--- title: Prior Art Research Services | Advanced Patent Analysis by IPVision description: Highly-effective, timely prior art research and analysis where certainty is required and the impact is high. --- [![Business Patent Perspectives | IPVision, Inc.](https://info.ipvisioninc.com/hs-fs/hubfs/Ipvisioninc/Image/logo.png?width=355&name=logo.png)](http://classic-migration-sandbox-87167.hs-sites.com/) # Prior Art Research - Patent Validity and Invalidity Analysis ## **Traditional patent keyword research is not enough!** Patent prior art research and analysis completed by IPVision includes both traditional keyword research and multiple, unique methodologies designed to overcome shifting terminology, human error and database weaknesses. A few techniques that we use to deliver timely, 'tunable' analysis include: ### **Co-Citation Patent Analysis** > Co-Citation Analysis identifies patents that cite the same prior patent art as the patent we are trying to invalidate (the "Target Patent"). ### **Same Patent Class Analysis** > We work through all patents that are in the same class pair and in the USPTO hierarchical class pairs of the Target Patent, that also meet the priority date requirements, and filter down the candidate sets by the number of keywords matched for manual review. ### **Same Patent Examiner Analysis** > We review all patents by the same examiner of the Target Patent, that also meet the priority date requirements, and filter down the candidate sets by the number of keywords matched for manual review. ### **Three Deep Patent Analysis** > When a technology landscape is developing it often takes a while for the "lexicon" to settle down to generally accepted terms. In these situations keyword searching may have significant limitations. For this and other reasons we run a "Three Deep Analysis". ### **Structured Patent Review** The narrowed set of candidate patents is then reviewed manually for relevance as prior art influencing patent validity and invalidity determination, reexamination and litigation settlement. ### Learn More ## **Prior Art Research and Analysis Supports:** - Litigation Screening - Patent Dispute Analysis - Patent Transactions - M&A Due Diligence - Patent Risk Management **IPVision [Reports, Programs](https://info.ipvisioninc.com/ipvision-reports/) and and [Project Services](https://info.ipvisioninc.com/project-services/)** [Ask for Assistance](https://info.ipvisioninc.com/contact/) ## **Patent Research Discretion and Confidence** All services are delivered by staff located in our Cambridge, Massachusetts offices or in northern California.
