One of our readers sent me the UK Intellectual Property Office (IPO) interesting worldwide graphene patent filing analysis (from 2011), with some very nice infographics and details about graphene research. If you needed further proof about Graphene research's growing popularity, check out this graph showing yearly patent applications:

According to the IPO, the largest graphene patent applicants are Samsung, Sandisk, Harvard University, Univ Sungyunkwan and Teijin. This is rather interesting as we haven't heard any references to Sandisk's graphene research program (evidently focused on memory devices, which isn't surprising given the company's focus).

Back in January we reported about CambridgeIP (a UK-based patent consultancy) and their own graphene patent analysis. Interestingly they do not mention Harvard and Sandisk at all. In any case, the IPO Analysis is interesting and well worth a read.
