View patents at is a patent search engine that allows you to search for and view both U.S. and international patents; you can also perform chemical patent searches using keywords, SMILES (Simplified Molecular Input Line Entry System) strings, or by drawing the structure of a compound. Users signing up for a free account can also save searches, save documents into portfolios, set up alerts to be notified of new documents of interest, batch export data to excel and share portfolios with other users, and much more.
