Patent landscape reports describe the patent situation for a specific technology in a given country, region or on the global level. They usually start with a state-of-the-art search for the technology of interest in suitable patent databases. The results of the search are then analysed to answer specific questions, e.g. to identify certain patterns of patenting activity (Who is doing what? What is filed where?), or patterns of innovation. (Innovation trends, diversity of solutions for a technical problem, collaborations). An essential component of each patent landscape report is the visualization of these results in order to facilitate their understanding, and certain conclusions or recommendations based on the empirical evidence provided by the search and analysis.
