Patent Searching: Back to the Future How to Use Patent Classification Search Tools to Create Better Searches

Abstract

The proliferation of free patent databases on the web over the last fifteen years has dramatically improved access to patent information.Ironically, as access to patent information has improved, emphasis on teaching engineering students how to search the patent literature using patent classification has waned.Recently published engineering textbooks and articles recommend that students search patent databases using keywords.However, keyword searching is unreliable and produces incomplete results.Engineering students who learn to search patent databases using keywords risk developing poor information management skills.This paper will illustrate the problems that arise in keyword searches and demonstrate strategies for teaching students how to use patent classification to improve their search results, thus encouraging the development of good information retrieval and management skills.
