The European Union's free patent search tool, Espacenet, offers free access to more than 80 million patent documents worldwide, containing information about inventions and technical developments from 1836 to today.
Google Scholar has a search option to include patent documents. You may also update the settings and library links to include UNLV subscriptions to scholarly articles.
Google Scholar searches for scholarly materials such as peer-reviewed papers, theses, books, preprints, abstracts and reports from many academic and technical fields. It is freely available to anyone searching the Internet; however, many of the links that lead to full text resources are not. On your first visit, go to Google Scholar Preferences and use the Library Links box to set UNLV as your source for no-fee access to many full text articles.
