1. A method for identifying products potentially infringing a patent, the method comprising: determining frequencies of occurrence within the text of the patent of each word of a plurality of words in a claim of the patent to obtain a plurality of first frequencies; determining frequencies of occurrence of said each word in a neutral text unrelated to the patent and to technology of the patent to obtain a plurality of second frequencies; for said each word, calculating a ratio of the first frequency associated with said each word to the second frequency associated with said each word, thereby obtaining a plurality of ratios, a ratio of the plurality of ratios per said each word; comparing each ratio of the plurality of ratios to a first parameter to obtain a plurality of key terms, each key term of the plurality of key terms comprising a word corresponding to a ratio of the plurality of ratios that exceeds the first parameter; formulating at least one query to search for data items that include the key terms; launching the at least one query; receiving search results responsive to the at least one query; and organizing the search results according to a criterion of relevance to the patent, thereby obtaining organized search results; and outputting the organized search results.

The method of claim 1 , further comprising: determining a number of distinct search results; comparing the number of distinct search results to a limit of quantity of search results; and repeating the steps of formulating at least one query, launching the at least one query, and receiving search results before the step of organizing if the number of distinct search results exceeds the limit of quantity of search results.
