Other Operators

In addition to common Boolean, proximity, and truncation operators, a number of additional operators are available in TotalPatent. These are described below.

The SINGULAR Command tells the system to only find singular versions of the word, so that it will not pick up the regular plural ending. For example, if the user wished to find the word “aid” but not records referring to the disease “AIDS,” they might use this operator.[1]

Example: SINGULAR(aid)

The PLURAL Command will ensure that the singular version of a word is not found. For example, some names may end in a regular plural ending, such as “Williams.” To ensure that “William” is not automatically picked up by the search engine, the plural command should be used.[2]

Example: PLURAL(Williams)

The ALLCAPS Command is used to find words only when they appear in all capital letters within a document. For example, a search on the initialism IT (Information Technology) would be easier if the search was limited to instances where the letters were found in all caps.[3]

Example: ALLCAPS (it)

The CAPS Command will restrict the search to instances where the word in question contains at least one capital letter, useful when searching for proper nouns that may have other common meanings.[4]

Example: "CAPS (lexisnexis)" finds LexisNexis, LEXISNEXIS, Lexisnexis, etc.

The NOCAPS Command will restrict the search to terms which contain no capital letters.[5]

Example: "NOCAPS(aid)" will locate "aid" but not "AID."

The ATLEAST Command - This command is always followed by a number, such as “ATLEAST10.” It is used when searching on a common word that can appear incidentally once or twice in many patent documents. By using this term, the user can choose to see documents where the given search term appears at least N times. N can be any integer from 1 to 255.[6]

Example: ATLEAST10(intelligence)

Although these unusual operators may not be used frequently by most patent searchers, it can be useful to be aware of the additional functionality.
