Having purchased the UK case management systems supplier Visualfiles last month, LexisNexis is continuing its spending spree with the acquisition earlier this week of not one but two US litigation support systems developers, namely Dataflight Software and CaseSoft, respectively the suppliers of the Dataflight Concordance and CaseSoft CaseMap, TextMap and TimeMap applications. The systems will be added to the LexisNexis Total Litigator portfolio of services, which already includes other litigation support products such as LexisNexis Applied Discovery and LexisNexis Court Link.
