Freepatentsonline (FPO) is one of the easiest online tools to use. It is comprehensive for US patents, and also includes Japanese patents and a beta test of German patents.
A chemistry research guide also includes several links to patent offices, including the US, Canada, Europe, and Japan.
For help with patent searches, contact Sally Wyman, Chemistry Subject Librarian.
