  Finding the patent class and subclass using print collections

  1. Index to the U.S. Patent Classification System (Ask for at Patents Desk) This is an alphabetical subject index to the Manual of Classification. Look up your invention using common terms describing its function, effect, end-product, structure, or use. Try to avoid brand names. Write down all relevant class and subclass numbers. Especially note if a subclass number has a "+" after it.
  2. Manual of Classification (Ask for at Patents Desk) This is a large two-volume set. Look up your class/subclass numbers in these books. The subclass numbers are not necessarily listed in numerical order. Take special notice of the dot indent. Revise your search strategy as needed.
  3. Classification Definitions (Search classifications through the USPTO web site). Read these definitions to establish the scope of classes and subclasses. These often provide search notes and suggestions for further search. Design classes do not have definitions.

  Finding the patents using print collections

  • Once you have identified the relevant classes and subclasses, obtain a list of all patent numbers granted from 1790 to the present and all published applications from 2001 to the present for every class and subclass to be searched.
  • The Official Gazette (Blue volumes on tall shelves near the Patents Desk) Starting in 1872, the Patent Office has published a weekly compilation of all patents issued. Take your list of patent numbers and check them against the summaries of the patents contained in the Official Gazettes. Take special note of inventions that you may wish to see more information about. The Official Gazette contains one drawing and one claim for every patent. Most patents will have 7 digit numbers; these are utility patents. Others will be 6 digits and be proceeded by a "D". These are design patents. Go to the volume of the Official Gazette that has the corresponding number listed on the spine. The most recent volumes are paperback.
