Searchable databases of some of the world's major patent and trademark offices. Tulane Libraries do not collect print copies of patents, but the full-text of many patents are freely available electronically.
EI Patents comprises millions of patents from the US Patent and Trademark Office and European Patent Office. This database can be cross-searched with other databases on Engineering Village, retrieving results both from patents and scientific literature.
Use the SciFinder Scholar search features, including the option to search by chemical structure or formula, to search for chemistry-related patents. Software provides links to full-text when available free. Web version requires registration with a tulane.edu email account.
