Our Invalidity Searches provide clients with expert analysis as to possible invalidating art that can be asserted against a current patent. Our Invalidity Searches include a Reference Comparison Chart™, which is a comparison of the claims at issue versus all of the cited references. While our competitors may offer claims charting, we go beyond simple claim comparison and analyze the entire specification as it relates to the claims at issue. Our novel approach to invalidity searching provides clients with an in-depth, yet easy to understand report to quickly determine possible invalidating art.

Search of non-patent literature, including scientific publications, trade publications, industry journals, and commercial marketing materials.
Each patent reference includes relevancy analysis, with pinpoint citations to relevant locations within the references.
