Finding information on trademarks for students and entrepreneurs


As a Patent and Trademark Resource Center (PTRC), the Pennsylvania State University Libraries has a mission to support both our students and the public with finding patent and trademark information along with locating application materials.  This guide will help you get started in trademark research and find the best sources of information.  Contact the library for detailed questions or to set up an appointment for yourself or a guest speaking appearance for your class or group.
