What Ostentus is

Ostentus is a legal evidence presentation tool that works directly from RelativityOne for depositions, trials, and arbitrations. Legal teams can prepare and sequence documents, pages, paragraphs, or individual points, and can repeat items in the presentation list. During a hearing, participants can zoom, scroll, and examine presented evidence independently. RelativityOne user group permissions provide personalized evidence views, so witnesses and other participants can be restricted to permitted material while legal team members retain private analysis. The presenting party can control the display cadence or engage a hot-seat operator. Practice Mode supports simulated witness examinations and mock trials before a hearing. Ostentus automatically maintains an electronic record of evidence presented; that record can be accessed, downloaded, and distributed during or after the hearing. Delium says users and data remain within RelativityOne, avoiding evidence exports and imports for presentation, and that Ostentus data and analysis remain under RelativityOne security. It integrates with existing RelativityOne functionality and retains access to workspace evidence and analysis during presentation. Delium describes the functionality as patent-protected and lists granted patents in the United States, Australia, and Canada. The maker lists offices in Brisbane and Edinburgh.
