Systems and Methods for Using Non-Textual Information In Analyzing Patent Matters

摘要

Aspects of the present invention comprise using non-textual information in analyses of patent matters. In embodiments, patent matter similarity may comprise a combination of two or more metrics: (a) a metric that measures the textual similarity between an input patent portfolio and patent matters; (b) a metric that measures the behavior between portfolio patents and other patent matters at issue (e.g., which patents are asserted in the same proceeding with portfolio patents); (c) a metric that measures the textual similarity between the textual description and patent matters; and (d) a metric that inspects which patent matters are placed at issue by peer companies. In embodiments, patent matter similarity may be determined using textual similarity in combination with non-textual information.

主权项

1. A computer-implemented method for assessing similarity using non-textual information related to a patent matter proceeding or proceedings, the method comprising:
gathering data from one or more databases containing patent matter proceedings; for each proceeding of at least some of the patent matter proceedings, extracting one or more patent matters at issue in the proceeding and one or more entities involved in the proceeding; generating one or more nodes, each node representing a patent matter proceeding and having a set of associated attributes comprising the one or more patent matters at issue in the patent matter proceeding and the one or more entities involved in the patent matter proceeding; constructing a graph by linking nodes based upon a shared attribute from the nodes' sets of associated attributes; using the graph to calculate a distance measure between a patent matter at issue that is an associated attribute of a node in the graph and a patent matter from a patent portfolio comprising one or more patent matters that is also an associated attribute in a node in the graph; and assigning a similarity score to the patent matter at issue using the distance measure.
