A computer-implemented method and system are provided for monitoring developments in a field of prior art. The method comprises using one or more processors receive a search query including a first patent concept related to the field of prior art; search the Internet as a function of the search query; generate a first set of search results; store the first set of search results in a database; conduct a subsequent search on the Internet as a function of the search query; generate a second set of search results; compare the first and second sets of search results to identify differences in the results; and communicate the differences to a user. An ontology of patent concepts may be stored in a system database. The searches may be conducted automatically on a regular basis thereby notifying the user of any intervening changes in the field of prior art.
