Network Patent Analysis (NPA™) is the process of building vast networks of patents that show the areas of technology focus within these networks. Patents are joined using citation linkages. NPA™ patent landscape maps and the resulting data in spreadsheet form can be used to:
NPA™ patent analysis is unique in its ability to both rank and group patents during patent landscaping.
Examples of commercial and marketing NPA projects are discussed here.

Ambercite and its products including Network Patent Analysis (NPA) and AmberScope analyse patent data using a statistical based approach that is based on available patent citation and ownership data. These outputs are purely mathematical in nature, and do not take into account the personal or professional opinions of any individuals or associates of Ambercite. These outputs are intended to be used as tool to help support further analysis, and should not be used by itself and without professional advice on the relevancy of this data to your unique circumstances. Data should not be relied upon to prove without any further analysis any opinion of the value, patentability, validity, freedom to operate or infringement of any patent, patents or inventions. Users should also be aware that available patent citation data is imperfect, and this will affect the results of this analysis. © Patent Analytics Holding Pty Ltd.
