UK-based legal AI company RAVN Systems has formally launched a new application to review documents for legal professional privilege (LPP) using its cognitive engine. The new service will be branded the'LPP Robot' and will be offered alongside RAVN's other AI capabilities. The system reduces the time taken in such reviews by over 80% and greatly reduces the level of manpower needed to conduct such a task. Accuracy levels are also improved. This is an important step as the ability to spot LPP documents is of critical importance to lawyers, especially where investigations of large company data sets are involved or when part of a wider discovery process due to litigation. It matters because LPP material represents communications between a lawyer and their client, which could also include privileged material between an inhouse lawyer and an executive in their company.
