1. Identify relevant Patent Classification and Subclassification Numbers. This can be done at the United States Patent and Trademark Office website. From this site you can do a boolean search in the Manual of Classification or browse Classification and Subclassification numbers.
2. Search the USPTO database for the particular numbers returned by the Class/Subclass search at USPTO.
