Abstract
Searches on patents to determine prior art violations are often cumbersome and require extensive manpower to accomplish successfully. When time is constrained, an automatically generated list of candidate patents may decrease search costs and improve search efficiency. We examine whether semantic relations inferred from the pseudo-hierarchy of patent classifications can contribute to the recognition of related patents. We examine a similarity measure for hierarchically-ordered patent classes and subclasses and return a ranked list of candidate patents, using a similarity measure that has demonstrated its effectiveness when applied to WordNet ontologies. We then demonstrate that this ranked list of candidate patents allows us to better constrain the effort needed to examine for prior art violations on a target patent.
