The method of the present invention provides a labor and time saving ability to determine interrelationships within patents determined by searching, via a computer system, through patent fields to see if one or more particular pieces of alphanumeric data are common to any of the patents in the database in which the field indicia are located. Such commonality is searchable in backward or forward direction, or both, from, for example, one patent of particular interest. The method allows for presentation of families of interrelated patents within minutes rather than hours, weeks or longer by utilizing computer based technology. Further, the methodology allows for determinations of interrelationships within desired degrees of separation by manipulation of the indicative data to be searched.
