Graham Katz: Our tool, it's designed to make the process of sort of patent landscape analysis accessible to the general public by using the AI technology. And there are two aspects of the AI technology that we've brought to bear. One facilitates the querying and document retrieval, as we call it, that uses natural language processing, to analyze the data set. So analyze the set of patents that we've loaded into the system to see what the key topics are for each patent and the key claims. And the other is what we call the natural language query system, which takes key terms in your query and finds the patents that are relevant to those.
