Support : Publications : Chronolog Archives : September/October 2004 Tips and Techniques for the Patent Searcher: Searching Terms of Art Occasionally, you want to search a term of art as a noun but it is found as an adjective, as in a search for a device (e.g., typewriter) but found as a modifier (e.g., typewriter keyboard). Below are some methods that may prove useful to find patents about nouns rather than adjectives. Technique 1: Use the (NOT N) operator to find only "typewriter." This is also useful in finding "England" and not "New England." For example, to retrieve the following records, use: s typewriter? (not 5n) keyboard
The (NOT N) operator can be useful, but in general, the use of NOT operators in patent work is not encouraged. Technique 2: Instead of using word order to define a word's use, use an expression that will be found in nearly every patent. The word COMPRISING means "having at least the following qualities" and is used in the preamble to a claim. So, if you're looking for something directly and you keep pulling up patents that mention the item indirectly, you can use the placement of the word "comprising" in the preamble to directly tag the item you want. To retrieve records with "typewriter" as a noun, use: s typewriter? (w) comprising/cm
