Patent research is a time consuming process. Not only do you have to research both domestic and foreign patents and applications, you must also search "non-patent literature (NPL)." NPL encompasses magazine and journal articles, newspapers, trade journals, product catalogs, the internet, tradeshows, etc. any medium or outlet that would divulge prior-art. Do not limit yourself to researching only the patent databases. The University Library subscribes to other databases that you may find useful in your non-patent literature searches.
This page provides a list of additional online patent resources beyond the official USPTO site that you may find useful in your research.
