US and European Patents (via Engineering Village)
Engineering Village Patents give researchers the tools they need to take advantage of the scientific and technical information found within the United States and the European Union patent records. Whether preparing a patent application, tracking a technology, identifying a potential collaborator or competitor, or simply learning more about work that is being done in a particular field, patent documents are an essential source for thorough, successful research. The Engineering Village Patent databases contain 15.2 million patents filed with the United States Patent and Trademark Office (USPTO) and 5.2 million patents filed with the European Union Patent Office (EPO).
