What’s likely to be the “next big thing?” What might be the most fertile areas for innovation? Where should countries and companies invest their limited research funds? What technology areas are a company’s competitors pursuing?
To help answer those questions, researchers, policy-makers and R&D directors study patent maps, which provide a visual representation of where universities, companies and other organizations are protecting intellectual property produced by their research. But finding real trends in these maps can be difficult because categories with large numbers of patents — pharmaceuticals, for instance — are usually treated the same as areas with few patents.
