3. Universities in the graphene patent landscape
• Across all years, there is a relatively high patent contribution from universities and
research institutes consistent with other relatively early-stage and research-
intensive technology spaces.

5. Example Patent 1: Andrea Ferrari
US20110269629A1
SUPERCONDUCTING MATERIALS
Assignee: ISIS INNOVATION [GB]
Inventor: GIUSTINO FELICIANO [GB]; FERRARI ANDREA C [GB]; SAVINI GIANLUCA [GB]
Publication Date: 2011-11-03
Abstract: Partially or fully saturated doped graphene materials are found to be superconducting. The saturation is with hydrogen
or halogen. Doping is performed by substitution of carbon atoms or by applying an electric field. Diamond nano-rods are also
found to be superconducting. These materials can be used in electronic devices having a gate.
6. Example Patent 2: Nokia Research Cambridge
WO2012013854A1
A GRAPHENE - TITANIUM DIOXIDE ELECTRODE
Assignee: NOKIA CORP [FI]
Inventor: WEI DI [GB]; BOWER CHRIS [GB]; RYHAENEN TEUVO TAPANI [GB]; ANDREW PIERS [GB]
Publication Date: 2012-02-02
Abstract: An electrode comprises graphene, titanium dioxide and a binder, the binder configured to facilitate the binding
together of the graphene and titanium dioxide to form the electrode.
7. Corporations in the graphene patent landscape
• The largest corporate patent portfolios in the graphene patent landscape are held
by Samsung and Sandisk, reflecting industrial interests in semiconductor and
memory-related applications.
• Key differences in corporate research and development (R&D) focus and
commercial strategies can be inferred from corporate patent filings.

12. Why graphene?
Graphene: A fast developing research-enabled
technology space, encompassing a very extensive
set of potential markets and applications.
• Graphene is the first 2D crystal discovered, with unusual electronic, optical
and mechanical properties.
• Graphene is of interest across industry fields as diverse as semiconductors
and biotechnology.
• Many graphene technology applications are in sectors which are notoriously
patent and litigation intensive
Examples of graphene applications include:
• Faster computers: More efficient transistors based on graphene could result
in thinner computer chips which use less energy and work faster.
• More sensitive and robust sensors: Biotech sensor devices, environmental
monitoring, oil & gas sensors
• Thinner and flexible displays: Flexible and transparent electronics
• Tougher and more conductive polymer composites: Much like multi-wall
nanotubes (MWNT), graphene polymer composites can make polymers and
other products, like natural rubber, stronger and electrically conductive.
13. Patenting flatland: Graphene - Overview
• Our report ‘Patenting flatland: Graphene – Exploitation
challenges’ builds on research and analysis around
university graphene patent activity, recently presented
in Nature Materials: Tannock, Q. Exploiting carbon
flatland, Nature Materials, Vol 11, 2-5, (2012)
• CambridgeIP research for Nature Materials around the graphene patent
activity and collaborations of universities has been updated and
extended to analyse the entire graphene patent landscape and focus
additionally on the activities of major corporations and leading SMEs.
In addition the report considers the impact of leaders in the publication
of non-patent literature on the patent landscape
• The report is 70 pages long and contains 45 tables and figures
Corporate/University R&D network
• Our dataset ‘Graphene patents’ is an expert verified
dataset of all graphene patents and patent applications
globally recovered in our research – more than 2,000. All
key patent information fields and all major jurisdictions are
covered.
Patent trends over time
14. Technology Profile Reports: Overview
• CambridgeIP brings its significant experience in building
patent-based technology intelligence with leading
Patent trends over time
technologists and investors to create Technology Profile
Reports.
• CambridgeIP’s patent-based approach provides a
different perspective to understanding investment in
Patents are inter-related
R&D, geographical distribution and size of markets,
market value chains, how a technology area is evolving
and what are the fundamental drivers of its long-term
performance.
• Our analysis helps readers identify and assess those
technologies where commercial value is concentrated.
Corporate/University Patents cost money and significant organisational
R&D networks
resources to secure and maintain. Patents can provide
a useful indication of those technologies that patent
holders are prepared to spend money to protect.
