What is patent mapping?

Patent mapping is essentially the visualisation of the results of statistical analyses and text mining processes applied to patent documents. Patent mapping allows you to create a visual representation of information from and about patent documents in a way that is easy to understand. It is an excellent tool for assessing large sets of patent data. Using bibliographic data you can identify which technical fields particular applicants are active in, and how their filing patterns and IP portfolios change over time. It is also possible to find out which countries lead in which fields.
