The Links Page.
I have tried to assemble here some web sites that I have found useful or that may be of use to you. Many of them are pages that have links to search engines. My first choice is normally the USPTO web site. It has a Boolean search engine that is very easy to use. It is free, but may be very slow during office hours.

EPO Searches
Searches and free PDF files
Some sites from other agents follow. Generally they have their own extensive links page so it is not worth me simply copying the links into my site. Agents tend to specialize in different areas and you can also get an idea of comparative costs for agents' services in each area of specialization.
