The document discusses how big data and data science techniques are bringing a "sea change" to patent analytics. These new techniques, like Hadoop and R, allow for analyzing the huge amounts of patent data in ways that were not possible before. Examples discussed include next-generation citation analysis using network diagrams, word trees to analyze patent claims, and tag clouds for discovering hedge words and synonyms. The advent of these big data analytics tools is creating new opportunities for growth in the patent analysis field.
