Abstract: We present a method for partitioning article and patent literatures for the purpose of identifying sub-domains within those literatures at multiple levels. The method is based on bibliographic coupling, and is used recursively to identify fine-grained clusters of articles or patents, along with higher level aggregations of those clusters. This method is applied in an analysis of the literatures of solid-state lighting, using a comprehensive dataset of 35,851 English-language articles and 12,420 US patents published or issued during the years 1977-2004. An analysis of trends by nation and continent is reported for the entire knowledge domain as well as at the highest level of clustering. The fine-grained clusters are used to identify the hottest recent topics in both the scientific (articles) and technical (patents) literatures.
