Index to Manual of Classification of Patents

The Manual of Classification has over 400 classes. The Index to the Manual of Classification is where you can determine the class of your idea by searching keywords. Once you have the class or class/subclass that seems relevant, you can then switch over to the Manual of Classification to see the structure of the entire class to more accurately determine what class/subclass entry is most appropriate for you. At that point, you can then retreive all of the patent titles in that class/subclass. Provider: Internet Patent News Service.
