CambridgeIP’s analysis of the densely populated graphene patent landscape reveals a surge in patent activity from 2007 by major corporations, leading nanotechnology research institutes and SMEs around the world. Graphene—the first 2D crystal discovered—possesses highly unusual electronic, optical and mechanical properties, and is of interest across industry fields as diverse as semiconductors and biotechnology. CambridgeIP’s IP Landscape research confirms that graphene technology systems can be complex, relying on other technologies and processes. Our work also reveals that many of the end-use sectors for graphene are relatively patent intensive.  These features of the technology space contribute to the formation of a complex and intense patent landscape.

In addition to our work assisting policy makers, major investment groups, VCs, service providers, academic research institutes & individual inventors, CambridgeIP has produced a series of IP reports inspecting Corporate and University patent activity, and exploring the ‘disruptive’ implications of graphene across a range of technology fields.

Our Graphene media coverage includes:

CambridgeIP’s graphene IP strategy, IP Landscape and IP policy work and the opinions of our experts have been covered by leading media. Our graphene patent research has been covered by Nature Materials and our Chairman, Quentin Tannock has been interviewed about the graphene IP Landscape by leading media publications including Nature News, Nature Materials and the Financial Times. Click here for more information on our graphene press and media coverage.

US20110303121 Publication Number: US20110303121 FUNCTIONALIZED GRAPHENE AND METHODS OF MANUFACTURING THE SAME Abstract The present invention relates to the novel material fluorographene (FG), methods of making fluorographene, and its applications in electronics and related fields. The fluorographene also finds use in improving the properties of composite materials by incorporating the fluorographene of the invention with one or more materials such as fluoropolymers (FP) and the like. Conventionally, FP inter-chain interactions are very weak but spread over the area of FG, FG is able to act as a very effective and compatible reinforcement.
