Free Patent Cluster Searching
. . . a new online intellectual property exchange for connecting the scientific community with patent information. Described as a “visually rich, categorizing information into a fully-searchable innovation landscape of over 35,000 SparkClusters(TM), self-organizing and self-naming groups of patents and new inventions.” As new innovation is submitted, SparkIP’s arrangement of clusters [with links to landscapes] reorganizes to reflect the growing body of information.
We recommend you take some time to play around with searching to get a grasp of it’s potential.
