1. A method of calculating a patent claim scope rating, the method including:

  • receiving from a graphical user interface displayed on a user terminal over a network, a first input containing information about a subject patent;

    receiving from the graphical user interface over the network, a second input including disclosure selection criteria;

    formulating, using at least one processor, a search query using the first input and the second input;

    receiving a search result in response to formulating the search query, the search result including one or more reference documents;

    extracting a set of references from the one or more reference documents included in the search result, the set of references including;

    patent references cited in examination of the subject patent;

    non-patent references cited in examination of the subject patent;

    first backward references for the patent references cited in examination of the subject patent;

    second backward references for the first backward references; and

    forward references for the patent references cited in examination of the subject patent;

    calculating a first patent scope sub-rating based on a calculation using the number of references between the subject patent and a patent with the earliest priority date from a set of prior patent references, the set of prior patent references including the patent references, the first backward references, and the second backward references;

    calculating a second patent score sub-rating based on a calculation using the ratio of the patent references to the non-patent references;

    calculating a third patent scope sub-rating using a number of patent disclosures in an art context of the subject patent filed prior to the subject patent falling within a predetermined time range of the patent disclosure with the earliest priority date;

    calculating a fourth patent scope sub-rating using a content correlation between the subject patent and a set of patent disclosures in an art context of the subject patent filed prior to the subject patent, wherein the content correlation is calculated using natural language processing;

    calculating a patent claim scope rating for the subject patent based on a calculation using the first patent scope sub-rating, the second patent scope sub-rating, the third patent scope sub-rating, and the fourth patent scope sub-rating;

    generating, for output on the graphical user interface, a patent claim scope report including the patent claim scope rating; and

    transmitting, to the graphical user interface displayed on the user terminal over the network, the patent claim scope rating report.
