  1. 2022 – Ongoing innovation and customer collaboration. Many of John B. West’s innovations – creating a system to quickly get judicial decisions into the hands of legal professionals, organizing them into a living taxonomy of the law, and hiring attorneys to analyze and annotate each decision – were powerful tools to speed the important and arduous task of legal research. Now, 150 years later, they provide unique content and metadata to train and power AI and machine-learning technologies that allow legal researchers to work much faster and with more accuracy and confidence. Thomson Reuters is honored to continue building on this foundation and to carry on West’s legacy as the legal marketplace evolves.
