"A company can build a patent portfolio by doing its own R&D or buying intellectual property created by other organisations and stake a protected claim on market segments it chooses to target. The wise investor will know that just having lots of patents is not necessarily a sign of commercial success. The majority of the patents out there will never create value. To do this they need to protect applications of graphene that solve a particular customer problem better than alternative solutions so that customers will be prepared to pay a premium for the graphene product that gives them the benefit." http://investorintel.com/market-analysis-intel/identify-successful-graphene-business/ .....Peter
