This paper proposes a framework for a patent threat analysis search engine. The framework employs text mining based on the patent map approach to identify which particular patent is similar to the one in dispute. The patent map is a visual representation that uses technological proximities among patents. The patent threat analysis method will analyze patent infringement issues from judgements in the USA and Europe. Having examined and compared the patent map and patent infringement analysis, we can identify what kind of product and technology are subject to the threat of patent infringement with the help of solution integration and analysis of the two different databases.
