and its objective is to guide the research community and industry toward the development of products based on graphene and related materials.

The roadmap highlights three broad areas of activity. The first task is to identify new layered materials, assess their potential, and develop reliable, reproducible and safe means of producing them on an industrial scale. Identification of new device concepts enabled by 2D materials is also called for, along with the development of component technologies. The ultimate goal is to integrate components and structures based on 2D materials into systems capable of providing new functionalities and application areas.

Eleven science and technology themes are identified in the roadmap. These are: fundamental science, health and environment, production, electronic devices, spintronics, photonics and optoelectronics, sensors, flexible electronics, energy conversion and storage, composite materials, and biomedical devices. The roadmap addresses each of these areas in turn, with timelines.

Research areas outlined in the roadmap correspond broadly with current flagship work packages, with the addition of a work package devoted to the growing area of biomedical applications, to be included in the next phase of the flagship. A recent independent assessment has confirmed that the Graphene Flagship is firmly on course, with hundreds of research papers, numerous patents and marketable products to its name.

Roadmap timelines predict that, before the end of the ten-year period of the flagship, products will be close to market in the areas of flexible electronics, composites, and energy, as well as advanced prototypes of silicon-integrated photonic devices, sensors, high-speed electronics, and biomedical devices.

“This publication concludes a four-year effort to collect and coordinate state-of-the-art science and technology of graphene and related materials,” says Andrea Ferrari, director of the Cambridge Graphene Centre, and chairman of the Executive Board of the Graphene Flagship. “We hope that this open-access roadmap will serve as the starting point for academia and industry in their efforts to take layered materials and composites from laboratory to market.” Ferrari led the roadmap effort with Italian Institute of Technology physicist Francesco Bonaccorso, who is a Royal Society Newton Fellow of the University of Cambridge, and a Fellow of Hughes Hall.

“We are very proud of the joint effort of the many authors who have produced this roadmap,” says Jari Kinaret, director of the Graphene Flagship. “The roadmap forms a solid foundation for the graphene community in Europe to plan its activities for the coming years. It is not a static document, but will evolve to reflect progress in the field, and new applications identified and pursued by industry.”

I have skimmed through the report briefly (wish I had more time) and have a couple of comments. First, there’s an excellent glossary of terms for anyone who might stumble over chemical abbreviations and/or more technical terminology. Second, they present a very interesting analysis of the intellectual property (patents) landscape (Note: Links have been removed. Incidental numbers are footnote references),

In the graphene area, there has been a particularly rapid increase in patent activity from around 2007.45 Much of this is driven by patent applications made by major corporations and universities in South Korea and USA.53 Additionally, a high level of graphene patent activity in China is also observed.54 These features have led some commentators to conclude that graphene innovations arising in Europe are being mainly exploited elsewhere.55 Nonetheless, an analysis of the Intellectual Property (IP) provides evidence that Europe already has a significant foothold in the graphene patent landscape and significant opportunities to secure future value. As the underlying graphene technology space develops, and the GRM [graphene and related materials] patent landscape matures, re-distribution of the patent landscape seems inevitable and Europe is well positioned to benefit from patent-based commercialisation of GRM research.

Overall, the graphene patent landscape is growing rapidly and already resembles that of sub-segments of the semiconductor and biotechnology industries,56 which experience high levels of patent activity. The patent strategies of the businesses active in such sub-sectors frequently include ‘portfolio maximization’56 and ‘portfolio optimization’56 strategies, and the sub-sectors experience the development of what commentators term ‘patent thickets’56, or multiple overlapping granted patent rights.56 A range of policies, regulatory and business strategies have been developed to limit such patent practices.57 In such circumstances, accurate patent landscaping may provide critical information to policy-makers, investors and individual industry participants, underpinning the development of sound policies, business strategies and research commercialisation plans.

It sounds like a patent thicket is developing (Note: Links have been removed. Incidental numbers are footnote references),,

Fig. 13 provides evidence of a relative increase in graphene patent filings in South Korea from 2007 to 2009 compared to 2004–2006. This could indicate increased commercial interest in graphene technology from around 2007. The period 2010 to 2012 shows a marked relative increase in graphene patent filings in China. It should be noted that a general increase in Chinese patent filings across many ST domains in this period is observed.76 Notwithstanding this general increase in Chinese patent activity, there does appear to be increased commercial interest in graphene in China. It is notable that the European Patent Office contribution as a percentage of all graphene patent filings globally falls from a 8% in the period 2007 to 2009 to 4% in the period 2010 to 2012.

The importance of the US, China and South Korea is emphasised by the top assignees, shown in Fig. 14. The corporation with most graphene patent applications is the Korean multinational Samsung, with over three times as many filings as its nearest rival. It has also patented an unrivalled range of graphene-technology applications, including synthesis procedures,77 transparent display devices,78 composite materials,79 transistors,80 batteries and solar cells.81 Samsung’s patent applications indicate a sustained and heavy investment in graphene R&D, as well as collaboration (co-assignment of patents) with a wide range of academic institutions.82,83

Fig. 14 Top 10 graphene patent assignees by number and cumulative over all time as of end-July 2014. Number of patents are indicated in the red histograms referred to the left Y axis, while the cumulative percentage is the blue line, referred to the right Y axis.

It is also interesting to note that patent filings by universities and research institutions make up a significant proportion ([similar]50%) of total patent filings: the other half comprises contributions from small and medium-sized enterprises (SMEs) and multinationals.

Europe’s position is shown in Fig. 10, 12 and 14. While Europe makes a good showing in the geographical distribution of publications, it lags behind in patent applications, with only 7% of patent filings as compared to 30% in the US, 25% in China, and 13% in South Korea (Fig. 13) and only 9% of filings by academic institutions assigned in Europe (Fig. 15).

While Europe is trailing other regions in terms of number of patent filings, it nevertheless has a significant foothold in the patent landscape. Currently, the top European patent holder is Finland’s Nokia, primarily around incorporation of graphene into electrical devices, including resonators and electrodes.72,84,85

This may sound like Europe is trailing behind but that’s not the case according to the roadmap (Note: Links have been removed. Incidental numbers are footnote references),

European Universities also show promise in the graphene patent landscape. We also find evidence of corporate-academic collaborations in Europe, including e.g. co-assignments filed with European research institutions and Germany’s AMO GmbH,86 and chemical giant BASF.87,88 Finally, Europe sees significant patent filings from a number of international corporate and university players including Samsung,77 Vorbeck Materials,89 Princeton University,90–92 and Rice University,93–95 perhaps reflecting the quality of the European ST base around graphene, and its importance as a market for graphene technologies.

There are a number of features in the graphene patent landscape which may lead to a risk of patent thickets96 or ‘multiple overlapping granted patents’ existing around aspects of graphene technology systems. [emphasis mine] There is a relatively high volume of patent activity around graphene, which is an early stage technology space, with applications in patent intensive industry sectors. Often patents claim carbon nano structures other than graphene in graphene patent landscapes, illustrating difficulties around defining ‘graphene’ and mapping the graphene patent landscape. Additionally, the graphene patent nomenclature is not entirely settled. Different patent examiners might grant patents over the same components which the different experts and industry players call by different names.

For anyone new to this blog, I am not a big fan of current patent regimes as they seem to be stifling rather encouraging innovation. Sadly, patents and copyright were originally developed to encourage creativity and innovation by allowing the creators to profit from their ideas. Over time a system designed to encourage innovation has devolved into one that does the opposite. (My Oct. 31, 2011 post titled Patents as weapons and obstacles, details my take on this matter.) I’m not arguing against patents and copyright but suggesting that the system be fixed or replaced with something that delivers on the original intention.

Getting back to the matter at hand, here’s a link to and a citation for the 200 pp. 2015 European Graphene roadmap,
