This guide is a collection of resources intended to help inventors navigate the research and early stage activities involved in protecting and commercializing their ideas and inventions. All of the databases at The Ohio State University Libraries are licensed for academic use only; commercial use is prohibited. If your research is primarily a learning activity, these resources may be appropriate. If your research activities are directly related to commercializing your idea or invention, please utilize open access resources (designated with *) or the materials available through the Columbus Metropolitan Public Library (CM). Any resident of the state of Ohio can register online for a Columbus Metropolitan Public library card!
