A Multi-patent Landscape Map (sometimes called a Full Patent Landscape Map) shows the citations to and from a "starting set" of patents (e.g. an inventor's portfolio, a company's portfolio in an area etc.).
Patent landscape maps are one element in IPVision's broader Patent Landscape Reports and technology analysis offerings.
Following is a landscape map of the 10 U.S. patents asserted by NTP against Research in Motion in “Blackberry” patent lawsuit.
