How to Conduct a Preliminary U.S. Patent Search

The U.S. Government grants a patent to an inventor "to exclude others from making, using, offering for sale, or selling the invention throughout the United States or importing the invention into the United States." A trademark is a word, phrase, symbol or design, or combination of words, phrases, symbols or designs, which identifies the source of goods or services of one party from those of another. A copyright protects works of authorship, such as writings, music, and works of art that have been tangibly expressed.

WIPO Guide to Using Patent Information This Guide aims to assist users in searching for technology information using patent documents, a rich source of technical, legal and business information presented in a generally standardized format and often not reproduced anywhere else. Though the Guide focuses on patent information, many of the search techniques described here can also be applied in searching other non-patent sources of technology information.

Patent Search Aids

Cooperative Patent Classification (in Espacenet) Search by Cooperative Patent Classification codes directly; or search by "keywords" to find CPC codes most commonly given to patents that have those keywords. Esp@cenet also allows search by International Patent Classification (IPC). IPC numbers are similar to CPC but not as specific - use IPC for broader search, CPC for more precise search.
USPTO's Classification Search Page USPTO's Classification Search allows browsing and search by CPC codes only. To search by keywords or phrases in definitions of CPC classes, type "cpc scheme" plus words in the site search at upper right corner of uspto.gov; for example: cpc scheme saw blade. For more precise and detailed word search for the best CPC codes, use Cooperative Patent Classification (CPC) "keyword" search at http://worldwide.espacenet.com/classification?locale=en_EP
USPTO Patent Classification site and links Information and links to the new Cooperative Patent Classification (CPC), indexes of rough CPC equivalents to old US Patent Classification (USPC), Concordances for USPC and IPC (International Patent Classification), Indexes to the old USPC, Classification Orders (revisions in the old USPC), and more.
Index to the United States Patent Classification System USPC classification uses a very limited number of words to describe classes; sometimes you need to figure out "patentese"/"legalese"; but it can be useful as an alternate classification system, or for historical patent searches.
Publication Date: NO LONGER UPDATED as of about 2013
Cooperative Patent Classification (information and background) website by EPO - USPTO Modeled on European Patent Classification (ECLA), but has more finely divided subjects than either ECLA or US Patent Classification (USPC). Search the CPC Manual at worldwide.espacenet.com under "Classification"
Publication Date: Archive (January 2013) - present
International Patent Classification search Search and Browse IPC codes, for use in Esp@cenet, Depatisnet, Japan's IPDL, US, and other databases. IPC looks like the new CPC (Cooperative Patent Classification), but has much broader categories. Use CPC for more precise searches.

Historical, Regional, and Specialized patent lists Scroll to bottom for Utility and "X-patents". Almost 10,000 US patents were lost in the 1836 fire, and only 2622 recovered or partially recovered ones are in patft.uspto.gov. Records of titles and inventors survived, from multiple copies elsewhere
