Introduction:
Delphion offers you several different methods for searching. The simplest search is done from the QUICK SEARCH box on the Delphion website homepage and only requires you enter a single keyword. On the Quick/Number search page, you can search by single word, simple phrase, or patent number. More complex searches allow you to specify date ranges, Boolean operators, and a host of other search criteria.
All search forms allow you to select which collections to search and, minimally, whether to search front pages or full text including claims. The more advanced search forms offer additional options.
