Keyword Search

Page 12 of 14

 

Keyword searching can find patents where specific words are used in the patent document. You can search in the "full text", the entire patent, or in specific "fields," or parts of the patents.

Advantages: Keyword searches are quick and don't require highly specialized search skills. Keyword searches are also most appropriate for technology that does not easily fit into one classification.

Disadvantages: Keyword searches depend solely upon the searcher's ability to anticipate and guess at how an attorney or inventor may have described an invention. Additionally, the USPTO website only allows keyword searching starting in 1976. Older patents can be searched in full text only on Google Patents.
