    By default search words are ANDed together, that is, all the words in your search must be found in order for an application to appear in your results list.

    You can search for "exact phrases" by enclosing the phrase in quotation marks. You can also separate words with the OR operator.

    AmberScope was developed to apply the principles of Network Patent Analysis (NPA) to patent searching, or what we call Network Patent Searching.

    Members of the AmberScope development team are very experienced with patent searching, recognised the limitations of current search processes, and wanted to develop a better way of searching for patents.

    AmberScope is a product of Ambercite, which was established in 2010 to commercialise NPA, and which combines the unique perspectives of a network analyst, data miners, software engineers and IP law firm Griffith Hack.

    At Ambercite, we take your legal rights seriously.
    For this reason we have developed the following policies:
